Abstract

The conventional evaluation methods of energy conservation and emission reduction lack the discussion of quantification index of energy conservation and emission reduction potential, and the evaluation effect is poor. Therefore, an evaluation method for energy conservation and emission reduction of distributed energy systems is proposed, which considers system dynamics and demand response. According to the requirements of system dynamics analysis, the relational variables in the system dynamics model are determined. The input-output relationship of energy saving, and emission reduction effect evaluation is described by system dynamics equation, and the input-output relationship of energy saving, and emission reduction effect evaluation is determined. Based on the maximum profit objective function and the minimum cost objective function of the user, the continuum equation of the medium transmission process in the distributed energy system is obtained. The evaluation indexes of energy saving, and emission reduction effect are selected from the three aspects of power consumption side, power generation side and the system itself to realize the evaluation of energy saving and emission reduction effect. The experimental results show that the evaluation curve obtained by this method is basically consistent with the actual curve, and the evaluation accuracy is high.

分布式能源系统节能减排效果评估

传统的节能减排评价方法缺乏对节能减排潜力量化指标的探讨，评价效果较差。因此，提出了一种考虑系统动力学和需求响应的分布式能源系统节能减排评价方法。根据系统动力学分析的要求，确定系统动力学模型中的关系变量。用系统动力学方程描述节能减排效果评价的投入产出关系，确定节能减排效果评价的投入产出关系。根据用户的最大利润目标函数和最小成本目标函数，得到分布式能源系统中介质传输过程的连续方程。从用电侧、发电侧和系统自身三个方面选取节能减排效果评价指标，实现节能减排效果评价。实验结果表明，该方法得到的评价曲线与实际曲线基本一致，评价精度较高。

期刊介绍： The Environmental Engineering Research (EER) is published quarterly by the Korean Society of Environmental Engineers (KSEE). The EER covers a broad spectrum of the science and technology of air, soil, and water management while emphasizing scientific and engineering solutions to environmental issues encountered in industrialization and urbanization. Particularly, interdisciplinary topics and multi-regional/global impacts (including eco-system and human health) of environmental pollution as well as scientific and engineering aspects of novel technologies are considered favorably. The scope of the Journal includes the following areas, but is not limited to: 1. Atmospheric Environment & Climate Change: Global and local climate change, greenhouse gas control, and air quality modeling. 2. Renewable Energy & Waste Management: Energy recovery from waste, incineration, landfill, and green energy. 3. Environmental Biotechnology & Ecology: Nano-biosensor, environmental genomics, bioenergy, and environmental eco-engineering. 4. Physical & Chemical Technology: Membrane technology and advanced oxidation. 5. Environmental System Engineering: Seawater desalination, ICA (instrument, control, and automation), and water reuse. 6. Environmental Health & Toxicology: Micropollutants, hazardous materials, ecotoxicity, and environmental risk assessment.
