Abstract

In the future, Distribution network will face many challenges due to increased acceptance of renewable resources such as photovoltaic (PV)and wind power. Typical problems that arise from increased penetration of renewable resources include overvoltage issues, load imbalances on each feeder, and fluctuations in power output. In this paper, we consider installing Soft-Open Points (SOPs) to solve these problems. SOP is a power electronic device installed at the normally-open point (NOP) of the distribution network. Typically, SOPs are comprised of voltage source converters (VSCs), which can control the power flow between the feeders. In this paper, we discuss the method of calculating the optimal operating point of a SOP using the Particle-Swarm Optimization (PSO) algorithm using the characteristics of the SOP that can independently control the active and reactive power flows. The IEEE-33 bus test system was modified to verify the proposed method and the objective function for the bus voltage deviation and the index for the total line losses can be minimized simultaneously by using the PSO algorithm to optimize the multiple objective function Algorithm.
