Game Analysis of Electricity Market With Considerations of Leasing-based Energy Storage Sharing for Renewable Generators
To solve the low utilization problem of energy storage in practice,a leasing-based energy storage sharing mode is proposed for renewable generators and an energy storage operator(ESO).In this mode,the ESO not only leases some energy storage to renewable generators but also independently participates in market competition with surplus capacity for arbitrage,thereby providing opportunities to improve the utilization of energy storage.To study the impacts of the leasing-based energy storage sharing mode on the competition outcomes in the market,a bi-level game model for a day-ahead electricity market is established,considering the leasing-based energy storage sharing mode.Based on bargaining theory,an optimization model is established at the upper level to determine the leasing prices of energy storage between renewable generators and the ESO.In the lower level,a multi-period non-cooperative game model for the day-ahead electricity market is developed,where renewable generators,the ESO,and conventional generators are considered to bid in the market as price-makers.Subsequently,a nonlinear complementarity approach is used to transform the bi-level game model into a single-level optimization problem for a solution.Finally,the reasonableness and effectiveness of the proposed leasing mode are verified through case studies.
