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 smart 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.%广东电网的调峰压力日益严峻,分析并利用需求侧响应能力成为解决这一难题的重要途径.综合考虑传统需求侧管理、基于智能表计的用户互动及电动汽车并网运行,归纳总结出广东电网需求侧响应能力的潜在来源;从负荷整形、用户节能及低碳减排3个方面剖析需求侧响应对现有用电特性的影响.建立了支撑整体研究框架的数学模型;采用分场景对比测算的思路,结合广东电网“十二五”、“十三五”发展远景,针对其需求侧响应潜力做出了定量的评估分析.
