双向互动省地协调电压控制系统中的协调约束生成技术

双向互动省地协调电压控制模式符合智能电网的要求,具有广阔的应用前景.在该控制模式中,省、地两侧需要将各自的运行信息浓缩为协调约束(包括能力约束和期望约束)并提交给协调层供其决策.文中基于在线自适应分区结果,构造生成省调侧协调约束的优化模型；基于拓扑分区结果,构造生成地调侧协调约束的优化模型.省、地两侧通过实时求解上述优...

Coordinated Constraint Generating Technology for Bidirectional Interaction Based Provincial Coordinated Voltage Control System

The bidirectional interaction based coordinated voltage control mode for hierarchical electrical power control centers has broad application prospects.Provincial and prefectural control centers each provide operation information to the coordinator,in the form of coordinated constraints(including ability and expectation constraints).Methods of generating the coordinated constraints are proposed.Optimization models are created for the provincial control center and the prefectural control center respectively based on the online adaptive control zone division results and online topological partition results,respectively.By real-time online solving the above-mentioned optimization models,the coordinating constraints are obtained.The global power flow method is adopted for a transmission and distribution combined test case simulation to verify the methods proposed,which has already been put into practical application in Jiangsu power grid in early 2009.
