Frequency restoration using Dynamic Demand Control under Smart Grid Environment

Abstract
Smart grid enables active participation by consumers in Demand Response. In order to match the power demand and power supply, Dynamic Demand Control (DDC) with AGC in Smart Grid Environment is used. A load frequency control using DDC, was modeled for a two area system in this study. The frequency deviation and tie line flow deviation was compared with the deviations obtained when generation control, using PI controller, alone was implemented for frequency control. The PI controller parameters in the new scheme are then optimized using Lyapunov technique. Thus DDC alone is required to maintain the system frequency, during small load variations. DDC will play a major role in the economic operation of GENCOs under a Smart Grid environment. © 2011 IEEE.
