Abstract

Power system operation and control changes significantly with continuous increase of renewable energy-based power generations and usage of compensator devices. The uncertainties characteristic of renewable energy such as fluctuating condition of wind speed and solar irradiance result in fluctuating power injection to the power system. Moreover, in order to improve stable power injection and stability performance of interconnected power system with penetration of large-scale renewable based power generations, an interface equipment such as power electronic and compensator devices are critically required. Deployment of power electronic devices and compensator devices on the other hand, potentially lead to the occurrence of interaction among those devices namely harmonic resonance. Thigh frequency resonance might cause a failure to the system if it was not handled properly. A comprehensive analytical study is demanded to investigate the effect of increasing renewable energy penetration on harmonics resonance. It was clearly observed that higher values of compensator devices and power injection from renewable energy decreased the harmonics resonance and hence improved the power system stability performance.
