A new direct MPPT technique for grid-connected solar inverter

In the present scenario of world energy sector, necessity of a three-phase grid-interactive photovoltaic system which is simple, fast, cost-effective and efficient under all circumstances is felt. In this paper an attempt has been made to build a new simple, fast and efficient Maximum Power Point Tracking (MPPT) method that will not alter the characteristics of the taken inverter topology. The effectiveness of the developed method has been confirmed with the help of simulation results. The software tool used for necessary simulation is PSCAD/EMTDC.
