摘要: |
提出了高比例清洁能源接入下计及需求响应的配电网重构方法。首先,以考虑网损成本、弃风弃光成本和开关操作惩罚成本的综合成本最小为目标,建立高比例清洁能源接入下计及需求响应的配电网重构模型。然后,针对配电网重构模型的非凸性,引入中间变量并对其进行二阶锥松弛,构建混合整数凸规划模型,使其能够在获得全局最优解的同时提高求解效率。最后,采用改进的IEEE 33节点配电网进行算例仿真,分析了需求响应措施和清洁能源渗透率对配电网重构结果的影响。算例结果表明,计及需求响应的配电网重构方法,可以有效提升清洁能源消纳能力,平移负荷峰谷差,提升运行经济性。 |

Abstract: |
A distribution network reconfiguration method with high penetration of clean energy considering demand-side response is proposed. First, the distribution network reconfiguration model with high penetration of clean energy considering demand-side response is established. Its objective function is to minimize the comprehensive cost including the costs of network loss, abandonment of wind power and photovoltaic power, and switching operation. Then, for a non-convex model of distribution network reconfiguration, a mixed integer convex programming model (MISOCP) is obtained by introducing intermediate variables and performing second-order cone relaxation. This can avoid the global optimal solution while improving the solving efficiency. Finally, case studies are carried out on the improved IEEE 33-bus distribution network, and the influence of demand-side response and clean energy penetration rates on the reconfiguration results is analyzed. The results show that the distribution network reconfiguration method considering demand-side response can effectively improve the clean energy consumption capacity, smooth the load peak-to-valley difference, and improve the economy of network operation.
