REVENUE POTENTIAL OF DIFFERENT PROSUMER TYPES AT LOCAL FLEXIBILITY MARKETS

Abstract

The actual change in the electricity system due to rising share of decentralized energy resources and new controllable loads such as heat pumps or charging stations for electrical vehicles lead to new challenges in the distribution grid. In a few hours per year, the results are high load and feed-in peaks, which can lead to local critical grid states in medium and low voltage grids. These critical grid states can be prevented with the help of local flexibility markets. Flexible grid users such as prosumers can offer their flexibility and avoid critical grid states. The price of the offered flexibility decides whether the local flexibility market is an economical solution for the congestion management of the distribution system operator. Several factors, such as grid user behaviour or existing marketing strategies, are important when preparing offers and influence the offered prices. One focus is the analysis of the different behaviour of grid users and the classification of grid user types in order to assess how minimum offers at local flexibility market could look like. Based on a developed simulation environment, the trading and pricing on the local flexibility market can be examined in different future scenarios.
