摘要: |
随着配电网中分布式电源渗透率的逐渐提高,对电网电压和网损的影响变得明显。这种影响和分布式电源规划的位置和容量密切相关。提出的时序分布式电源规划的方法:首先利用节点电压和网损综合敏感性分析,筛选出分布式电源的安装位置节点;然后利用优化方法对分布式电源容量优化。其中容量优化方法:以减少网络损耗和提高电压水平两个技术指标建立目标函数,利用机会约束规划方法构建约束条件;并使用蒙特卡洛模拟的方法对分布式电源和负荷时序模型进行随机潮流计算;最后利用精英策略的遗传算法求得分布式电源的最优配置容量。算例仿真结果验证了该规划方法的有效性。 |

Abstract: |
In the distribution network, with the permeability of distributed generator increasing, the influence on grid voltage and the network loss will become apparent. This effect is closely related to the location and capacity of distributed generator. A method of planning the timing distributed generator is proposed. First installation node of DG is selected by the comprehensive sensitivity analysis of node voltage and net loss, then optimization methods are used for distributed power capacity optimization. The optimization method is, establishing the objective function in order to reduce the network loss and improve the level of voltage, and establishing the conditions by chance constrained programming method; and doing random flow calculation by using the Monte-Carlo simulation method for random scheduling of DG and load; finally, the genetic algorithm of elitist strategy is employed to solve the model. Results verify the effectiveness of the method of site selection and capacity. |
