Just-in-time decision of demand respond based on complex event processing technology

As an important part of the smart grid, demand respond needs to be developed to meet the requirements of electricity consumption event online monitoring, real-time analysis and automatic response. Firstly, the typical demand response business models are designed and the online analysis context environments are ensuing determined. Then, a three layers framework of demand response just-in-time decision based on complex event processing technology is designed on the basis of the basic input/output event models and general operating rules. Finally, the rule of demand respond just-in-time decision technical in the auxiliary grid load shifting and regional load balancing is verified through intelligent electric equipment real-time operation control experiment. The experimental results show that the proposed technology is helpful to modify the load curve and reduce the peak-valley ratio.
