It shows a huge potential for demand side resources to participate in active power balance so as to improve the system capability of accommodating renewable generation; but it also brings additional complexity in system power balance control. Based on the contrastive analysis of wind power prediction error and the corresponding regulation ability of power grid in different time scales; a multi-time scale coordinated flexible load interaction response scheduling (FLIRS) was proposed. Firstly; an overall technical framework based on the principle of multi-level coordination and incremental refinement was presented. Load scheduling and regulation was divided into four time scales; i. e. a day-ahead 24-hour scheduling; an intra-day 1-hour scheduling; a 15-minute dispatch and a real-time dispatch. Secondly; several core models were built; including wind power prediction model considering uncertainty; multi-agent system (MAS) decision-making model and load dispatching control center decision model. Then; based on these models; a multi-time scale source-load coordination control strategy was established; and the load adjustment calculation method considering the uncertainty of wind power was also given. Finally; simulation results on a regional power grid show that the designed load scheduling models and strategies can fully take advantage of the flexibility of demand side resources at different time scales effectively. It will be beneficial for stabilizing wind power fluctuation and intermittence; as well as reducing system spinning reserve. © 2014 Chinese Society for Electrical Engineering;
