Energy deviation penalty mechanism is an important part in the market-oriented electricity market and also a transitional stage before the formation of the electricity spot market. To express the impact of the deviation penalty on the sales revenue of retailers intuitively

a revenue-based corporate revenue model based on the penalty mechanism is constructed. Meanwhile

the demand response measures are adopted to reduce the amount of deviation electricity. An optimal purchase model of interruptible load contracts and spread options contracts is established with the goal of maximizing the sales revenue of retailers. Based on the transaction data of Guangdong power market in 2017

the impact of bundled contracts on the sale revenue of retailers is analyzed and the sensitivity analysis of monthly market price

user uniform price and compensation cost is carried out. The results show that retailers can reduce the appraisal cost by bundling contracts

then make the overall revenue increase and reduce the user's costs. In addition

the changes of monthly market price and compensation cost have the greatest impact on the deviation penalty

and the cost of retailers is most affected by user uniform price.
