摘要
基于传统电站调度图,构建了系统蓄能与系统总出力的关系,以贵州电网梯级水电站群历史流量数据为例,并分别以多年平均发电量最大、系统不蓄能期望最大为优化调度方式、负荷优化分配对调度规则各变量进行整体寻优,获得了水电站群联合调度方式。检验结果表明,该运行方式可确保电网和水电系统安全高效运行,可供借鉴。
Based on traditional operation chart of power plant,the relationship between total energy storage and output in power system is set up.Taking the historical runoff data of cascaded hydroelectric stations in Guizhou Power Grid for an example,the joint dispatching operation mode of cascade hydropower stations are obtained by using the maximum annual average generating capacity and the maximum system energy storage as the optimization goals and optimizing variables for dispatching rules.The results show that t...
