| 摘要: |
| 伴随国家电网公司对富余可再生能源跨省区消纳的大力推进，受端电网接纳能力的精细化评估分析成为跨省区新能源消纳的核心问题，对此，基于三公调度模式下的安全约束经济调度优化技术，提出了采用多级协同方案的受端电网接纳能力评估分析方法。该方法构建了省级电网接纳能力评估分析、分中心接纳能力安全校核与校正和多回直流通道接纳能力评估分析模型。首先执行省级电网接纳能力评估分析，为分中心接纳能力评估分析提供边界条件。然后对分中心全网、单回直流通道或多回直流通道进行接纳能力有效性评估和安全校正，为国调中心跨省区现货交易出清提供可靠的边界条件。经过多场景算例和实用化运行的分析与验证，结果表明该方法可准确分析分中心全网、单回直流通道或多回直流通道等不同维度的新能源消纳能力，为跨省区现货交易的顺利进行提供了技术保障，实现了富余可再生能源跨省区最大消纳。 |

| Abstract: |
| With the State Grid Corporation of China’s vigorous promotion of the cross-provincial consumption of affluent renewable energy, the refined evaluation and analysis of receiving end power grid acceptance capacity has become the core issue of cross-provincial new energy consumption. In this regard, based on the SCED(Security Constrained Economic Dispatch) optimization technology under the three-public dispatch mode, a multi-level collaborative acceptance capability evaluation and analysis method of receiving end power grid is proposed. This method constructs models of a provincial power grid acceptance capability evaluation analysis, a sub-center acceptance capability safety check and correction and a multi-circuit DC acceptance capability evaluation analysis. Firstly, the provincial power grid acceptance capability evaluation analysis is performed to provide a boundary for the sub-center acceptance capability evaluation analysis. Then the effectiveness evaluation and safety correction of the acceptance capacity of the whole network of sub-centers, single-circuit DC or multi-circuit DC are carried out, which provides reliable boundary conditions for the clearing of cross-provincial spot transactions of the National Power Dispatching Communication Center. The multi-scenario example verification and practical operation results show that this method can accurately analyze the new energy consumption capacity of different dimensions such as the whole network of sub-centers, single-circuit DC or multi-circuit DC in the receiving end power grid. It provides technical guarantee for the successfully launch of cross-provincial spot transactions, and realizes the largest cross-provincial consumption of affluent renewable energy. |
