Analysis of Fuel Cell Based Time Delayed Load Frequency Control Having Energy Storage Systems

In this paper single area fuel cell based load frequency control (LFC) system is examined. This system has a battery energy storage system (BESS) and flywheel energy storage system (FESS). Due to communication components, communication time delay is often occurred in the LFC system in practice. For this reason, this delay is added to system model. In order to improve the system performances, fractional order proportional-integral-derivative PI

) controller is used and it is tuned via recently developed Equilibrium Optimizer (EO). The present study, three different analyzes are performed. First, effectiveness of proposed controller and method are compared with the literature. Second, impact of variations of communication time delays are analyzed. Finally, the impact of changing of system time constants are examined. Obtained results are shown that system performances have been improved. In addition, the effects of variations in time delay and time constants on the system are shown comparatively.
