A Survey on Load Frequency Control (LFC) Problem in Hybrid Power System

In this paper, an ample literature survey on load–frequency control (LFC) problem in power system has been foreground. The different configurations of power system models and control techniques strategies that related to LFC problem have been considered in conventional as well as distribution generation-based power systems. Hybrid power system (HPS) consisting of multiple power generating units and energy storage units. Further, study on LFC challenges incorporating storage devices BESS/SMES, FACTS devices, wind–diesel and PV system etc have been discussed too.
