Abstract :

Abstract-Photovoltaic Cell (PV) is an environment friendly source for electric power generation. This is relatively costly as compared to the other available sources of energy. The maximum power point tracking (MPPT) for the PV system application provides PV generated power for all irradiation conditions to have the maximum output power. MPPT is important unit in photovoltaic power systems because it increases the system efficiency by increasing the output power. The perturb and observe (P&O) MPPT algorithm is the most commonly used method for tracking maximum power ,but it has some drawbacks such as the oscillation of the operating point around the maximum power point (MPP) at steady state which consumes a portion of the available energy. Also, the P&O algorithm can be confused due to the rapidly changing atmospheric conditions that can lead into unstable system. Incremental conductance algorithm, on the other hand, requires differentiation, division circuitry and a relatively complex decision making process, and therefore requires a more complex micro-controller with more memory. The above problem will be overcome by using novel algorithm for maximum power point tracking and also it can increase the speed, accuracy, and efficiency of the PV module.
