Summary:Gas turbine is the core energy equipment of integrated energy system (IES), whose installation scheme not only influences the installed capacity of other energy equipment, but also directly affects the operation strategy of IES. Thus, this paper aims at the existing problems that only focus on the system installed capacity and ignore the gas turbine installation scheme when optimizing the operation strategy of IES, and proposes a planning method for IES based on gas turbine installed capacity optimization as well as establishes the optimization model of IES. The natural gas consumption coefficient and heat generation coefficient are introduced into the model to separate variables and simplify the variable efficiency characteristics of gas turbine. Meanwhile, the matching coefficient is also lead-in to obtain the installation scheme including installed number and installed capacity of gas turbine. Besides, taking the operating load rate of energy equipment as decision variables and under the constrict of energy balance, the optimal operation strategy of IES and the installation scheme of both gas turbine and non-gas turbine equipment can all be obtained with total cost, energy efficiency and carbon emission of IES as objective functions. Meanwhile, an industrial park is selected as a research case in this paper to verify the effectiveness of the method proposed in this paper. It is proved that the proposed method can collaboratively optimize the installation scheme of each energy equipment in IES, and provide theoretical reference for the planning and design of IES and its economic, efficient and low-carbon operation.
