| 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: |
| ATC（Available Transfer Capability） is a technical index for evaluating the safety and stability of system operation and it is very significant of the reliability and economy of power system. Since the CBM（Capacity Benefit Margin） is a key factor directly affecting the accuracy of ATC，an accurate and feasible CBM calculation model is needed. The CBM calculation model is researched for the power system with large-scale wind power. Aiming at the intermittent disturbance of wind power，a probabilistic CBM calculation model based on LOLE（Loss Of Load Expectation，a reliability index） is proposed for the regional grid. For the multi-region grid，based on the calculated generation shortage of each region for a certain period，an optimal generation margin allocation model with the best economy as its objective is built for the units in a feeding region to further determine the CBM of each transmission section among regions. The calculative results for IEEE 30-bus system and IEEE 118-bus system verify the accuracy and effectiveness of the proposed model. |
