摘　　要：尖峰负荷的持续增长威胁了电网的安全稳定运行,而空调负荷是尖峰负荷的重要组成部分。空调负荷的能量存储及转化的特性已经使其成为最有需求响应潜力的负荷,通过合理的激励与控制,可以在不影响或者少影响用户的前提下削减尖峰负荷以维持电力供需平衡。利用消费者心理学理论描述电价与空调设定温度调整值之间的关系,利用空调负荷的等效热参数理论模型预估空调负荷运行基线,设计了针对空调聚合负荷的作用时段差别化尖峰电价机制。仿真算例首先对比了优化得出的作用时段差别化尖峰电价与传统尖峰电价的作用效果,证明了所提出优化模型的可行性;然后分析了不同的用户组成对作用时段差别化尖峰电价制定的影响,为作用时段差别化尖峰电价的实施提供参考依据。The continuous increase of peak load in China has threatened the safety and stability of power grid, and air-condition- ing load has become an important part of the peak load. The ability to store and transfer energy makes air - conditioning load the most potential load in the respect of demand response. By reasonable controlling air -conditioning load, peak load could be reduced and balance could be achieved between supply and demand at lower cost without affecting users’comfort. The relationship between the electricity price and the temperature set - point of air -conditioning was described by the consumer psychology theory, and the base- line model of the aggregated air-conditioning was built on the basis of equivalent thermal parameters(ETP) model. Then a new demand response program called progressive time-differentiated peak pric- ing (PTPP) for air -conditioning load was designed accordingly. At last, through simulation example, the implementation effect of the time-differentiated peak pricing with that of the conventional criti- cal peak pricing and proved the feasibility of the price mechanism was compared. The influence of different compositions of consum- ers on simulation results was analyzed, which provided the theoreti- cal basis and reference data for the practical implementation of PTPP.
