英文摘要：

The pressure of peak regulation in Guangdong power grid is increased rapidly. Analysis and utilization of demand-side response capacity （DSRC） is an important approach to tackle this problem. The three sources of DSRC, namely traditional DSM, consumer interaction using sma~ meters and electric vehicles penetration, are summarized. The influences of DSRC on load features are systematically analyzed in terms of load shaping, energy conservation and carbon-emission reduction. A multi-scenario calculation and comparison method is discussed using proposed mathematical model. Based on expectation in ＂12th-5＂ and ＂13th-5＂ plans, a quantitative assessment on DSRC of Guangdong power grid is performed.
