面向需求响应市场的柔性负荷调度方法研究

Research on flexible load dispatch method for demand response market

为保障新能源的充分消纳和电力系统的安全性及可靠性,需要更多的灵活性资源参与调度,以市场化手段制定负荷聚合商等新型主体的调度运行机制,充分发挥其调节能力,对新型电力系统的建设和发展具有重要意义。从参与主体、准入条件、响应规则和补偿规则4方面分析了目前柔性负荷参与需求响应现状,根据负荷控制场景下的调频及调峰需求,构建柔性负荷优化调度模型。按照目前大部分省市所应用单边报量报价的模式,以“价格优先、容量优先”竞价原则,决定补贴价格及各负荷主体响应量。利用包括独立负荷及负荷聚合商在内的5000个柔性负荷规模系统测试调度优化速度,测试表明模型满足需求响应市场下快速高效调整负荷的需求。

In order to ensure the comprehensive integration of new energy sources and enhance the safety and reliability of the power system,it is imperative to involve more flexible resources in scheduling operations.Developing market-based mechanisms for entities such as load aggregators and fully leveraging their regulatory capabilities are crucial for advancing the construction and development of the new power system.The current situation of demand response participation in flexible loads is analyzed from the 4 aspects of participating entities,access conditions,response rules,and compensation rules.Based on the frequency and peak demand requirements in load control scenarios,an optimization dispatch model for flexible loads is constructed.The subsidy price and response quantity of each load subject are determined by the bidding principle of“price first,capacity first”,which is commonly adopted by most provinces and cities in their mode of unilateral quotation.A system test of 5000 flexible loads,including independent loads and load aggregators,is conducted to evaluate the optimization speed.The test results indicate that the model meets the requirements of rapidly and efficiently adjusting loads in the demand response market.
