This paper proposes a novel control system for a green renewable PV-powered standalone village with a hybrid type dc loads consists of variable resistive lighting, heating and motorized loads. A controller consisting of two different controllers is mainly used to regulate the DC-DC converter, to control power flow from PV-array modules and so to mainly track a given speed reference trajectory depicting the demand for discharge or flow, and also is especially utilized to provide minimum over current, inrush and ripple conditions, to decrease fluctuations and variations in the common DC bus, to make minimum DC bus content in bus voltage and current and also to prolong other power electronics equipments life with absorbing stresses. The proposed novel control scheme has been validated for both effective and good dynamical speed reference trajectory tracking with enhanced power utilization. The proposed control function is digitally simulated using the MATLAB/Simulink/SimPower System software environment. The dynamic performance of the system is examined for the control system validation.
