Research on configuration planning of energy storage system for new energy photovoltaic stations

Based on the energy storage configuration planning of photovoltaic power stations, this paper first establishes the energy storage charging and discharging life and new energy operating cost models, then proposes to consider the life cycle constraints of the energy storage system and the constraints of actual operating conditions,and adopts particle swarm optimization algorithm to achieve multi-objective optimization calculation based on economic objectives. Finally, simulation calculation and analysis are carried out with practical examples. It is verified that the proposed method can realize the economical operation of photovoltaic + energy storage power station and improve the utilization rate of photovoltaic resources.
