[Abstract]:Microgrid contains uncertain power supply and load, such as renewable energy and electric vehicle, which is not conducive to the stable operation of microgrid. Based on the microgrid system of scenery storage and considering the temporal and spatial distribution characteristics of electric vehicles, a dynamic electricity price adjustment strategy is proposed. According to the real-time data of renewable energy output and load, the unbalanced power in the current micro-grid is obtained, and the corresponding electricity price information is released according to the current imbalance rate (UR),. The electric vehicle is fully mobilized to participate in the dispatching of the micro-grid, and the coordinated control between the renewable energy and the electric vehicle in the micro-grid is realized. Finally, the dynamic electricity price adjustment strategy is verified by building a microgrid simulation model, and the effectiveness of the strategy in microgrid operation optimization is verified by comparing the equivalent load and energy storage operation of the microgrid under the condition of disorderly charging and orderly charging and discharging of electric vehicles.
