Demand Side Management and Economic Analysis Using Battery Storage System (BSS) and Solar Energy

Shortage of power generation results in unplanned load shedding. Active participation of the people on the demand side provides a solution by moving loads from peak time to off/peak hours during the day. This paper presents a Demand Side Management (DSM) that includes a rooftop photovoltaic system, a Battery Storage System (BSS), a hybrid control system, and a grid-tie inverter to reduce peak demands. The hybrid controller ensures that the maximum solar power generated is used or stored in the batteries for a given load, and any excess energy feeds the power grid. In this system, essential loads and generated power from rooftop PV systems are constantly monitored, and power generated by solar panels is preferred above grid electricity. According to the results, this system provides 100 % of each residence’s required energy, plus an annual 6497 kWh to feed the AC grid and store in the BSS, resulting in monthly cost savings and the elimination of peak loads, particularly during the summer months, as well as a variety of environmental benefits.
