A Phase Generation Shifting Algorithm for Prosumer Surplus Management in Microgrids Using Inverter Automated Control

Four-wire low-voltage microgrids supply one-phase consumers with electricity, responding to a continuously changing demand. For addressing climate change concerns, national governments have implemented incentive schemes for residential consumers, encouraging the installation of home PV panels covering self-consumption needs. In absence adequate storage capacities, surplus is sold back by these entities, called prosumers, grid operator or, in local markets, other consumers. While initiatives encourage proliferation green energy resources, and ample research dedicated market designs prosumer–consumer trading, main concern distribution network operators influence power flows generated prosumers’ injection on operating states microgrids. The flow amount direction can greatly economic technical conditions radial grids. This paper proposes metaheuristic algorithm prosumer management that optimizes injections using automated control three-phase inverters, aim reducing active losses over typical day operation. A case study was performed two real networks distinct layouts load profiles, resulted efficient both scenarios. By optimally distributing generation three phases network, significant loss reductions were obtained, best results when injected an unbalanced, flow.
