英文摘要：

The demand response optimization model under time-of-use pricing was presented. Its objective function expression included interruptible load benefits and shifting load benefits based on load transfer rate. The solving algorithms of the optimization equation was given. The results of example analysis showed that the demand response actions had remarkable effect in eliminating peak load and filling valley load as well as increasing customer benefits under time-of-use pricing.
