Alternative pathways to net zero

Visualization of energy scenarios


~ PITCH ~

Final pitch slides

The problem

Currently, results from energy scenarios are presented in research papers or individual webpages. This makes it close to impossible for policy makers to get the full picture and understand the features of the net-zero Switzerland. How can policy-makers take decisions based on model-driven energy scenarios?

eco-friendliness score


~ PITCH ~

The topic of energy has arrived at the center of society, and we are beginning to understand that we can change our behavior in a positive way. Data is of value to people because it enables them to develop a better understanding of themselves and the world around them. Data from fitness trackers, for example, help to benchmark one's own body/fitness and to derive motivation for behavioral changes from it. In order to be able to act and being incentivised, one needs a benchmark (score). For future flexible tarif models, an underlying metric is needed. In a decentralized, renewable energy system the customer plays an increasingly active role For exemple by using energy when renewable energy is abundantly available and by reducing one’s consumption when there is a scarcity To show customers their potential for improvement, we would like to introduce a simple score based on individual consumption patterns. This score ensures transparency and creates the basis for effective incentive measures.

EMF Walks in Brugg

An energetic tour to rediscover the town


~ PITCH ~

We walked around the town of Brugg with a Software-Defined radio receiver and antenna, running open source software on a laptop to capture electromagnetic field emissions - observing the interplay of radio frequencies invisible to the eye or ear. We then produced a short music video with the result. Call it data art, if you like - we had fun making this together!

🎶 Credits 🎶

📡 Why? 📡

The town hosting our event has a turbulent industrial past and many energy-related infrastructure and historic sites, most of it well hidden behind the façades of residence and commerce. Noticing sensors, transformers, mobile phone antennas, and other sources of radio interference, we were also much more aware of the technology that surrounds us even within a short radius. Our aim is to passively observe the variety and mystery of the patterns that we encounter during our walk. With a bit of practice, we find interesting frequencies, and learn to localize sources of interference. We may start to "see" the city through a new lens, even though in our case it is just a 1-dimensional waterfall-like visualization called a Spectrogram.

What's next 🧑🏼‍🏫

We planned our walk using swisstopo open data shown on the GeoAdmin map shown below. Based on these locations of interesting sites, we are creating an Actionbound quest to visit the most interesting industrial sites around Brugg. We can recommend frequencies to tune into, such the ones typically emitted by public works. In the future we could offer these "high tech" tours of the smart city to school classes or tourists.

E-Mobility Analytics

As the discussion around e-mobility grows help with the transition to an all-electric mobility world is needed.


~ PITCH ~

Challenge

Nowadays there is a lot of noise around electric mobility. As car manufacturers and the world turn towards this technology with the goal of lowering greenhouse gas emissions and as this technology gains momentum, a lot of discussions arise, bringing conflicting arguments, myths, assumptions and open questions to the surface. This we have in abundance… What we lack is real data and facts based on this data to support all these theoretical discussions.

Presentation slides

This is where it becomes interesting! We have the real data and we are looking for data enthusiasts, who can crunch the data and generate some very interesting facts. How do we charge? How much energy do we actually need in order to cover our monthly mobility needs? Do people wait for low tariff or do they charge during the day? How does the typical charging profile look like? How about charging at work or at other points of interest (supermarkets etc.)? These and many more questions are waiting for your analytics skills and talent to be answered!

Data: Over two years of charging profiles (power consumption) timeseries in 15-minute resolution of more than 200 charging stations from the backend system of our e-mobility market product.

Aim: Analyze the data set in order to visualize the behavior of e-mobility drivers, bust some myths and support arguments with facts.

Idea: Here some interesting questions: How do we charge? How many people wait for low tariff? How many people charge their cars right away when returning home? How does the car’s charging logic work? How many cars are waiting for early morning to be fully charged (when drive-off time is preset by the driver)? Do people charge every day or only when the batteries are empty? Do people charge always on the same day? On which day of the week do people mostly charge? Typical charging profiles How does a typical charging profile look like? Which patterns are the most important ones? Place of charging How different is the charging behavior at work or at other places of interest? These and other questions need to be answered.

Big Picture: As the discussion around e-mobility grows, facts are needed to support assumptions, deepen our knowledge and help with the transition to an all-electric mobility world. Understanding the behavior of charging will help us not only better understand e-mobility as a whole, but could also open new horizons for products and services.

Enriching Point Clouds (LiDAR) with Meta Data

In densely populated Switzerland, high-voltage overhead lines are in many cases located in the vicinity of existing buildings.


~ PITCH ~

In densely populated Switzerland, high-voltage overhead lines are in many cases located in the vicinity of existing buildings. To protect the population from non-ionizing radiation, we want to classify all buildings near power lines using public available landscape models and register of buildings. Linking this data with LiDAR data helps us to discover any non-conforming constructions and to identify buildings which should be specially protected from non-ionizing radiation.

Graph Neural Network of a Wind Farm

Modelling Wake Interactions within a large windfarm based on a Graph Neural Network.


~ PITCH ~

The goal of this challenge is to model wake interactions within a large windfarm based on a Graph Neural Network. With the Graph Neural Network the turbines that have the largest impact on the Annual Energy Production of the whole wind farm due to wake interactions should be identified. This will allow wind farm operators to make specific changes to certain turbines in order to optimize the power production.

Mapping of Swiss PV power production in real time


~ PITCH ~

Presentation

Task:

Based on real-time data from aliunid, develop a simple algorithm/logic to estimate the current solar radiation (Wh/m2) from PV production data (kW).

Based on the obtained radiation data and the public PV data (installed power according to https://map.geo.admin.ch/ and roof area information from https://www.uvek-gis.admin.ch/BFE/sonnendach/ ) simulate the PV production in real time.

Aim

The aim is to map the total photovoltaic (PV) power produced in Switzerland in real-time without measuring each PV power plant individually. To achieve this, we want to simulate the PV power of all registered PV plants with PV plants for which aliunid has real-time data available.

Idea

It is safe to assume that two neighboring PV systems follow a very similar production curve. By measuring only one of them we could simulate the PV production of both. By extending this approach to the whole of Switzerland, the challenge is to simulate the PV output of all registered PV plants with data where aliunid already measures the real-time power output. The challenge consists of the following parts: 1. Generate location-specific irradiance data based on measured PV output all over Switzerland. 2. Apply the generated irradiance dataset to PV systems that are currently not measured based on basic information and open data (e.g., installed capacity, slope, orientation). 3. Present the results (e.g., the total amount of PV power currently produced in Switzerland) on a map, dashboard, or similar.

Big picture

Decentral Photovoltaic (PV) systems can be found all over Switzerland and their impact on the Swiss energy system is becoming increasingly relevant. Real-time information about each PV system helps to maximize its use and mitigate potential negative impacts. We will provide high-resolution data of the power output of PV systems all over Switzerland as well as historic weather data. Additionally, open data from geo.admin.ch and sonnendach.ch can be used

New interface to estimate heat demand in buildings

Development of a novel user interface/user experience for estimating the heat demand in buildings


~ PITCH ~

Imagine the next generation of building modelling tool experiences

Aim:

To develop new concept for how a user could interact with our heat demand estimation API.

Idea:

We have good models of heat demands in buildings, but there are many possible ways we can bring this to users. We want to imagine a user and use case and develop an interface that meets quickly their specific needs.

Big picture:

Heating is the biggest consumer of energy in Swiss homes and is still 60% coming from fossil fuels. This needs to change very quickly to meet climate targets and end fossil fuel dependence. Knowing the heat demand of a building is the first step towards improving efficiency and changing heating systems.

Smart-Meter CII Interoperability with Smart-Home Systems

Connect ten common smart meters to a data broker, establish a common information schema and develop apps and visualizations


~ PITCH ~

Challenge Presentation

In last year's CII -challenge, we have demonstrated how 4 Swiss DSO smart-meter (SM) deliver their energy data through their local Customer Information Interface (CII, like M-BUS oder DSMR) by using specific IoT-Adapters that will publish the data towards a common interoperability layer, the MQTT-broker.

This year, we shall extend the range of SM to include further SM like Ensor, Kamstrup, Sagemcom and explore others. We also intend to deploy some new SM-powered IoT-Adapters to allow DSO-customers easy and reasonably inexpensive local access to their energy data. And we shall report on the issues encountered with MBUS-HDLC-DLMS-COSEM, DSMR and other types of CII.

The second part of the challenge shall investigate and show how the many EMS or smart-home systems (SHS like Loxone, KNX, Homeassistant, openHAB, ioBroker, and more) may obtain the energy-data by subscribing to the MQTT-broker.

We also intend to explore how to integrate the hourly next-day price forecast from ENTSO-E over MQTT. EMS, SHS or even the IoT-Adapters may display this information or take sensible load-shifting decisions to flatten their power use.

Because of much higher energy prices, PV system operatores may lose their previous economic incentive to use as much energy as possible from their own production for their local loads. Instead, local loads may be shifted to times of relativly lower energy prices which also nicely indicate less expected load.

SolarDAO - The Digital Energy Cooperative

Accelerate the energy transition by making investment in renewables more flexible and inclusive.


~ PITCH ~

Background

e-swissolar

We exist to work at the intersection between transformative technologies and renewable energies. We are passionate to work on the creation of innovative financing instruments, decentralised energy networks or energy marketplaces. We aim to create sustainable value across the whole energy value chain for our stakeholders and for the society.

DAO

A Decentralized Autonomous Organization (DAO) is an organization whose rules are in computer code. DAOs are performed according to computer-coded rules (smart contracts), for example on a blockchain, and are subject to the joint work of their employees and members of the organization [1]. On the 27. & 28 März 2022 during the Open Legal Lab we created a legal structure for a DAO that will facilitate direct investments in PV-Systems in Switzerland that is Blockchain compatible and legally compliant.

Energy Communities

e-swissolar AG believes that energy cooperatives are highly relevant for the energy transition. An energy cooperative is a non-profit organisation whose purpose is to locally produce and deliver renewable energy to its stakeholder or members. Members jointly own and democratically control the cooperative. Cooperatives around the world share the same seven principles, which are based on values such as democracy, equality and solidarity.

Watch the video about the 7 cooperative principles:

ReFi

In 2021 in collaboration with the HSLU Institute of Innovation and Technology Management an Innocheque for e-swissolar’s innovative idea ReFi -Regenerative Finance for Smart Energy Communities (54557.1 INNO-EE) has been conducted. ReFi is an investment platform built on top of a blockchain network that has the potential to efficiently and cost-effectively mobilise and redirect funds to small-scale projects owned by private persons or energy communities not eligible for traditional funding sources. Fractional ownership-enabled tokenisation and decentalised finance has the potential to unlock investment at various levels from retail investors to institutional investors with less risk due to a liquidity lending pool. This peer-to-contract (many-to-many) borrowing/lending scheme with blockchain yields a faster financing process with no underwriting and due diligence costs. ReFi offers transparency, collaboration and fair governance for domestic energy communities, public and private investors, and DSOs as a first step; with endless possibilities that can be built on top later. In 2021 e-swissolar developed a prototype deployed on the AURORA blockchain testnet.

Distributed Autonomous Cooperative (DisCoo)

We are currently working on the development of the core architecture of the smart-contracts system and of the smart-contracts trying to build up a minimum prototype (backend) of a legally compliant decentralised autonomous cooperative.

More information will follow soon...

Pilot

More information will follow soon...

Problem

Financing

A big barrier slowing the development of both new and existing energy communities is the lack of accessible, targeted and consistent funding and financing. REScoop identified following barriers:

- Limited access to bank financing and financing tools

- Lack of financing tools for initiating energy communities

Manage Stakeholders & Resources

Energy cooperatives are relaying on the active participation of citizens and the involvement of multiple stakeholders (local authorities, local economic players, other cooperatives, etc.). Some citizens become members of the cooperatives, i.e. owners and users of the cooperative. Following challenges have been identified in this regard REScoop:

- Organisation of members

- Information and transperancy

Solution

Financing

- Create specific financing tools for energy communities

Manage Stakeholders & Resources

- Innovative Tools for Governance

Challenge

In the context of the identified problems and proposed solutions, what are the design criteria and patterns (elements) that constitute the SolarDAO. We will use the DAO Canvas developed by Felipe Duarte. The canvas is to guide groups through the process of making the most vital decisions they face in the process of imagining their DAO. We created a miro-board where we will collectively work on the DAO canvas. Further data about energy cooperatives will be provided during the event.

Gamification of building energy performance with human digital twins

Playing games where people interact and observe their impacts for data-driven modeling of occupant behavior


~ PITCH ~

Aim

This challenge uses an open-source digital twin developed at Empa (https://github.com/Khayatian/nestli) with real-life systems and data. The participants are expected to build on top of the research results, develop ways to incorporate social/occupants' behavior and build the foundation to design a game that would raise public awareness.

Idea

1) data-driven modeling of occupant behavior: In this challenge, we value the modeling of stochastic human behaviors. Given the digitalization of the energy systems, occupants' behavior is taking a more central role in designing automation and control systems. However, occupants are considered (and modeled) passive recipients of the control system to date. To obtain a more realistic assessment of occupants' interaction with building automation and control, this task shall model occupants as active agents that react and occasionally override control decisions, forcing their preferences into the building operation, which the controller has to deal with as disturbance.

2) if time permits, design a game framework based on the digital twin and the developed human twin: Energy end-users are currently taking a passive role in the energy transition. However, they have a much higher impact by changing their behaviors. For example, lowering thermal comfort voluntarily during extremely cold weather would help the energy system to avoid using fossil fuel-based energy production. This awareness may be raised by playing games where people interact and observe their impacts. Our open-source digital twin supports an open-source game for such a purpose. Code is appreciated, but conceptual level development is also sufficient.

Big picture

Building energy demand accounts for a large share of global energy consumption and carbon emission. Advanced building energy management systems can help to reduce energy consumption and carbon footprint. Although the technical design has been much investigated, the impacts of occupant behaviors are rarely considered. In addition, occupants’ behavior can be influenced by great awareness of their impacts and contribution to the energy transition.
