| 中文摘要: |
| 为促进自备电厂参与电网互动，提出一种基于企业生产特性的自备电厂灵活性调节评估方法。根据企业生产流程中各环节不同的用电情况构建表征电力流通关系的生产特性矩阵，在此基础上分析自备电厂用电系统的灵活性。将自备电厂发电和用电系统等效为一个整体，提出分钟级和小时级两类灵活性评估指标，并以企业用电成本最低为目标，求解最优机组出力和负荷安排，从而对自备电厂灵活性调节能力进行评估。结果表明，该方法给出了自备电厂调节能力的量化评估结果，为推进自备电厂及其所属企业参与电网互动提供参考，并促进新能源消纳。 |

| In order to promote the self-supplied power plant to participate in the interaction of power grid, a flexible adjustment evaluation method based on the production characteristics of enterprises is proposed. According to the different power consumption of each link in the production process of the enterprise, the production characteristic matrix representing the power circulation relationship is constructed. On this basis, the flexibility of the power consumption system of the self -supplied power plant is analyzed.Equivalent to the power generation and power consumption system of the captive power plant as a whole, two kinds of flexibility evaluation indexes are put forward, including minute level and hour level. Taking the lowest power cost as the goal to solve the optimal unit output and load arrangement, the flexibility adjustment ability of the self -supplied power plant is evaluated. The results present that the method gives the quantitative evaluation results of self-sup-plied power plant regulation capacity, which provides reference for promoting self-supplied power plant and its affiliated enterprises to participate in grid interaction, as well as promotes new energy consumption. |
