Optimal Design of PV/Wind/Battery Systems by Genetic Algorithms Considering the Effect of Charge Regulation

Hybrid power systems (HPS) play an important role in the social development of areas located far from the electric grid. The optimal sizing of these systems is difficult to determine due to the variable nature of renewable energy resources and the complex behavior of their components. An important device of HPS is the charge controller as it protects the battery bank against extreme operational conditions, directly affecting the acceptance of charge from the battery bank and consequently the ability of the system to store energy. This paper presents a study about optimization of stand-alone PV/wind/battery hybrid power systems based in a genetic algorithm that considers the effect of charge regulation in the energy capture of the battery bank.
