发用两侧参与调峰的现货市场联合出清模式设计

针对新型电力系统下新能源装机容量大,发电侧调峰资源紧缺,弃风、弃光现象严重的问题,文中设计了一种考虑发用两侧参与调峰的现货市场联合出清模式,将发电侧深度调峰、柔性负荷调峰、新能源消纳与现货市场相结合,充分发掘发用两侧的调峰能力。首先,将独立储能和用户作为用户侧调峰资源,并根据用户是否具有实时跟踪调度指令的能力,将其分为灵活调节用户和非灵活调节用户,在此基础上设计了发用两侧参与调峰的日前市场和实时市场出清模式并建立出清模型。其次,综合考虑各市场主体的贡献和受益程度,设计了调峰辅助服务费用的结算与分摊机制。最后,通过算例验证了所提市场模式对于新能源消纳的有效性和合理性。算例分析中,文中所提市场模式相比仅发电侧参与调峰的模式可降低17.3%的弃风弃光量。

Spot market joint clearing mode with both sides of generation and customer participating in peak regulation

Due to the large installed capacity of new energy and the shortage of peak regulation resources on the generation side, there is a serious problem of abandonment of wind and light in the new power system. To solve this problem, a spot market joint clearing mode with both sides of generation and customer participating in peak regulation is proposed in this paper. Deep peak regulation on the generation side, peak regulation with flexible load, new energy consumption and the spot market are combines in this mode, which fully explores the peak regulation capabilities on both sides of generation and customer. Firstly, a model with two parts is established in this paper. The first part is for day-ahead market and real-time market, and the other one is for both sides of generation and customer participating in peak regulation. Energy storage and power customers are regarded as customer side peak regulation resources in the model. Power customers are divided into flexible adjustment customers and non-flexible adjustment customers according to the ability to track real-time scheduling instructions. Secondly, the settlement and allocation mechanism of peak regulation auxiliary service are designed, considering the contribution and benefit degree of each market subject. Finally, the effectiveness and reasonableness for new energy consumption of the proposed market mode are verified by a calculation example. The results show that the market mode proposed in this paper reduces the amount of wind and light abandonment by 17.3% compared with the mode that only the power generation side participates in peak regulation.
