Research on the reactive power control of grid-connected inverter of distributed generation system based on genetic algorithm

This paper presents a centralized reactive control scheme of grid-connected inverter of distributed generation system. The power electronics interface performs the optimal operation to extract the maximum active power, while it also plays a key role in reactive compensation systems. The active and reactive power decoupled control is researched first. For the minimum network loss, genetic algorithm is used in reactive power optimization problem. Two simulation results show that the method proposed is effective in reducing power losses while improving the voltage profiles.
