Impact of Battery Aging Model in an Energy Management System for an Isolated Solar Microgrid

摘要

Battery aging is an important issue that should be considered in the battery modelling. This is paramount when the battery is part of an isolated microgrid, being this a component with an important investment and replacement cost. in this work, three published aging models are included in a microgrid Energy Management System (EMS) optimization problem. Then, the performance of each model is assessed. To analyze the impact of battery aging models in a microgrid EMS, the real data of components of the microgrid located in Huatacondo in the north of Chile are considered. The results show the economic benefits of including the battery aging model into the EMS. The EMS considering the Bo Zhao aging model has the best performance since the total operating costs is lower (10.61% savings) than the costs obtained on other cases (8.09% savings considering the Drouilhel model and 3.24% considering the Copetti and Chenlo model), as well as a lower loss of battery life overall.
