New Control Approach for Voltage and Frequency Regulation in Standalone Power Generation System based on Solar PV Array

In this paper new approach control for voltage, frequency, as well as, power quality improvement in standalone system, which is based on PV array is investigate. DC/DC boost converter and DC/AC inverter are controlled to get maximum power from PV array, and maintain constant voltage and frequency at the PCC respectively, using Perturbation and Observation (P&O) technique method and decoupled control, which is based on d-q reference frame .The proposed system is reinforced by dump load and battery, which are tied to the DC link, in order are to ensure stable operating and continuous power supply. The performance of the proposed scheme and their developed control algorithm simulation are carried out using Matlab/Simulink in the presence of different kind of loads, as well as, during climate conditions change.
