| Sumario: | Distributed generation (DG) in radial distribution systems helps improving energy efficiency by reducing technical losses, which enhances power quality, improves reliability, decreases network congestion, and provides other benefits. Although DG must be useful in distribution systems with commercial losses, better relationships and solutions are necessary, especially those that include renewable sources. In this research, we used photovoltaic panels, wind turbines, and capacitors to evaluate the effects of compensating real and reactive power in distribution systems with a high percentage of commercial losses. As the search for the best place to compensate the network necessitates considering a combination of real power, reactive power, and nodes, we considered finding solutions using three metaheuristic algorithms: a genetic algorithm (GA), a particle swarm optimization (PSO), and a bat-inspired algorithm (BA). The main results showed that locating and sizing renewable-energy sources and capacitors, according to commercial losses, help reducing technical losses and power generation costs. Wind turbines reduced technical losses further because they had both the lowest investment costs and a large amount of available resources compared with the results obtained with photovoltaic panels, which showed only some technical loss reduction and a small increase in costs. The hybrid system also showed a good reduction, especially when fewer photovoltaic panels were used. |
