摘要/Abstract

摘要： 高比例风电接入加大了电力系统调峰压力。为提高系统接纳风电的灵活性和经济性，文章计及储能、需求响应等柔性资源参与建立了多资源调度模型，并针对火电机组启停阶段的运行特征，借鉴状态流分析方法，将火电机组启停阶段运行状态转移子模型嵌入多资源优化调度模型中。算例分析表明研究成果可以精细优化制定火电机组深度调峰和启停调峰调度指令，分析储能和需求响应资源的调峰效益，为多资源参与的辅助服务管理办法、补偿标准等相关研究提供决策分析工具。

Abstract: High penetration of wind power integration increases the difficult of power system peak-shaving and regulation. A multiple resource dispatch model considering storage and demand response is established in order to improve the flexibility and economy of wind power accommodation. A state transferring model to describe operation situation during start-up and shut-down processes of thermal units is established by referring to state flow analysis method, and embedded in proposed multiple resource dispatch model. Case study indicates this research work is able to be applied to precisely set up dispatch instructions for deep peak regulation and start-up & shut-down regulation, and can be used to analyze the peak regulation benefits from storage and demand response resource. The proposed method is also a decision analysis tool for research on auxiliary service of multiple resource and compensation standard.

Key words: wind power accommodation, state flow transferring model, start-up &, shut-down regulation, deep peak regulation, electric storage equipment, demand response resource
