Frequency Regulation of Interconnected Power System in Perspective of Smart Grid Environment

Abstract

newline The integration of renewable energy sources and the increasing complexity of newlineinterconnected power systems face significant challenges to maintaining stable frequency newlineregulation in a grid. Traditional methods of frequency regulation, including governor newlinecontrol and load shedding, are reviewed, emphasizing their limitations in adapting to the newlinedynamic nature of modern power systems. The integration of renewable energy resources newlinein an interconnected power system may cause to frequency deviation problem if suitable newlinecontrol algorithm has not considered in the study. newlineReliable communication systems are essential for the proper functioning and newlinemonitoring of smart grid (SG). It is widely acknowledged that communication newlineinfrastructure particularly wireless networks are unreliable due to time delay, newlinecommunication failure and other factors. The majority of the novel challenges associated newlinewith achieving the intended objectives in the operation of interconnected power system newlinein perspective of SG cannot be accommodated by the traditional load frequency control, newlinewhich was initially designed to cater to the requirements of a regulated electricity sector. newlineDue to the aforementioned factors, these extant communication infrastructures are newlineincapable of supporting the implementation of modern control and protection schemes in newlinean interconnected power system. In a new environment, the challenge is to integrate newlinecontrol, communication, and computation into the operation and control functionalities newlineof power systems at the appropriate levels. As a consequence, there will be an escalation newlinein the rates of frequency variation, which will manifest in the intensity of frequency newlineexcursions that occur during power imbalance. Consequently, demand response (DR) and newlinemulti agent-based system controller could serve as an additional strategy to mitigate the newlineimpact of renewable energy resources interconnected power system on the inertial newlineresponse to the Load Frequency Control (LFC) problem. newlineIn the context of above-described research challenges
