Optimal placement of Pv systems from the aspect of minimal power losses in distribution network based on genetic algorithm

Abstract

In this paper, an optimal placement of photovoltaic systems as a source of active power in radial distribution network is considered. The objective of this optimization problem is minimizing system losses and improving voltage profiles based on optimal placement and sizing of PV systems. The maximal installed capacity of PV systems in distribution network is predefined and must not be exceeded. The simulation is done for three different cases from the aspect of input data (characteristic days for each month, Monte Carlo simulation and whole year data). In this way, both consumption behavior and solar potential are considered in order to find optimal solution. Genetic Algorithm is implemented for the calculation of optimal solution.
