Exploration of Hot Issues on Demand Response in Smart Grids

Through price signals and incentive mechanisms, demand response programs can help construct a reliable, efficient and robust feedback mechanism for smart grid and power market operation. With the development of power markets and the upsurge of smart grids, various market-driven demand response programs have been established around the world. In this paper, the demand response theory and its application framework adapting to electricity markets and smart grids are established and studies on these topics are conducted. The relevant hot issues including program decision-making and risk management in smart grids are also explored, from which the function of demand response in improving the system security, reliability and economics is set forth from multiple aspects. The study concludes that novel demand response programs can further enhance the customers′ response capability, and are more supportive to safeguarding the system secure and economic operation.
