| Summary: | Peak demand has been the main concern especially for commercial entities such as university campus. Peak demand in university campus usually occurs during the day when the ambient temperature is high, resulting in increased cooling requirements. The university power demand can reach up to 3257 kW which exceeds the average power demand that is normally 2974 kW in average. The aim of this project is to design a battery energy storage system (BESS) that helps to achieve peak shaving application and reduce electricity bills. Few aspects need to be considered in designing BESS for implementing the system in a university campus, which includes modelling of the BESS that consist of a battery and a three-phase converter and battery charging and discharging controller. The simulation of the BESS model is successfully implemented in MATLAB Simulink. The desired power needed to be shaved has been achieved and discussed further in results and discussions section. Peak power demand can be reduced by considering the topology for battery energy storage system and its controller. The peak demand of 283 kW can be supplied by the battery with the capacity of 3676.29 Ah. Calculations on the savings on peak demand charges show the reduction in electricity bill due to the BESS. The implementation of the BESS with the right capacity could reduce the peak demand by 39.11% |
