Implementation of unit commitment algorithm: A comprehensive droop control technique to retain microgrid stability

Though natural droop control technique is a familiar technique to control the voltage and frequency droop in microgrid application, due to some limitations to handle different cases of application, at present time, it is not appreciable to the scientists and researchers world-wide and virtual droop control technique is developing into the most prominent control technique to regulate the frequency and voltage droop in smart grid system. In this paper, two distinct unit commitment strategies, one for islanded operation and another for grid-tied operation, are proposed for the natural gas generators backed microgrid arrangement to enhance the overall efficiency of the system and significantly scale down the fuel consumption. These novel control frameworks offer revamped implementation of renewable energy resources and minimization of the natural gas generator by using a unit commitment algorithm. Besides that, here, the virtual droop control is demonstrated for the grid tied operation of the microgrid arrangement. Furthermore, all the necessary algorithms are illustrated with proper schematics and the results are verified by Matlab simulations.
