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.

“…The results of the latter form inputs for the subsequent economic analyses. The analysis of the application of heat accumulation tanks on the economic efficiency of a CHP plant is presented e.g., in the following works [1][2][3][4][5][6][7][8][9][10][11][12]. The methodology for analyzing the economic efficiency of any investment processes applied so far was based on the discrete notation of the measure of NPV (Net Present Value):…”

“…The results of engineering criteria offer input values for the economic analysis. For example, the details of the increase in the electricity production ∆E accu el can be derived from the Equations (7) and (8) (Figure 4). The condition necessary for securing the economic profitability of the use of heat accumulation tanks in CHP plants can be limited to the condition that the revenues from the sales of the electricity generated in the peak load is at least not smaller from the increase of the cost associated with the construction of the heat accumulation tank.…”

This paper contains the results of a study in which a novel approach using continuous time notation was applied in the search for the optimum capacity of a heat accumulation tank to be combined with an existing CHP (combined heat and power) plant. The necessary condition associated with the economic profitability of the application of heat accumulation tanks in CHP plants is based on the condition that the profit from the exploitation of the modernized CHP plant does not decrease in relation to this profit before the process was initiated. Hence, the applied methodology provides a dependence that has universal application as it can be used to establish the optimal capacity of a heat accumulation tank suitable for any CHP plant design, i.e., for any thermal capacity of such a plant. The results also demonstrated that the specific enthalpies of the extracted steam before the base load heater and the maximum increase of the flow rate of the extracted steam feeding the base load heater in winter form the only necessary inputs for such calculations. The construction of the heat accumulation tank is only profitable for the case when the difference in the purchase prices at the times corresponding to peak load and base load electricity demand is sufficiently high.
