    Abstract:

    The development of green and clean energy represented by wind and photovoltaic energy has become the trend of the times. At the same time, as the country deepens the process of coal de-capacity, a large number of coal mines have been abandoned, and research on waste mine management has received much attention. To this end, this paper firstly design the basic structure of the abandoned mine pumped storage station, and mathematically model the operating power and different operating conditions of the abandoned mine pumped storage station. On this basis, aiming at reducing the investment cost of abandoned mine pumped storage station, the operation and maintenance cost of mine distribution network system, and the penalty cost of abandoned wind and photovoltaic shortage and load shortage, the optimal configuration model of abandoned mine pumped storage station is constructed.The optimized configuration model is solved by a hybrid particle swarm and a simulated annealing algorithm.Based on the improved IEEE 14-node distribution network system, the test cases are established.The effects of the installed capacity of the waste mine and the access node on the objective function in different scenarios are compared.The effectiveness of the optimized configuration model and algorithm is analyzed and verified. Relevant parameters such as installed capacity and site selection of abandoned mine pumped storage station is determined.
