The energy allocation of the core enterprise in smart energy efficiency industrial park (SEEIP) plays an important role in the energy saving and consumption reduction of the circular economy of industrial clusters. A local smart energy network framework based on information communication technology (ICT)was proposed to build SEEIP and realize intelligent transform of the core enterprise energy system in the existing industrial parks. And the energy calculation mathematical model for various energy medium with different gradesof energy production module, energy conversion module and energy storage modulewas given. With an objective function considering economic costs and environmental impact, the SEEIP enterprise energy network system configuration was optimized. Moreover, an improved differential evolution algorithm (DE) combined with a database query technique was used to solve the mixed integer nonlinear programming (MINLP) optimization problem. And the optimal configuration scheme of enterprise energy supply system is determined, whichcan meet the demand of users'cold, heat and electricity load.
