Optimal location and sizing of multiple PV systems in a distribution network using Marine Predators Algorithm

Optimal location and sizing of renewable energy sources (RES) represents an important instrument in the efficient operation and planning of the electric networks. Solar energy is the second most used RES after wind and it contributed as an important factor, in the last two decades, to improving the European energy supply security. The main purpose of this paper is to present a mathematical model for optimal location and sizing of multiple photovoltaic (PV) systems in a distribution network using Marine Predators Algorithm (MPA). The objective function consists in minimizing the active power losses, while maintaining all bus voltages and line currents within the acceptable range. Multiple scenarios are considered in order to integrate the daily and seasonal variations of both PV output and load demand. Finally, the solution with the lowest active power losses for a one-year period is selected. The results provided by the MPA are compared, in terms of performance with those supplied by a genetic algorithm (GA).
