Renewable energy tends to replace natural resources like coal and fuel, nowadays research work is in progress on solar power utilization. To overcome the photovoltaic (PV) installation issue, building-integrated PV (BiPV) system has been introduced. Partial shading is major issue in BiPV system. In order to prevent this issue, an anti-parallel bypass diode is added across each panel/cell. But it results in multiple peaks p-v characteristics with respect to varying irradiations. To track global peak power among all other local peaks, a special control algorithm based on extreme seeking (ES) strategy with fractional order controller (FOC) is developed. The proposed control method increases the power generation and efficient tracking of maximum power at MPP.
