Abstract
With the increasing penetration of renewable energy and power electronic equipment, the characteristics of frequency in a power system have been significantly changed. This paper analyzes the space-time distribution of frequency in a renewable power system. Firstly, the frequency-response model is established for different types of renewable integrated multi-generator power systems. Next, quantitative indices for the evaluation of frequency distribution are presented. Then, with simulation studies, the characteristics of frequency responses in different types of grid are analyzed. Finally, the factors affecting the space-time distribution of frequency, including location of renewable generator, line reactance and location of disturbances, are investigated.
