文中针对大规模电动汽车(EVs)接入微电网的分布式能源(DER)出力优化进行了研究。在(EVs)无序充电模型的基础上,提出了基于峰谷负荷的分段电价模型,考虑行驶需求时间共同影响,建立了EVs接入微电网的完全响应行为模型。对负荷进行分类建模,提出基于响应权重的常规负荷电价响应模型,并建立了基于经济成本权重的综合效益优化模型。在典型微电网中,通过改进遗传算法,在不同调度控制策略下计算得到系统的优化出力结果。通过对比不同模型下的出力结果,验证所提模型的正确性和有效性。
In this paper, distributed energy (DER) output optimization for large-scale electric vehicles (EVs) access to microgrids is studied. Based on the disorderly charging model of (EVs), a split-price model based on peak-valley load is proposed. Taking into account the impact of driving demand time, a complete response model of EVs access to microgrid is established. The model of load classification is proposed, and the conventional load response model based on response weight is proposed, and a comprehensive benefit optimization model based on economic cost weight is established. In a typical microgrid, the optimized output of the system is calculated under different scheduling control strategies by improving the genetic algorithm. By comparing the output results under different models, the correctness and validity of the proposed model are verified.
