【摘要】：经济性是电力系统运行的重要目标。电力系统是由发电厂、输电系统、配电系统及电力负荷组成的复杂系统,任一环节都可能对电力系统的经济运行产生重要影响。因此,应基于电网一体化运行的物理实际,统筹考虑发、输、配、用各环节的经济运行,以实现大电网的全局资源优化配置。文中就电厂、电网、用户3个独立主体,分别分析其经济运行模型的目标函数,并进一步构建大电网一体化经济运行的最优模型。在此基础上,结合国内电力系统"统一调度、分级管理"的管理模式,构建分电压层级的电网经济运行决策与分析架构,提出与之相适应的边界节点量价等效方法与分层电网的网络拓扑等效方法。最后,介绍了南方电网建设大电网一体化经济运行分析系统的建设思路。
[Abstract]:Economy is an important target of power system operation. Power system is a complex system composed of power plant, transmission system, distribution system and power load. Any link may have an important impact on the economic operation of power system. Therefore, based on the physical reality of the integrated operation of the power network, the overall consideration should be given to the economic operation of each link in order to realize the optimal allocation of the global resources of the large power network. In this paper, the objective functions of the economic operation model of power plant, power grid and user are analyzed respectively, and the optimal model of integrated economic operation of large power grid is further constructed. On this basis, combined with the management mode of "unified dispatching and hierarchical management" in domestic power system, the decision and analysis framework of power network economic operation at sub-voltage level is constructed. The equivalent method of boundary node quantity price and the network topology equivalent method of stratified power network are proposed. Finally, the paper introduces the construction idea of the integrated economic operation analysis system of the Southern Power Grid.
