Load shifting is the main objective of demand-side management, and TOU is an effective measure to motivate users to participate in load shifting. Due to the operating characteristics of combined cooling heating and power (CCHP) system, the bidirectional peak-valley pricing for it will be more effective, motivating it to get a good economy, and changing its scheme of energy supply and trade of purchase and sale electric energy, thereby the daily load curve connected to bus changes. An error based on the least squares method is used to depict the relative value of the deviation from mean value of daily load, and the rate of change of the error is defined as the load curve satisfaction; economic differences of CCHP are compared under the condition of uniform price and peak-valley price, and then CCHP satisfaction is defined. In order to comprehensively consider the effect of adjustment for CCHP system, pricing model of peak-valley is established with the aim of joint satisfaction of load curve and CCHP system. Simulation results show that the bidirectional peak-valley prices decision-made reasonable can promote the CCHP system to adjust dispatch schedule, and obtain improvement of load curve of substation bus. Comparing joint satisfaction model of TOU with different weights, the responses are more active and peak load shaving effects are more available.
