Large-scale use of prosumer flexibility in short-term electricity markets, taking into account prosumer interests
Initial Situation, Challenges and Motivation
The integration of prosumers into the energy markets is promoted both at the European level, for example in the so-called winter package, but also at the national level in order to actively involve the prosumers in the market and to integrate fluctuating renewable energies by using their flexibility. From a technical point of view, automatically-controllable prosumer components such as heat pumps, electric boilers, battery storage and e-mobility are particularly suitable for this purpose. Surveys in the MBS+ and EcoGrid EU projects have shown that there is a great interest on the prosumers side to make their flexibility available externally, in order to contribute to a rapid energy supply that is affordable for society. Unlike in Austria, there are already existing business models in the area of private flexibility marketing in Germany and Switzerland. However, due to the different legal, regulatory and economic circumstances, these can not be transferred one-by-one to Austria. Studies in the above research projects also show that the willingness of the prosumer to participate is very strongly influenced by certain factors, such as their own interests - an aspect which is not or only insufficiently taken into account in existing business models in the other countries. By comparison, financial interests play a less important role. In order to exploit the existing potential from an economic point of view, the needs of the prosumer must therefore be taken into account accordingly.
Objectives and Innovation
The project develops scalable optimization algorithms at the aggregator and prosumer level, which take into account not only the interests of the aggregator, but also the needs / interests of the prosumer. Under this premise, an optimal market-wide use and marketing of the existing flexibility in private households is to be made possible for all stakeholders. This premise is subsequently tested in large real-time operation and evaluated for selected use cases, such as the commercialization of spot and balanced energy markets as well as for the minimization of balancing energy. While existing business models are only available for a single component / technology, the planned project is designed to increase the flexibility of several different components in a household, such as heat pumps, electric boilers, battery storage and e-mobility, and to make use of these markets across a range of selected (system) services.
As an interface to the market, a platform (Flex+ platform) is being developed which is used for the coordination of prosumers and suppliers and is responsible for marketing, planning and forecasting, aggregation as well as the demand for the prosumer flexibility. Prosumers have the possibility to specify their individual interests by means of a user interface developed in the project together with the future users, and thereby influence the marketing potential of flexibility. Since there are no existing solutions for such a platform as well as for the dynamic interaction between the Flex+ platform and prosumers, which take into account the interests of prosumers, corresponding concepts are developed, implemented and tested in this project. Further objectives in the project are the development of appropriate procedures for forecasting the usable flexibility of private households as well as consideration of possible effects on the electricity grid (in close coordination with the ongoing lead project LEAFS). In order to ensure a high acceptance of the developed solutions, users are integrated into the project by means of co-creation over the entire
Expected Results and Findings
Based on the results of the real-time operation, remuneration models and tariffs for prosumers are developed and necessary processes for prosumers and companies are implemented along the entire value chain.
