Dynamic Demand Response and control in Smart Grid Environment

Smart grid enables active participation by consumers which is known as Demand Response. In order to match the power demand and power supply, a new method for Dynamic Demand Control (DDC) with AGC in Smart Grid Environment is proposed. A load frequency control using DDC based on price signals was modeled in this study. When frequency decreases customers are charged for Unscheduled Interchange. The frequency deviation was compared with the frequency deviation obtained when generation control, using PI controller, alone was implemented for frequency control. Thus DDC alone is sufficient to maintain the system frequency, during small load variations. DDC will play a major role in reducing these losses caused to the GENCOs under a Smart Grid environment.
