Abstract

Hybrid power systems (HPS) play an important role in places located far from electric grids. The sizing of these systems is difficult to determine due to the variable nature of renewable energy resources and the complex behaviour of their components. The battery bank has a significant impact on the performance of hybrid systems due to their complex behaviour and high investment costs. This situation has motivated the development of different approaches to improve the mathematical model of the lead acid battery. However, the accuracy of some of these approaches is still unclear. In this paper, using qualitative information about determined operating conditions, a small capacity hybrid power system installed in Zaragoza is analyzed, concluding that this information could be useful to HPS designers.
