摘要:
为克服传统配电网重构模型中将电缆载流量作为线路容量约束条件的不足,该文在电缆暂态热路模型基础上,分别以网损最小和维持供电的负荷量最大为目标,提出了计及电缆温度约束的配电网重构模型。该模型将线路容量约束改进为电缆运行温度约束,利用电缆温度裕量及其温升惯性过程充分挖掘线路供电能力,从而优化了配网重构决策,保证了配电网的节能与安全运行。
Abstract:
In order to overcome the shortcomings of taking the cable current carrying capacity as the line capacity constraint in the traditional distribution network reconstruction model,based on the cable transient thermal model,a distribution network reconstruction model taking the cable temperature constraints into consideration is proposed to minimize the network loss and maximize the load of the power supply in this paper. The model improves the line capacity constraint to the cable operating temperature constraint,so it can fully exploit the line power supply capacity by using the cable temperature margin and its temperature rise inertia process,thereby further optimizing the distribution network reconstruction decision and keeping the safety and economic operation of the distribution network to a greater extent.
