Abstract

In order to improve the output stability of photovoltaic power plants and ensure power quality, it is necessary to optimise the allocation of energy storage capacity in photovoltaic power plants. This paper proposes an optimal allocation method of energy storage capacity based on Teaching-Learning-Based Optimization （TLBO） algorithm. Considering the impact of multiple factors on PV output, a two-layer energy storage capacity optimisation model is constructed. The upper layer is solved by the TLBO algorithm with the objective function of minimising the whole life cycle cost of energy storage; the lower layer is solved by the Gurobi solver with the objective function of maximising the operating revenue, and the optimal daily operation strategy is solved by the Gurobi solver. Finally, a real PV power plant in Daqing is taken as an example for simulation, and the simulation results show the effectiveness of the method.
