A Survey on Theory and Practice of Automated Demand Response

Automated demand response(ADR) is one of the core technical functions of smart grids,however,as for ADR itself and its important role in smart grid there is large gap in both academic researches and engineering practices home and abroad.Independent of any manual operation,ADR can obviously improve timeliness,reliability and flexibility as well as cost-effectiveness of demand response(DR).ADR subverts the traditional understanding of DR and expands main functions of DR from optimizing power allocation to providing real-time auxiliary services to power system,thus ADR is really brought DR into the field of real-time dispatching,fully utilizes real-time adjustable potential of power load,tremendously enhances the connecting-ability of Intermittent energy sources and secure and stable operation capability of power grids.In this paper the supporting role of smart grid technology to ADR functions is discussed and based on international investigation the research items,standards and pilot projects related to ADR are introduced.Finally,existing obstacles to the implementation of ADR in China are analyzed,and the huge potential and development trend of carrying out ADR in China are pointed out.
