摘要/Abstract

Abstract: Given the different energy rates of multiple types of power generation units, different operation plans affect the economy of microgrids. Limited by load and power generation forecasting technologies, the economic superiority of day-ahead plans is unable to be fully utilized because of the fluctuation of loads and power sources. In this regard, a two-stage correction strategy-based real-time dispatch method for the economic operation of microgrids is proposed. Based on the optimal day-ahead economic operation plan, unbalanced power is validly allocated in two stages in terms of power increment and current power, which maintains the economy of the day-ahead plan. Further, for operating point offset during real-time correction, a rolling dispatch method is introduced to dynamically update the system operation plan. Finally, the results verify the effectiveness of the proposed method.

Key words: Real-time dispatch, day-ahead operation plan, economic operation, microgrid
