This paper explains how demand-side management techniques help in reducing the dependency of Baba Ghulam Shah Badshah University in India on grid power. Demand-side management techniques like load shifting, reduced energy consumption by using energy efficient devices, mitigating with the intermittent nature of wind and solar power are key for sustainable energy growth. As renewable energy sources are stochastic in nature, hence a stand-alone solar power plant will not be a reliable power source. In order to increase the reliability of solar power plants, they are integrated with grid and energy storage devices through proper power electronics interfacing. In this work, an integrated system consisting of grid, solar photovoltaic, battery storage and converters was developed. Power electronics converters are used, so that both A.C and D.C load demands can be satisfied. This paper presents the design and development procedure of simulation model for an integrated system. Simulation results show that energy consumption was reduced by the effective utilization of energy efficient techniques and the overall reliability of the integrated system has increased. The solar photovoltaic system was able to generate extra power during offload conditions, which could be stored or fed back into the grid, hence helping the utility to deal with peak load conditions and helping the university campus in generating the revenue from solar power.
