Abstract: With the rapid development of renewable energy, pumped-storage station plays an increasingly important role in power system. In order to improve economic efficiency of both pumped-storage station and the society, it is vital to study the optimal operation strategy of pumped-storage stations.Firstly,the paper introduces current research of pumped storage participating in energy market, and then establishes a quadratic optimization model of pumped storage when participating in energy market. Besides, the model is expanded to adapt to more complex and practical occasions. Compared with the traditional mixed integer programming method, the quadratic optimization method proposed in this paper can reduce the running time and help operators to obtain more expected profits in energy market. The results of the example verify the feasibility and effectiveness of the proposed method.

Key words: pumped-storage, energy market, optimal operation, quadratic optimization model
