New demand response architecture for stabilization of power quality in smart grid

A real-time imbalance between demand and supply by consumers' unforeseen activity or wide penetration of renewable energy resources in the near future would considerably affect the power quality. Demand Response (DR) management in smart grid is imperative, as it can effectively shape the total load from the demand-side. This paper presents a new DR architecture by indirectly controlling smart devices in each home. The proposed architecture offers the advantages of less communication data, scalability, and being user friendly. The simulation results show that the proposed DR architecture is very effective in stabilization of power quality by reducing the change rate of total load.
