Abstract: To improve the capacity of photovoltaic energy consumption, a hybrid power generation system of abandoned mine pumped storage and battery is constructed. Aiming at the hybrid power generation system, mathematical models of PV, abandoned mine pumped storage power station and battery are studied respectively. By introducing the cost of light discarding, an optimal scheduling model is proposed, which aims at the lowest total operating cost and the maximum PV energy consumption of the hybrid power generation system. Combined with power balance constraints, operation constraints of abandoned mine pumped storage power station and battery energy storage, an optimal solution of the scheduling model is obtained by means of CPLEX optimization tool. The results show that the scheduling strategy can achieve the optimal operation cost of the system and reduce the waste light effect.
