OPTIMIZING POSITION AND INJECTING POWER OF THE PV SYSTEMS FOR POWER LOSS REDUCTION ON THE DISTRIBUTION POWER GRID

Abstract

The depletion of fossil energy sources leads to the prospect of widely installed solar power systems at commercial and residential loads in near future. As a result, voltage quality and power loss in the distribution grid can be negatively affected. This paper presents a solution using power loss adjusted sensitivity theory and genetic algorithm. The solution will identify some locations of solar power systems in the grid and calculate the generating power that needs to be adjusted in those systems over time. The results show that application of the proposed method reduces the amount of active power loss on the distribution grid by nearly 50% compared to when it is not applied. This result also shows that the solution meets the set goal and can contribute to the process of mass solar power installation at the loads in the future. In addition, overvoltage is also mitigated. The simulation was performed for the 22kV My Dinh distribution network in Hanoi, using the MATLAB 2016a software and the MatPower 7.1 library.
