INTRODUCTION
Grid interconnection of photovoltaic (PV) power generation system has the advantage of more effective utilization of generated power. However, the technical requirements from both the utility power system grid side and the PV system side need to be satisfied to ensure the safety of the PV installer and the reliability of the utility grid. Clarifying the technical requirements for grid interconnection and solving the problems are therefore very important issues for widespread application of PV systems.
Grid interconnection of PV systems is accomplished through the inverter, which convert DC power generated from PV modules to AC power used for ordinary power supply for electrical equipments. Inverter system is therefore very important for grid connected PV systems.
Inverter technology is very important to have reliable and safety grid interconnection operation of PV system. It is also required to generate high quality power to AC utility system with reasonable cost. To meet with these requirements, up to date technologies of power electronics are applied for PV inverters. By means of high frequency switching of semiconductor devices with PWM (Pulse Width Modulation) technologies, high efficiency conversion with high power factor and low harmonic distortion power can be generated. Reduction of inverter system cost is to be accomplished.
The greatest influence on system cost is the amount of PV modules installed. Other factors include maximum power demand, location, type and quality of equipment, extent of automatic controls and metering, provision of suitable accommodation for equipment and the amount of wiring needed. The cost of grid connected PV systems varies considerably.
As day by day the demand of electricity is increased and that much demand cannot be meeting up by the conventional power plants. And also these plants create pollution. If we look at the nature of load demand curve it is found that demand is increased from morning for different causes like opening the shops, markets, schools, colleges, offices etc. and that increased demand remains up to around 5 pm. And from the study of PV system it is found that, it is very much ideal to meet that increased energy demand by using Grid Connected Photovoltaic System. That why we go for grid connected topology.
