    摘要:

    随着我国能源需求和环保意识的提升,以风电、光伏等间歇式新能源为代表的绿色能源装机容量持续上升。大规模间歇式新能源消纳受电源、网架及负荷等多方面因素影响,为提升新能源的开发利用率,须采用合适的消纳评估方法对消纳情况进行分析。解析法反映了间歇式新能源消纳问题的本质,文中首先阐述解析法的数学模型,并结合解析法的运用对该方法进行评价。然后,梳理时序生产模拟法及随机生产模拟法的原理及运用情况,这2种方法是以解析法原理为基础,分别针对建模时对间歇式新能源消纳的时序特性、随机特性考虑不足而提出的改进方法,虽然这2种方法的运用仍存在各自的局限性,但相较于解析法,两者的求解精度均有了较大提升。最后,结合现有技术对未来间歇式新能源消纳评估方法研究进行展望,为评估方法建模、运用及改进等提供参考。

    Abstract:

    With the improvement of China's energy demand and environmental protection awareness,the installed capacity of green energy represented by intermittent renewable energy such as wind power and photovoltaics is visible in the upward trend. Large-scale intermittent renewable energy consumption is affected by many factors such as power supply,grid and load. In order to improve the development and utilization rate of renewable energy,appropriate consumption assessment methods should be used to analyze the consumption situation. The analytical method reflects the essence of the intermittent renewable energy consumption problem. The mathematical model of the analytical method is clarified firstly,and the method is assessed in combination with the application of the analytical method. Then,the principle and application of the time series production simulation method and the probabilistic production simulation method are sorted out. These two methods are based on the principle of the analytical method,and they are respectively proposed for the insufficient consideration of the time series characteristics and probabilistic characteristics of intermittent renewable energy consumption during modeling. Although the application of these two methods still has their own limitations,compared with the analytical method,the solution accuracy of the two methods has been greatly improved. Finally,combined with the existing technology,the future research on the assessment method of intermittent renewable energy consumption is prospected,which provides a reference for the modeling,application and improvement of the assessment method.
