| Abstract | A solar power based centralized and decentralized battery energy storage systems were developed to perform peak shaving and compare. In this study, the storage system selected was Lithium-Ion battery system as they are widely used in many areas and applications. The storage system only depends on solar power generated at the ridge of the user-house. When the batteries are fully charged and solar power is surplus, then the power can be supplied to the utility. The standard IEEE five bus system was integrated with the solar-pv power generation model combined with the Lithium-ion battery energy storage system. A complete model was built in MATLAB Simulink software. The specific models of centralized and decentralized battery energy storage systems were developed and simulated for the peak demand shaving for the domestic end-use customers. Peak demand shaving as the main objective, the simulation was conducted for daily load demand curve. A control logic that works based on the constraints was implemented. Solar-pv and battery storage models were sized based on the power demand data used and power limits assumed for the peak shaving. The performance of the centralized and decentralized battery systems was compared. The developed model was explained and results were discussed. |
