Optimal Economic Dispatching Model of Microgrid Based on Noncooperative Game and ARMA Methods
Due to ignoring distribution network security constraints,the method of the optimal scheduling of microgrid which takes economic optimization as objective function has some shortcomings that lead to the limit of the voltage amplitude,tie line passing load etc.,and eventually affect the safe and stable operation of power system.This paper aims at the economic optimization of microgrid and the security optimization of distribution network and proposes a non-cooperative game model that considers the economy and security of the microgrid,and deals with the uncertain factors such as wind and light based on auto regressive and moving average method and scene reduction technology.The method and steps of model building are described,and the principle of model is analyzed in details.Using data for experiment,the comparison results of microgrid economic dispatching model,security dispatching model and the non-cooperative game model show that the non-cooperative game model is more in line with the actual power grid operation requirements,meeting not only the profit requirements of micro grid,but also the security constraints of distribution network,and more suitable for electricity market than the traditional methods.
