Optimization and Economic Analysis of Multi-Park Microgrids Based on Wind-Solar-Storage Complementarity

Aiming at the optimal configuration of the wind-solar-storage complementary system of the multi-park microgrid, a multi-park joint operation model of wind-solar-storage complementary is established. The hybrid variable global optimization algorithm based on multi-dimensional and multi-scale is used to analyze the performance difference of the system after the energy storage is configured under the independent operation and joint operation modes of the park. According to the comparative analysis of the purchase power, abandonment power, power supply cost, power supply cost per unit power and average power supply cost under the two modes of independent operation and joint operation, it shows that the utilization rate of renewable energy under the joint operation mode is improved, the total cost is reduced, and the capacity demand of battery energy storage equipment is reduced, and the economy of system operation is improved.
