Abstract

Since the schedulable energy is not available in the independent microgrid, only the energy required by the non schedulable wind and solar energy is considered. Through the transfer and scheduling of schedulable loads, the mismatch between power generation and power consumption can be reduced or eliminated, so as to optimize the capacity of microgrid components and reduce the related costs. In addition, the influence of demand response on reducing generation loss is studied. The optimization results of whether the demand response is taken into account are compared, and the optimal configuration is determined for each case. The results show that the application of demand response reduces the number of cells, inverter and photovoltaic panel capacity, thereby reducing the total net present value cost. At the same time, the implementation of demand response reduces the peak load, improves the load coefficient and correlation coefficient, and verifies the effectiveness of the proposed model and method.
