摘要
作为参与电力市场或电网调度的先决条件,确定虚拟电厂整体的运行特性在最近几年得到广泛研究。以算法的原理与优缺点为立足点,对虚拟电厂中分布式能源的运行特性聚合方法进行综述。从经济性和技术性两个角度出发,分析虚拟电厂中分布式能源的运行特性聚合难点;详述技术型虚拟电厂的可调节功率域和调节功率成本等两种运行特性的聚合算法;归纳商业型虚拟电厂作为价格接受者和价格制定者的竞标电价和竞标电量确定方法;最后,结合未来高比例新能源系统的发展要求,展望虚拟电厂运行特性聚合算法的研究方向。
As the prerequisite for participating in the power market or grid scheduling, determining the overall operation characteristic of virtual power plant has been widely studied in recent years. Based on the principle and advantages and disadvantages of the algorithm, the operation characteristic aggregation method of distributed energy resource in virtual power plant is summarized in this paper. First, the difficulties of operation characteristic aggregation of distributed energy resource in virtual power plants are analyzed from the perspectives of economy and technology. Then, as technical virtual plants, the aggregation algorithms of adjustable power domain and adjustable power cost are introduced. Determination methods of bidding electricity price or bidding electricity quantity of commercial virtual power plants as price receiver and price maker are described in detail. Finally, combined with the development requirements of high proportion new energy system in the future, the research direction of operating characteristic aggregation algorithm of virtual power plant is prospected.
