Identification of time elasticity of load based on analytic hierarchy process

Demand response is an effective measure to balance the load and generation. In this paper, time elasticity of load is proposed to evaluate the time selection of power consumption. It is obtained according to similarity between sampling load curve and typical load curve, smoothness of load curve, loss cost of load shift and proportion of load shift. Quantitative analysis of time elasticity of load is developed based on analytic hierarchy process (AHP). Case study demonstrates the effectiveness of the identification method.
