Abstract

A large proportion of power loss in distribution system is from transformer, which is not considered in the traditional Distribution network Reactive Power Optimization (DRPO). This paper proposes a DRPO model considering the power loss of transformer. The optimization method includes reactive power compensation with capacitor, tap adjusting with On-Load Tap Changer (OLTC) transformer. Simulation on the modified IEEE 33-bus test system with Differential Evolution Algorithm (DEA) is testified, the different load level is also analyzed and compared with the traditional optimization model, the test results show that the DRPO considering power loss of transformer is very necessary for light-loaded system. DRPO considering power loss of transformer is more reasonable and adaptable.
