Application of Battery Energy Operated System to Isolated Power Distribution Systems

This paper deals with model of battery energy operated system for a 42.5kVA DG set using Simulink and Power System Block-set in MATLAB environment. Battery Energy Storage System (BESS) is employed for compensation along with a small synchronous generator of 42.5kVA capacity coupled to a diesel engine as a prime mover. The DG set feeds a wide variety of loads. The performance of the system is simulated for linear, non-linear balanced and unbalanced loads. Simulation results justify enhanced power quality of the system with BESS application.
