The evaluation of power electronics has emerged since last few decades ago. In modern contest the world is moving from conventional energy sources to the renewable one. It is due to it greater abundance and environment friendly characteristics. Solar energy is one of the most promising renewable resources that can be used to produce electric energy through photovoltaic process. A significant advantage of photovoltaic (PV) systems is the use of the abundant and free energy from the sun. Power electronic devices used as interface between renewable power and its user. It makes the power generated by renewable sources suitable for utilization. Solar power contribution in power generation has been increasing very fast and cost of power generated by solar photovoltaic is falling rapidly. Solar photovoltaic cell converts solar energy directly into dc power. Power is mostly transmitted and utilized in ac form because of advantages associated with it. To convert the dc power into ac, a highly efficient converter is required for optimum utilization of energy. The MPPT algorithm uses the IPV and VPV of the PV array and gives the MPP and a VDCREF. This voltage is then passed on to the inverter and then further to the three-phase grid. In this paper the behavior of the active and reactive power of the grid which is supplied by the PV array is investigated. The various currents such as inverter current, grid current and load currents are also investigated.
