摘要：
Microgrid integrates distributed energy resources, storage devices and controllable loads in a more effective way. Economic dispatch for microgrid is the key to economic operation of microgrid. This paper studies the problem of optimal economic dispatch for microgrid from the views of energy supply and load control. Considering shiftable load units with different load consumption characteristics, the model of shiftable load and the strategy for load shifting are proposed. The economic dispatch problem is regarded as a discrete-time optimal control problem, and the optimal economic dispatch model for microgrid based on dynamic programming is established. Then it is converted to a quadratic programming problem and the predictor-corrector interior-point algorithm is adopted to solve it. Examples analyze the influence of load shifting on the dispatch results, which prove the validity of proposed model and algorithm. © 2014 Chinese Society for Electrical Engineering.
