Research On Cold Storage Price Decision Based On Cost Benefit Theory

In the face of summer electricity demand in Beijing due to the air conditioner, the promotion of cold storage technology in Beijing is becoming more and more urgent. However, due to peak-valley difference of ordinary time of use price is too low, it is difficult to encourage consumer to change their behavior. Therefore, it is necessary to design price for cold storage project. Therefore, the following aspects of the paper were studied:First, according to the Beijing’s maximum load curve, the typical daily load curve, difference between peak and valley load data, the load characteristics were deeply analyzed. The effect of peak shaving by cold storage technology is introduced, and it will lead the positive effect of the cold storage price for the promotion of cold storage technology. By summarizing the experience of the cold storage technology at home and abroad and the theoretical research on the cold storage price, we provide the suggestions of cold storage price policy to Beijing.Second, by analyzing characteristics of cold storage system with different operation mode, we get the more suitable operation mode for cold storage system in Beijing. According to previous experience of price changes and the development, the paper puts forward the principle and design method which should be followed when cold storage price is made. Then determine to use the cost-benefit method to solve the problems. And multi-objective optimization method and the mixed integer programming method are introduced in this paper.Third established the cost and benefit model which is related to the four aspects of users, power companies, power plant and society, based on the cost-benefit theory. Conduct in-depth study about time of use price model. And design new cold storage consumer’s response model based on the consumer psychology and price theory. Propose the cold storage price model which target with consumer benefit and total social benefit, and constrain the model with cost-benefit theory.Finally, by solving single-objective and multi-objective optimization models with lingo, propose the price program that meets the development status of cold storage in Beijing. Then compare the advantages and disadvantages of different price program and give the suggestions. Finally apply the pricing scheme to the built users of cold storage, and analyze its economic benefits to prove the rationality of the model.According to the above research, the cold storage price program can effectively cut peak load, reduce the user’s electricity tariff and improve the efficiency of power production. Provides a technical reference to the cold energy price policy, which will be to implement in the future.
