Peak load shaving in conventional electrical grids by small photovoltaic systems in sunny regions

This study suggests an efficient solution to the problems of peak load periods that occur during noon time in sunny regions. The idea of the solution is a simple one that depends upon the existence of relatively high sun irradiation during the period of peak load. Small decentralized grid-connected photovoltaic (PV) systems are to be installed on the roofs of the electrical consumers´ buildings so that they function as local generators of electrical power. Those systems will look nearly like the well known solar water-heating systems used widely in sunny regions. The approach, advantages and disadvantages of the high penetration use of such systems are presented in this study. Additionally, a cost calculation study of the PV systems and a feasibility study of their use is given.
