摘要
工商业企业是能源消耗的主要群体,客观准确地评价其综合能源系统的价值是优化运行与能源审计的基础。传统的评价方法在促进多能互补、可再生能源消纳等方面存在不足。提出一种基于绿色㶲经济的综合能源系统价值评价方法,以企业能量平衡管理标准为基础进行客观定量计算,考虑产品单耗、综合能效、可再生能源利用率3项评价指标,采用模糊综合评价法,分别设计3项指标的隶属度函数及动态权重系数,得到综合价值评分,并以评分为依据选取最优运行方案。仿真结果表明,评价方法能够根据企业的用能规律选择合理的运行模式,促进能源的梯级利用及可再生能源的就地消纳,验证了方法的有效性和合理性。
Industrial and commercial enterprises are the main groups of energy consumption. The objective and accurate evaluation of the value of integrated energy system to industrial and commercial enterprises is the foundation of optimized operation and energy audit. Traditional methods have certain sufficiency in promoting multi-energy complementarity and renewable energy consumption. Thus, a value evaluation method of integrated energy system based on renewable exergy economy is proposed.Taking the management standard for enterprise energy balance as the basis to do the objective and quantitative calculation,considering three indices of product unit consumption, comprehensive energy efficiency and renewable energy utilization, and by using the fuzzy comprehensive evaluation method, the membership function and dynamic weight coefficients of three indices are designed to calculate the comprehensive value score, which is taken as a basis for choosing the optimal operation scheme. The simulation results show that the evaluation method can select a reasonable operation mode according to the energy consumption law of enterprises and effectively promote energy cascade utilization and local consumption of renewable energy, which verifies the effectiveness and rationality of the method.
