Collaborative Scheduling Optimization Method for Provincial Grid and Regional Grid Based on Grid Model Equivalence
摘要
Abstract
Some regional grids contain dispatch units.Global benefit of grid they can be realized by integrated optimization of dispatch resources in provincial grid and regional grid.The solution efficiency for integrated optimization model will be limited due to large number of units and large grid scale.The collaborative scheduling optimization method for provincial grid and regional grid based on grid model extension was proposed.First,in order to achieve a moderate and effective grid expansion model,the power transfer characteristics were clustering analyzed between regional grid's nodes and foreign grid's nodes by WARD equivalence principle,local grids composed of nodes with similar power transfer coefficient were taken as virtual nodes to compress the scale of regional grid,and whole optimization model will be formed through model combination of provincial grid and regional grid.Secondly,the dispatch resources in simplified regional grids were used as the unit to set up mathematical models which participated in the province's generation scheduling optimization with provincial dispatching units for obtaining the global optimal scheduling.Finally,the virtual node power generation scheduling was decomposed into related units in regional grid,and generation scheduling of all units in regional grid were obtained.The examples results show that the proposed method is efficient and can improve security and economic level of power grid operation.关键词
