Abstract: In order to reduce the peak-to-valley D-value of hour-level wind power output power, and lower the negative impacts of the intermittence and fluctuation of the wind power on power grid, a wind power peak-shaving control strategy was proposed according to the hour-level wind power output instruction based on the short-term wind power forecast technology; the battery energy storage system (BESS) was used to lower the hour-level valley-to-peak difference of wind power, and the wind power fluctuation of the synthesized storage wind power output in every time scale was restricted within a certain limit of bandwidth. The paper put forward a normal distribution-based energy storage power calculation method and a BESS-based optimization control strategy, analyzed the relationship between the part peak-shaving control strategy by BESS and the energy storage capacity Simulation results proved that the energy storage capacity configuration was valid and feasible under such control strategy.
