摘　　要：利用跨省区输电通道进行可再生能源资源广域优化配置是实现互联电网低碳化转型的重要手段,然而传统的“省调电话申请、网调手动修改”网间实时调控模式极大制约了互联电网灵活调节能力发挥。为此,提出了一种工程实用化的可再生能源跨省区消纳实时优化调度方法并完成了相应的系统开发和部署。该系统通过通道传输裕度计算、送受需求匹配、通道计划修编、潮流安全校核等手段,有效解决了可再生能源跨省区消纳在传统调控模式下面临的送受需求感知滞后、通道分配不尽优化、潮流断面校核困难等问题。试运行期间的系统运行结果表明,该系统的计算效率满足实际工程应用需求,且能够在不同的典型场景下促进可再生能源资源的广域深度利用。The use of cross-provincial transmission channels for wide-area optimal configuration of renewable energy resources is an important means to achieve the low-carbon transition of interconnected power grids.However,the traditional"provincial dispatch centre application through telephone,regional dispatch centre manual modification"inter-network real-time regulation mode greatly restricts the flexible regulation ability of interconnected power grids.To this end,an engineering practical real-time optimal dispatching method for renewable energy accommodation across provinces and regions has been proposed,and corresponding system development and deployment have been completed.This system effectively solves the problems faced by the cross-provincial accommodation of renewable energy in traditional regulation modes,such as delayed perception of supply and demand,incomplete optimization of channel allocation,and difficulty in verifying power flow sections,by calculating channel transmission margin,sending and receiving power matching revising channel plans,and verifying power flow safety.The analysis of the system operation results during the trial operation period indicates that the computational efficiency of the system meets the practical engineering application requirements and can promote the wide and deep utilization of renewable energy resources in different typical scenarios.This work is supported by China Southern Power Grid Co.,Ltd.(No.ZDKJXM20210052,No.ZDKJXM20180073).
