Abstract: The details development of the battery energy storage system (BESS) model in MATLAB/Simulink is presented in this paper. A proposed logical-numerical modeling approach is used to model the BESS which eliminates the need of first principle derive mathematic equation, complex circuitry, control algorithm implementation and lengthy computation time. The proposed modeling method greatly simplified the modeling effort through simple logic and mathematic function. The application of the proposed BESS model is demonstrated using real commercial building recorded load profile through three case study applications which are peak shaving, load shifting, and load leveling. The BESS model is capable to generate details graphical information including load profile, peak demand without and with BESS and battery state of charge status for performance analysis. The BESS implementation and case study performed in this paper is fully reproducible. The proposed BESS model is applicable from LV distribution scale in kWh up to MV utility scale MWh storage applications. The proposed BESS model contributes as an indispensable tool for BESS implementation sizing determination and feasibility study.
