摘要/Abstract

摘要： 新能源渗透率提高增加了电力系统调度运行难度，电力系统灵活性不足严重影响了新能源消纳和电网安全运行。从灵活性资源出力特性和灵活性供给能力角度入手，基于电力系统灵活性裕度指标，以最大抽蓄调峰效益、最大风电消纳电量、最小机组运行成本和最小可中断负荷调用成本为目标，计及电力系统运行约束，建立源荷储多种灵活性资源统一协调滚动调度模型。基于协调调度思想，优化日前每个调度时段各灵活性资源出力，然后利用日内超短期风电预测数据，滚动修正各灵活性资源出力状态。最后通过算例验证了模型及其调度方法的有效性和可行性。

关键词: 电力系统灵活性, 灵活性裕度, 新能源, 协调调度, 日内滚动调度

Abstract: The high penetration of new energy increases the uncertainty and fluctuation of power system, while the insufficient flexibility of power system significantly affects the accommodation of new energy and the safe operation of power grid. From the perspective of flexibility resource output characteristics and the flexibility supply capacity, a source-load-storage coordinated rolling dispatch model is established based on the power system flexibility margin index, which takes the maximum peak regulation benefit, the maximum wind power consumption, the minimum units operating cost and the minimum interruptible load cost as the objectives, and comprehensively considers the operational constraints of the power system. Based on the philosophy of coordinated dispatch, the output of each flexible resource in each period was optimized, and then the output and status of each flexible resource were revised by using the super short-term wind power forecast data. Finally, a case study is made to verify the feasibility of the proposed dispatch method.

Key words: power system flexibility, flexibility margin, new energy, coordinated dispatch, intra-day rolling dispatch
