需求响应参与系统调峰研究综述

由于我国电力供需矛盾和系统负荷峰谷差逐渐加大,需求响应措施在需求侧管理中得到广泛地应用。通过采用价格和激励措施,电力部门引导用户改善用电负荷,达到调峰的效果。以需求响应调峰可行性、优化模型以及评估方法为立足点,对需求响应参与系统调峰研究进行综述。首先,分析了用户的调峰特性。接着讨论了电价制定方法以及电价参与调峰的优化模型建立。然后概述了激励和电价联合参与调峰及需求侧资源参与系统长期调峰,并介绍了需求响应调峰效果的评估方法。最后,结合需求侧管理和智能电网的发展要求,对需求响应参与系统调峰的研究方向进行展望。

Review of demand response participating in power system peak shifting

Due to the remarkable increase of unbalance between power supply and demand as well as load variation, demand response has been widely applied in electricity management in China.Through the use of price and incentive measures, power utilities can guide users to improve their electricity consumption behavior, resulting in effective load management.This paper is intended to make a survey on demand response applications in power system peak shaving, including the feasibility of peak shaving, optimization model and evaluation method.The characteristics of power user''s peak shaving are analyzed first.Second, formulation method and the optimization model of peak load management based on electricity price are discussed.Then the paper summarizes the peak shaving researches based on the combination of incentive and price, and the long?term peak shaving considering the participation of demand side resources.The evaluation methods of peak shaving effect by demand response are also introduced.Finally, vistas of this research topic are projected into the future.
