Frequency Regulation in presence of PV-generation using Robust Control Theory

Inevitable energy oscillations due to presence of renewable energies cause frequency variation in smart grids. This paper suggests a novel load-frequency control method based on robust control theory. Proposed controller regulates the frequency of the system by giving proper order to thermal units and determine the amount of their generated power to compensate PV power oscillations. This method applied to a five-bus system, including a PV generation and three typical thermal units. The validity of this method evaluated by computer simulation analyses using MATLAB Simulink
