基于网源协同的300MW 机组负荷快调及综合调频技术研究

大力发展新能源和大规模外电入鲁是山东实现新旧动能转换、推动经济快速平稳发展的关键之举,截至017年,新能源发电量和外电入鲁电量已占全省发电量的40.98％,到2018年风电和光电装机容量已达到千万千瓦 级别.但是,新能源受天气因素制约,一直处于随机波动状态,实时干扰电网频率,直接影响人民生活和工业生产, 甚至会产生弃风弃光事件;而特高压直流输电线路一旦出现故障,就会产生巨大供电缺口,导致电网频率突降,极有 可能引发大面积停电事故,造成重大经济损失和不良社会影响.因此,火电机组必须具备良好的一次调频和 AGC等 涉网性能,才能弥补新能源发电量波动和外电入鲁故障造成的频率波动,才能破解新能源消纳难题,为准确应对外电 故障提供数据支撑。     

Spherical fuzzy decision making method based on combined compromise solution for IIoT industry evaluation

The Industrial Internet of Things is crucial for enterprise and country to drive the strategic upgrade and raise the level of national intelligent manufacturing. When pondering the IIoT industry evaluation, the corresponding dominating issues involve numerous indeterminacies. Spherical fuzzy set, portrayed by memberships of positive, neutral and negative, is a more efficient methods of seizing indeterminacy. In this article, firstly, the fire-new spherical fuzzy score function is explored for solving some suspensive comparison issues. Moreover, the objective weight and combined weight are determined by Renyi entropy method and non-linear weighted comprehensive method, respectively. Later, the multi-criteria decision making method based on combined compromise solutionis developed under spherical fuzzy environment. Finally, the corresponding method is effectively validated by the issue of IIoT industry evaluation. The main characteristics of the presented algorithm are: (1) without counterintuitive phenomena; (2) no division or antilogarithm by zero problem; (3) no square root by negative number issue; (4) no violation of the original definition issue.
