Abstract

In the isolated micro-grid, frequency and voltage fluctuation are major problems because of the intermittent nature of renewable resources like wind and solar power. Our work focuses on frequency control of wind and photovoltaic(PV) based isolated micro-grid using traditional droop control technique. In this paper, a proportional resonant(PR) voltage and current controllers are designed to control the current and voltage output of the voltage source inverter(VSI) connected with dc battery. The traditional droop control method is applied to generate voltage and frequency reference set points for the VSI controller to control frequency and voltage of the micro-grid. The performance of the designed control system is conducted by two different case studies in order to observe the frequency control performance of the system.
