摘要:

随着双碳目标的提出,风能、太阳能规模化发展和技术进步,新能源将迎来高速发展,而新能源消纳问题依然严峻,准确评估新能源消纳因素对指定有效的消纳措施具有重要意义。分析新能源消纳形式,建立新能源消纳影响因素贡献度评估模型,从贡献度量化指标分析主要因素;基于时序生产模拟计算各边界条件下新能源利用率,提出新能源影响因素敏感因子计算方法。以新疆电网新能源消纳为案例,采用所提评估方法,评估各影响因素敏感性。分析表明,负荷增长、外送能力提升、资源特性、装机规模及接入时序等多种因素均对新能源消纳有不同程度的影响。

Abstract:

With the introduction of carbon neutrality and carbon peak goals,the large-scale development of wind energy and solar energy,and technological progress,new energy will gradually replace fossil energy power generation as the dominant energy source.With further development,the problem of new energy consumption still exists.Analysis of the factors affecting the new energy consumption and the contribution and sensitivity of the main factors is of great significance.This paper proposes a new energy consumption influencing factor contribution evaluation model,analyzes the main factors from the contribution metrics; calculates the new energy utilization rate under each boundary condition based on time series production simulation,and establishes a new energy influencing factor sensitive factor calculation model.Taking Xinjiang Power Grid’s new energy consumption as a case,the evaluation method proposed in this paper is used to evaluate the sensitivity of various influencing factors.The analysis shows that various factors such as load growth,increase in delivery capacity,resource characteristics,installed capacity,and access timing all have varying degrees of impact on the consumption of new energy.

Key words: new energy accommodation, sensitive factor, contribution degree, chronological production simulation
