monthlyРrenewable energy schedule making and day-ahead and intraday rolling optimal dispatching.Based on the basic platform of smartРgrid dispatching and control system (D5000 platform ),a renewable energy dispatching technology supported system isРdeveloped.This system is able to realize coordinated optimized renewable energy dispatching of multi-time scale,whileРgradually reducing the impact of forecast error and ensuring the security modation of renewable energy.The researchРresults are in application in 16regional or provincial grids.Р This work is supported by National Key Technology R&D Program of China (No.2013BAA02B01 )and State GridРCorporation of China (No.NY71-14-038).Р Key words:renewable energy modation;optimizing dispatch;multi-time scale;dispatching and control systemsР 361
