中文摘要：
针对风电的多变性和不确定性（即间歇性）,以及火电机组组合结果在任一瞬间及各瞬间间牵制是否可行的问题,给出了风电范围、速率及速率变动的间歇性特征表达,推导出了火电机组组合应对该特征的必要条件,并就满足这一条件的能力给出评估方法,由此建立了新的机组组合数学模型,其核心在于能提供任一瞬间及各瞬间间牵制关系可行的机组组合解。基于该研究,可深入探讨机组组合与接纳风电之间的关系,分析在各类及苛刻情景下,机组组合接纳风电的能力及对应的经济规律。
英文摘要：
Variations and uncertainties in intermittent wind power generation lead to new challenges whether unit commitment schedule is feasible to cope with constraints at any time instant or time intervals. Considering this problem, intermittent uncertainties were expressed with wind power uncertainty range, variation speed and its acceleration. Then, essential conditions were deduced to accommodate intermittent uncertainties, with the power system ability to offer these evaluated conditions. At last, a new unit commitment model was proposed. Based on the proposed model, a feasible unit commitment schedule considering wind power intermittent uncertainties is provided. Furthermore, relationship between unit commitment schedule and wind power accommodation is discussed. Together with economic benefits, the system ability to accommodate wind power is also analyzed under different rigorous scenarios.
