摘要
基于分布式能源系统的主要设备建立不同能源系统,根据冷热电负荷需求、能源价格和设备技术信息等,运用非线性整数规划方法,建立分布式能源系统的优化模型。求解得到不同系统的最优配置、运行策略和评价指标值。建立分布式能源系统指标评价矩阵,利用信息熵原理求解不同指标的权重分布,结合专家评价方法确定的重要性指标权重,以此建立多指标的系统方案评价模型。计算结果表明光伏系统具有运行费用低、节能环保等优点,因此评估结果最优。
Based on the major equipment of distributed energy system（DES）,different energy systems were developed. using the demand of electricity,space heating,cooling and hot water loads,energy prices,and technical and financial information about optional technologies,a optimization model for DES was established by non-linear programming. The calculation results of the model was optimum configuration,optimal operation scheme and evaluation indicators matrix. The multi-criteria comprehensive evaluation method was introduced based on the principle of information entropy and expert assessment method to determine the weight distribution. The results demonstrate that photovoltaic system is optimal scheme on the account of lower operating cost,energy conservation and environmental protection.
