大容量储能参与受阻新能源消纳的集中竞价方法研究
Study on Centralized Bidding Method for Large-Capacity Energy Storage with Blocked New Energy Consumption

现阶段大容量储能电站逐步并网，对其采用削峰填谷的调控方式可有效促进受阻新能源消纳，但大容量储能会产生充放成本，亟需研究电价激励方法来提升其参与消纳的积极性。首先分析大容量储能参与受阻新能源消纳的技术经济可行性。其次基于电力辅助服务市场，构建大容量储能电站与新能源发电企业之间的直接交易模式。再次考虑新能源发电企业的追加报价行为，建立日前集中竞价日内调用的市场机制，并提出大容量储能参与受阻新能源消纳的集中竞价方法。最后通过算例分析验证所提方法的可行性。
At the present stage, large-capacity energy storage power stations are gradually connected to the grid. The use of peak-shaving and valley-filling regulation can effectively promote the absorption of blocked new energy sources, but large-capacity energy storage will result in charging and discharging costs, it is urgent to study the incentive method of electricity price in order to enhance the enthusiasm of its participation. Firstly, it analyzes the technical and economic feasibility of large-capacity energy storage participating in the absorption of blocked new energy. Secondly, it constructs a direct transaction model between large-capacity energy storage power station and new energy power generation enterprise based on the electricity ancillary service market. Thirdly, considering the additional bidding behavior of the new energy generation enterprises, the market mechanism of day-ahead centralized bidding is established, and the centralized bidding method of large-capacity energy storage is proposed. Finally, an example is given to verify the feasibility of the proposed method.
