Sensitivity Analysis of a Local Market Model for Community Microgrids

A community microgrid is a collection of entities that can share energy among themselves. By using the community, participants can match their demand and supply through an internal local market with a significant reduction of the exchanges with the main grid. As a consequence, each participant can benefit from a reduction of its energy costs, a drop of the energy peak demanded from the main grid, and the new capability to provide energy reserve at aggregate level. In this paper, we analyze how the changes of the community market model parameters can affect both the community as a whole, and the welfare of each participants. The analysis is performed by varying the main drivers of the community market model, which are represented by community and storage tariffs, and storage capacity. The numerical results are obtained by using real data based on the MeryGrid project.
