Photovoltaic Array under Partial Shading Condition for Irrigation

Abstract

This paper discuss about the effect of partial shading on photovoltaic array and driving the dc-dc boost converter to track maximum power point (MPP ) by incremental conductance (INC) MPPT algorithm. The temperature, irradiance, shading and array configuration will greatly affect the Photovoltaic performance. The shading effect on photovoltaic panel are caused by passing clouds ,neighbouring trees, neighbouring buildings ,towers .The PV characteristic of Photovoltaic panel get more complex under partial shading condition. The P-V and I-V characteristic under nonuniform insolation are simulated in Matlab based on solar irradiance and cell temperature. The design and analysis are made simple and easy through Simscape package.
