| Abstract:Aiming at the problem of the fluctuation and randomness of photovoltaic (PV) power systems, PV device and energy storage device with the composition of PV-energy storage integrated power system and using energy management strategy for unified scheduling management is an effective solution, and it also has an important role in the economic operation of the system. According to the difference of PV output ability under different weather conditions, this paper proposes a kind of energy management strategy based on climatic conditions for PV-energy storage integrated power system. Different operation strategies are adopted according to next-day weather condition in day-ahead scheduling. Due to possible errors in the prediction of next-day weather condition, it combines with the ultra-short-term photovoltaic power forecasting technology and uses intraday rolling adjusted mechanism to make timely adjustments to the operating model. A case study verifies that the proposed strategy can optimize system operating costs and improve the economy of the system.
