在独立微电网中由于可调度能源不可用,仅考虑不可调度的风能和太阳能供应所需能量。通过可调度负荷的转移和调度来减少或消除发电与用电之间的不匹配,从而实现微电网组件容量优化和相关成本降低。此外,还研究需求响应对降低发电损失的影响。对是否计及需求响应两种情况的优化结果进行比较,对于每种情况确定了最佳配置。结果表明：需求响应的应用减少了电池数量、逆变器和光伏组件容量,从而降低了总净现值成本。同时,需求响应的实施降低了负荷峰值,提高了负荷系数和相关系数,验证了所提模型及方法的有效性。
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.
