Abstract
In view of the electricity demand of users and the power generation of renewable energy,an optimal scheduling model of grid-connected wind-optical-battery-waste mine pumped storage combined power generation system is established,with the optimization objective of minimizing the total operating cost of the system.Moreover,the results of the optimal scheduling are measured with the evaluation indexes of the equivalent load variance,the fluctuation rate of the contact line,and the power supply loss rate.The optimal solution is performed using CPLEX solver for the scheduling model.Through simulation on the optimal scheduling models of three different energy storage forms,it is concluded that the total cost of the hybrid energy storage in the form of storage battery and abandoned mine pumped storage reduces by 62.21%and 49.18%compared with that of the battery alone and abandoned mine pumped storage alone,respectively.The optimization results are ranked and evaluated by using the combined entropy weight rank sum ratio method,and the weighted rank-sum ratio of the wind-solar-battery-abandoned mine pumped storage combined power generation system is 0.833,with the highest score ranking.The results show that the proposed model not only improves the operation economy of the system,but also enhances the reliability of the system power supply,which verifies the rationality and effectiveness of the proposed model.关键词
