38　Study of battery charge/discharge control considering ambiguity using Fuzzy logic

Abstract

In this study, Fuzzy logic was applied to take into account the ambiguity of large and small labeling for the variables used to determine the amount of charge and discharge in the recharge/discharge control of storage batteries. The ratio of recharge/discharge to the available amount of recharge/discharge was output using the clear weather index, which indicates the degree of clear weather, and the remaining amount of storage batteries as input values. As a result, it was confirmed that the application of Fuzzy logic reduced the total amount of electricity exchanged with the grid.
