摘要：Electrical Power System is always subjected to different loading conditions; most of the loads vary in an unbalanced manner. This load variation gives negative impact on the entire power system parameters. There are two conditions which always occur in the power plant; Light load and Peak load condition, out of which the peak load is more hazardous because it can cause system failure or blackouts. Usually at the time of designing any system, primary source must be compatible to provide peak demand even though it occurs only for few seconds or minutes. Standardizing the whole system based on the peak demand goes underutilized most of the times, besides being costly but if we design system of storing electrical energy from primary source at some other energy storage device and then delivering that stored energy to meet the enhanced load in a controlled manner whenever peak demand occurs for a period of time ranging from a fraction of second to several minutes, we can improve operation of system significantly. In this paper a Super Capacitor Based Energy Storage System is used for maintaining constant frequency as well as mitigation of voltage sags. Super capacitors offer high power density, fast transient response, low weight volume and low internal resistance which make them suitable for pulsed load application. This paper also presents a model of a 125KVA Generator set and a simple Super Capacitor energy storage system with a pulse load simulated in MATLAB/ SIMULINK".
