Integration of a PV energy balancing and trading mechanism in a microgrid

Abstract

In this work we address the distribution of PV power generated in a microgrid connected to the main grid. Following the idea of a local energy community, the new goal instead of self-consumption maximization is to enable the local trade between PV producers and neighbored consumers in the microgrid. By using a simple ”many-to-many” lexicographic allocation and balancing algorithm between producers and consumers, we analyze the resulting price at the consumer. To control flexible loads in a high PV penetration scenario, we propose instead of price information, the use of PV energy surplus. Numerical results are given for an EV charging scenario.
