The research on an optimal dispatch model of micro-grid

With the gradual development of the micro-grid construction, the problem of micro-grid optimal dispatch has become the key of depth application. Based on the operating characteristics of Distributed generation (DG) and load changes, the paper establishes an optimal dispatch model of Micro-grid. The model is solved by particle swarms optimization. At last the control strategy of micro-grid island operation and network operation is developed. The simulations of examples prove the effectiveness of the model.
