| 摘要: |
| 分析了输电投资决策过程，构建了包含阻塞指数、发电企业剩余及其改善程度、电力用户剩余及其改善程度、阻塞收益及其改善程度、全社会福利及其改善程度等输电市场投资评估指标，动态计算出节点电价，并通过“有无对比法”求解出不同市场主体的利益。通过IEEE 30节点系统的测算表明了输电投资对发电商、用户和整个社会剩余的影响，分析了不同投资规模情景下各市场主体投资效益的变化趋势及其影响因素，从而证明了该输电投资效益计算模型的可行性与有效性。 |

| Abstract: |
| The decision-making process of transmission investment is analyzed and the evaluation model is constructed，including congestion index，generator surplus and its improvement degree，customer surplus and its improvement degree，congestion revenue and its improvement degree，social welfare and its improvement degree，etc. The nodal prices are dynamically calculated and the benefit of each market entity is explained by the “with and without comparison method”. Case study of IEEE 30-bus system demonstrates the impact of transmission expansion on the generators，consumers and social welfare. The investment benefit variation trends in different investment scales and its influencing factors are analyzed for each investment entity，which verifies the feasibility and effectiveness of the evaluation model. |
