摘要

This work presents mathematical model of batteries AGM lead acid type that form part of a photovoltaic generating system. The proposed model allows estimation of the voltage of the battery and the state of charge with the objective of designing a controller to create greater duration, efficiency and autonomy of the system. Additionally, we present a mathematical model to estimate the useful life of the battery degraded due to corrosion, cycle, and the state of charge that permits evaluation of the loss of storage capacity in a general distribution scenario. Finally, experimental results and simulations obtained from the monitoring of a bank of batteries in a photovoltaic system are analyzed to validate the proposed model of state of charge. Furthermore, we will present the results of the evaluation of the useful life of the battery in two case studies in the framework of smart grid considering the functioning of a photovoltaic generator under different configurations.
