Optimal location and sizing of photovoltaic systems in order to reduce power losses and voltage drops in the distribution grid

Abstract

The paper presents a method for the optimal allocation and sizing of photovoltaic systems in order to improve power quality in distribution grids. The proposed method is based on the Genetic Algorithm Matlab Toolbox application. The obtained results show that Genetic Algorithm is more accurate and convergence speed is higher than the algorithm used in DIGSILENT/Power factory software. In this way, the defined capacity and location of photovoltaic systems were checked through the performed simulations in DIGSILENT/Power factory software. The simulations were carried out with real data obtained from the Kosovo Distribution Grid. The results from the application of the proposed method showed reduced power losses and voltage drops in the distribution grid confirming the method validity.
