Abstract
In this paper, the power loss based on double line frequency voltage ripple (DLFVR) , steep solar radiation change and DLFVR , rapid DC load change and DLFVR, finite operating voltage scope and DLFVR, and comprehensive loss factor amalgamation has been analyzed and compared for grid connected solar photovoltaic (SPV) single stage and two stage system. The SPV system in single stage and double stage operating on Maximum power point fluctuated by these loss components. An additional maximum power point tracker used in double stage SPV system nullifies the effects of loss components but the tracker diminishes the system performance nearly about 2.5%. In grid connected SPV system with single stage, the power loss due to these loss components is also nearly 2.5% but this system has the merit of saving equipments and hence reduces the expenditure and under certain operating voltage scope, the overall system efficiency does not reduce more. This power loss comparison has been studied and reported in MATLAB simulation environment
