The thermal energy storage (TES) technology is an effective method to enhance the planning and the economy of the combined heat and power (CHP) plants, while it has still not been broadly promoted in China. In this paper we firstly establish a mathematical model for a Chinese CHP plant with TES. Then the EnergyPRO software is used to find the optimum type of the TES tank in a three-tariff electricity pricing market and the operation strategy of the CHP plant with the selected TES tank is studied. Thirdly, the economic benefits of the system with/without TES is evaluated. The results show that adding a TES tank with volume of 24000m3 can significantly increase operational profits of the CHP system and reduce the use of peak-shaving heat source.

In this paper, a new procedure has been introduced for optimal design of utility system in process industries. This method is based on the development of the R-curve concept by using estimation of costs, environmental impacts and exergoeconomic analysis. This new method can be applied for synthesis of site utility system in grassroot problems. In addition, the powerful and accurate cogeneration targeting method has been used. Also, the new graphical representations have been proposed. These curves are easy to be constructed simple to be understood. In this paper, optimal design of site utility has been carried out in the case study, in which the usefulness of this method is clearly demonstrated. The computer code has been provided based on new procedure to optimal design of site utility at fixed heat demand.
