A Generalized MPPT Controlled DC-DC Boost Converter for PV System Connected to Utility Grid

This paper presents a Generalized MPPT control based DC-DC boost converter to generate continuous power with its preserved dynamic control system. The PV array is modeled with algebraic loop to achieve accurate solution with iterations in large sample of times. The larger time steps are utilized in this model to obtain fast simulation. MPPT controller embedded with Generalized P and O technique in PV system to regulate duty cycle through which maximum continuous power will be obtained. The MPPT controller with proposed converter is designed in a strategy to extract continuous power regardless of irradiance and temperature. 100kW PV array connected 25kV utility grid is examined in MATLAB SIMULINK and compared with other models in available literature to show effectiveness of designed model.
