基于可靠性指标的含风电电力系统的发电和运行备用的协调调度模型
A Coordinated Dispatching Model Considering Generation and Operating Reserve for Wind Power Integrated Power System Based on ELNSR
摘要
Abstract
the probabilistic fluctuation of wind farm output and difficult to accurately predict,adjust and control bring difficult problems in both reserve capacity decision and generation dispatching of power grid integrated with large-scale wind farms.On the basis of giving a concept of expected load not supplied ratio (ELNSR),uncertain factors such as forced outage rate of units,prediction error of loads and wind farm outputs and so on are synthetically considered to derive the quantized relation between operating reserve of power grid and ELNSR,and the derived quantized relation is used as a constraint during generation dispatching to build a coordinated dispatching model considering generation and operating reserve for power grid integrated with large-scale wind farms.Simulation results of modified RTS-96 system show that the proposed model can consider both economy and reliability,coordinate the allocation of outputs from wind farms and thermal power plants,and give optimal scheme that is corresponding to the demand on reliability for the allocation of operating reserve among thermal generation units.关键词
