用最优潮流分析实时电价下的传输拥挤管理

Transmission Congestion Management under Spot Pricing Based Electrical Market

研究了在电力市场联营交易模式下，采用节点实时电价机制时的传输拥挤管理问题．用基于最优潮流的节点实时电价算法及软件，分析了用户侧可中断供电管理和电网无功补偿设备对消除传输拥挤的作用，并与通过传输拥挤合同的管理方式进行了比较．对一个５ 节点简化系统的全面数值分析表明，所提模型和算法的实用性．

The transmission congestion management under spot pricing based poolco electrical market was studied. Using optimal power flow based spot price algorithm/software, the effect of the interruptible load management and the installation of shunt devices on handling the transmission congestion was analyzed, and then, an analysis was carried out in comparison with transmission congestion contract (TCC) based transmission congestion management strategy. The detailed numerical results of a 5 bus reduced system were given to demonstrate feasibility and validity of the proposed model and algorithm.
