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。

Economy is an important target for power system operation.The power system is composed of four sections, generation,transmission,distribution and consumption,each with significant impact on the economical operation of the system.Therefore,the integration of generation,transmission,distribution and consumption should be carried out based on the physical actualities towards the target of economy.First,specific obj ectives for power plants,power grids and the demand-side are separately set.Then,the integrated economical operation model is formulated.On this basis,the actual managing mode of“unified control,hierarchical management"in China”s power system is considered.And a hierarchical economical operation model is further proposed along with techniques for equivalence of boundary node,network topology and price signal. Finally,the corresponding idea in China Southern Power Grid”s on economical operation analysis of integrated power systems is treated.
