Energy Storage Battery Bank system to reduce peak demand for domestic consumers

A.G.N. Madhuranga I.A. Premaratne

In the generation of electricity it is always challenging to supply the varying demand in a day. As base load power plants cater the power demand throughout the day, the peak power plants have to be operated only during the high demand time. Since the running cost of peak load power plants are extremely high compared to base load plants, the suppliers are always trying to reduce the peak load using many techniques. As in pumped storage hydro power plants, energy storage systems can absorb energy during the off peak time and supply the energy back to the system during peak time. In this research, the objective was to find a system that virtually acts like a pumped storage power plant at consumers' premise. It was found that using a battery bank, the energy can be stored and supplied to the premise to reduce the peak load. The feasibility study of the proposed system has been carried out and the results shows the storage system can reduce the peak load at the consumer premise and hence make and impact to reduce the peak load in a utility as well. By making the peak load reduced, it was proposed to reduce the toxic gas emission of peak load power plants.
