摘要

In order to fully excavating the active support capability of distributed photovoltaic (PV) and energy storage system (ESS), a coordinated optimal strategy for day-ahead and intra-day operation of distribution networks considering active support of PV and ESS is proposed. Day-ahead optimization model takes the operation cost as the optimization objective, and formulates day-ahead optimization scheme to provide reference for intra-day optimization. The intra-day optimization model takes the minimum weighted voltage deviation, line losses and active energy storage deviations as the optimization objective to ensure economic intra-day operation while improving the quality of power supply to the distribution network. The proposed strategy is verified using an IEEE-33 node test system. Results show that the proposed coordinated optimal strategy fully exploits the active support capability of PV and ESS, effectively reduces the operation cost of the distribution networks, and has an obvious easing effect on the voltage violation problem.
