Construction and Optimization of Local Smart Energy Network Framework for SEEIP Core Enterprise

智慧节能工业园区(SEEIP)的核心企业能源配置对产业集群的循环经济节能降耗具有重要作用。针对SEEIP建设与既有工业园区核心企业能源系统的智慧化改造,提出一种基于信息和通信技术(ICT)的局域智慧能源网络框架,并给出了能源生产模块、能源转换模块与能源蓄存模块中各种能源介质及品位的能量计算数学模型。以经济成本与环境影响为目标的函数,给出了SEEIP企业能源网络系统配置的优化模型,并采用改进的差异演化算法(DE)结合数据库查询技术求解该混合整数非线性规划(MINLP)优化问题,给出企业能源系统最佳配置方案,以满足用户冷、热、电需求。

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.
