【摘要】：可用输电能力(ATC)是衡量系统安全稳定运行的技术指标,对于电网运行的可靠性和经济性具有重要的意义。容量效益裕度(CBM)作为直接影响ATC计算可信度的一个重要因素,需要构建更加合理、准确的计算模型。针对大规模风电并网后系统的CBM计算模型开展研究:首先,为应对风电间歇性扰动,提出基于可靠性指标(缺电时间期望指标)的区域电网CBM概率性计算模型;然后,对于多区域电网,计算出某时段各区域的缺电量后,以经济性最佳为目标,构建送电区域各机组发电裕度优化分配模型,进而确定区域间各输电断面CBM的大小;最后,以IEEE 30和IEEE 118节点系统为例分析验证了所构建模型的合理性和有效性。
[Abstract]:The available transmission capacity (ATC) is a technical index to measure the safe and stable operation of the system, which is of great significance to the reliability and economy of the power network operation. Capacity benefit margin (CBM), as an important factor that directly affects the reliability of ATC calculation, needs to build a more reasonable and accurate calculation model. The CBM calculation model of large-scale wind power grid connected system is studied. Firstly, in order to deal with the intermittent disturbance of wind power, a probabilistic calculation model of CBM is proposed based on reliability index (expectation index of lack of electricity time). For multi-area power network, after calculating the power shortage of each region in a certain period of time, the optimal distribution model of generating margin of each generating unit in the transmission area is constructed to determine the CBM size of each transmission section in the transmission area. Taking IEEE 30 and IEEE 118 bus systems as examples, the rationality and validity of the proposed model are verified.
