Comparison of Modeling Methods of Dynamic Economic Dispatch With Stochastic Wind Power Integration

Main challenges brought by large scale wind power integration to economic dispatch model is how to deal with randomness of wind power, how to decline its influence to optimal dispatch of power system. Modeling is the core step to optimal dispatch of power system with large-scale wind integration. Therefore, we review several typical modeling methods in economic dispatch with wind power integration. Furthermore, dispatch simulation on IEEE 39-bus system and a real provincial power system is performed. Comparison study on six modeling methods of stochastic dynamic economic dispatch with wind power integration, and 3 evaluation indices are used to analysis these models. The simulation results show that a fast solution to small-sized model is enough when the accuracy requirement of dispatching not high; An accurate solution with high-performance computing clusters can be performed when the dispatch center has brilliant compiling environments.
