Grid connected solar PV system with MPPT control using Advanced Controlling Techniques

Abstract

As the use of energy is increasing, the requirements for the quality of the supplied electrical energy are more tighten.
Energy is the most basic and essential of all resources. As conventional sources of energy are rapidly depleting and the cost of
energy is rising, photovoltaic energy becomes a promising alternative source. Photovoltaic (PV) generation is becoming
increasingly important as a renewable source since it exhibits a great many merit such as cleanness, little maintenance and no
noise. The output power of PV arrays is always changing with weather conditions, i.e., solar irradiation and atmospheric
temperature. Therefore, a Maximum Power Point Tracking (MPPT) control to extract maximum power from the PV arrays at real
time becomes indispensable in PV generation system. In recent years, a large number of techniques have been proposed for
tracking the maximum power point (MPP). MPPT is used in photovoltaic (PV) systems to maximize the photovoltaic array output
power, irrespective of the temperature and radiation conditions and of the load electrical characteristics the PV array output
power is used to directly control the dc/dc converter, thus reducing the complexity of the system. The resulting system has highefficiency. So here we going to study of different MPPT techniques then compare them and choose one of them for different
application according to their efficiency.
