Power Quality of Renewable Energy Systems Can Be Evaluated Using Simulation Data

The paper presents a comparative study of a renewable energy system using simulation data versus the data recorded for its implementation at the Hybrid Power System Test Bed (HPSTB) at the National Wind Technology Center, NREL. The simulation data were obtained from the model realized using RPM-SIM simulator. This study shows that under different conditions the power, voltage, and frequency traces of a simulated system follow closely those recorded. Consequently, it is concluded that the quality of power generated under different conditions can be evaluated using simulation data and that such simulation study can be used to develop the structure and control strategy of renewable energy system to meet power quality requirements.
