含备用储能的 5G 基站虚拟电厂参与电力市场的交易策略研究

With the sharp increase in fifth generation mobile communication base station construction, the backup battery of the base station will be a huge potential energy storage resource. The market-oriented reform of electricity in China is constantly advancing, and studying the backup energy storage of 5G base stations to participate in electricity market transactions is an effective way to achieve mutual benefits and win-win situation for power grids and communication operators. Considering the particularity of 5G base station reserve energy storage participating in the power market, this paper establishes a base station energy storage battery model considering the degradation cost and the schedulable capacity and aggregates the scattered base stations into 5G base station Virtual power plant. Then, taking the 5G base station VPP as an independent bidding entity, a bi-layer Decision model for the transaction of the electric energy FM ancillary service market is constructed, and the bi-layer model is transformed into a solvable mixed integer programming problem using KKT conditions and duality theory. Finally, an example is given to evaluate the schedulable capacity of 5G base station reserve energy storage and the effectiveness of the proposed transaction Decision model.
