Abstract: To resolve the contradiction and deviation produced by microgrids isolation decision between day-ahead market and real-time market, energy exchanges between power market and microgrid control system of two different time scales were considered. An economic dispatching model of microgrid under two-level market operating environment was proposed to make concerted decision. Simultaneously, control means of demand side response influences were introduced to decision making process to provide beneficial references for the ancillary service of microgrids coping with uncertainties. The correctness and effectiveness were verified by simulations on a typical microgrid.

Key words: decision-making, real-time market, day-ahead market, demand side response, microgrid, economic dispatch
