Abstract: India is country with abundant solar energy availability. The annual solar energy output exceeds the total energy output of India’s non renewable energy sources. As increasing installation of renewable energy sources into the grid. The fluctuations of power based on operating climate conditions like solar insulation and temperature is highly depends as it is not possible to limit such installations with time the penetration level of renewable sources will increase to meet demand with green energy. This paper proposed a flexibly power point tracking (FPPT) control of active power in photovoltaic system to achieve reserve capacity with Power Limiting Control (PLC) which will provide high stability to existing system without overloading it thus a proper integration to the grid and to mitigate adverse negative effects of high level integrations are possible with modified grid codes in stand of replacement of existing grid. Matlab/Simulink software package is used to make the model and effectiveness of the propose system is tested with Simulink environment. 
Keywords: Flexible Power Point Tracking, Maximum Power Point Tracking, Photovoltaic, Perturb and Observe, Power Limiting Control.
