Abstract |
In the past decades, there has been a huge demand of energy requirements with respect to the increasing load demand and subsequent growth in the use of the renewable energy sources has increased from day to day to overcome the above crisis. Photovoltaic energy is one of these sources but due to its high cost and low conversion efficiency had limited the use of such endless energy source. Also the output power of a photovoltaic system (PV) is nonlinear and it is affected by variable weather conditions, therefore the maximum power point tracking (MPPT) was invented to extract the maximum power from each PV array to increase the cost effectiveness with increase in efficiency. In this paper an attempt has been made with two methods such as Perturb & Observe method (P&O) and modified perturb and observe method (MP&O) with fast tracking to increase the conversion efficiency of solar PV panels. In these techniques, from the available P-V curves the present value i.e, power and voltage, obtained is compared with the prior and post values for the above said methods. The performance of the modified P&O method is evaluated and compared with the P&O MPPT method. | |||||||||
