摘要(Abstract)：

在省间电力市场实际运营中，应合理防范大电网安全运行风险，并最大化省间输电通道的利用效率。为此，建立了基于跨省跨区输电通道最大交易能力的省级电网双层博弈竞价模型。首先建立了考虑电网物理运行约束的跨省现货交易网络模型，进而提出输电通道最大可用容量优化方法。在此基础上，构建基于省间通道最大交易能力的双层购电博弈竞价模型。算例结果表明：所提优化方法能够有效协调电网安全与市场效率，显著提升省间通道的交易能力，避免省间潮流穿越和省内断面阻塞问题；双层博弈模型可得到纳什均衡下的最优购电报价策略，为市场主体决策提供参考。
In the actual operation of inter-provincial electricity markets, it is essential to reasonably prevent the operational security risks of large power grids while maximizing the utilization efficiency of inter-provincial transmission corridors. To this end, a bi-level game-theoretic bidding model for provincial power grids based on the maximum trading capacity of interprovincial and interregional transmission corridors is established. First, a interprovincial spot trading network model considering physical grid operation constraints is constructed, based on which an optimization method for the maximum available capacity of transmission corridors is proposed. On this basis, a bi-level game-theoretic bidding model for provincial grid power procurement based on the maximum trading capacity of transmission corridors is formulated. Simulation results demonstrate that the proposed optimization method effectively coordinates grid security and market efficiency, significantly enhances the trading capacity of interprovincial corridors, and avoids interprovincial transit power flows and intraprovincial interface congestion. Furthermore, the bilevel game-theoretic bidding model yields the optimal power purchase bidding strategy under Nash equilibrium, providing a decision-making reference for market participants.
