Unite Optimal Operation Strategy of Optical Storage Microgrid Based on Improved User Side Management

Abstract

At this stage, with the continuous use of new energy sources, how to improve the utilization of new energy and the stability of micro grid has become the most important issue. In the electricity market environment, consider the effects of user side respond and energy storage systems on microgrids, a proper load transfer at the user side under the condition of a time-sharing optical storage price micro grid joint optimization operation strategy, to use for new energy sources and high stability of micro grid. Firstly, the mathematical model of the user and the energy storage system with the load response under the time-sharing electricity price is established, and an integrated system model is also established. Based on this, the optimal operation strategy of the system is proposed. The model and strategy are applied to an actual photovoltaic micro grid system in Gansu, to verify the validity of the model and strategy.
