基于交叉联合供电的多配电台区网损优化

Line Loss Optimization of Multi-Distribution Transformer Bank Based on Interconnected Power Supply

低压台区配电变压器存在冗余度高、整体利用率低等缺陷。为优化配电网运行经济性,提高配电网设备利用效率,以多配电台区网损为目标函数,各运行条件为约束,建立一种基于交叉联合供电运行模式的网损优化模型,并采用粒子群算法对其进行求解。上海某实际配电网的算例分析表明,交叉联合供电模式可以有效降低台区网损,为社会带来巨大的经济效益。

In order to increase the utilization ratios of the distribution transformer banks in low voltage distribu- tion networks, an active line loss optimization model is proposed based on interconnected power supply, where the active line loss of multi-distribution transformer bank is set as the obiective function, several operating con- ditions are set as contraints. At last, a particle swarm optimization is utilized to solve the proposed model. The analysis on a real distribution network in Shanghai demonstrates that the interconnected power supply mode can reduce the active power loss and bring enormous profits to the society.
