Optimized PID Based Load Frequency Control of a Hybrid Microgrid

S. M. Aminu^*, Y. Jibril, A. Abdulkarim, A.S. Abubakar

This research presents the development of an optimized PID based load frequency control of a hybrid microgrid. The micro-grid (MG) concept allows the renewable energy sources to operate in both synchronized grid and islanded/stand-alone mode. These modes of operations of the MG have made it smart, hence require intelligent coordinated control strat...
