Abstract
Increasing penetration of distributed generation (DG) in distribution networks (DNs) may increase the voltage level beyond the statutory permit. Normally, DGs operate at unity power factor (UPF) and does not contribute to reactive power generation. In this work, the reactive power capability of DGs has been assessed to mitigate the overvoltage problem in DN due to increased penetration of DGs. Two objective functions, minimization of energy loss of a DN and minimization of average voltage deviation of all bus bars, are proposed by optimizing reactive power of DGs as control variables. It is shown that DGs with reactive power support can enhance the performance of DN. Particle swarm optimization with time series power flow solution is used to optimize the control variables of wind- and solar-based DGs.
