We have previously shown the implementation of the optimization and benefits of using the MPPT controller algorithm and physics-based battery model along with other microgrid components.3 In this talk, we will discuss some simple examples for microgrids as well as consider the model of battery as a pack, i.e. a set of cells in series and parallel with slight inherent variation in SoC and SoH. The results of the proposed approach are compared with the conventional control strategies and improvements in performance and speed are reported.
