文章建立了包括分布式光伏、负荷和换流站在内的规划模型。以交直流混合配电网扩展投资运行总费用最小为目标,建立满足节点电压、线路有功功率、分布式电源容量约束的数学模型;考虑负荷增长的需求,提出了改进GA的最小生成树规划方法,避免了不可行解,提高了优化效率;通过对分布式电源和交直流混合配电网进行选址定容和网架的综合优化,建立了考虑分布式能源综合利用的交直流混合配电网扩容优化方案。最后,采用对比分析,验证了文章所提规划方法的有效性。
Firstly, the total cost of investment and operation of the AC/DC hybrid distribution network is minimized, which satisfies the node voltage, line active power and distributed power capacity constraints. Mathematical model;then considering the demand of load growth, the minimum spanning tree planning method for improving GA is proposed, which avoids the infeasible solution and improves the optimization efficiency. Then, the distributed power supply and AC/DC hybrid distribution network are selected and fixed. With the comprehensive optimization of the grid, the expansion scheme of AC/DC hybrid distribution network considering the comprehensive utilization of distributed energy is established. Finally, the comparative analysis is used to verify the effectiveness of the proposed method.
