考虑风电发电的阻塞驱动输电网规划

Congestion-Driven Transmission Expansion Planning Considering Wind Power Generation in Spot Markets

Mohammd Hamdi

摘要:

大量大型风力发电机组的并网运行,给电网运营商在安全供电和能量调度优化方面带来了紧迫的技术挑战。本文提出了一个在电力市场环境下输电网规划的优化框架。网络中的拥塞程度被用作网络扩展需要的驱动信号。在阻塞成本和投资成本之间进行折衷,以确定最佳的扩展方案。长期网络扩展问题被形成为以下的解耦组合:1)主问题(受投资约束的投资成本的最小化和由操作问题(功率池)生成的Benders切割,以及2)操作问题,其解提供拥塞细节和相关联的乘数。建立了一个合适的电力池模型,并求解了阻塞成本、阻塞收益和输电影子价格。此外,我们建议使用一组指标来评估扩展对发电机,需求和整个系统的影响。该模型被应用到Garver六节点系统和IEEE 24节点可靠性测试系统。

英文摘要:

The integration of a massive number of large-scale wind turbines brought about urgent technical challenge to power transmission network operators in terms of secure power supply and energy dispatching optimization. In this paper, an optimal framework is proposed for transmission expansion planning in a deregulated power market environment. The level of congestion in the network is utilized as the driving signal for the need of network expansion. A compromise between the congestion cost and the investment cost is used to determine the optimal expansion scheme. The long-term network expansion problem is formed as the decoupled combination of: 1) the master problem (minimization of investment costs subject to investment constraints and the Benders cuts generated by the operational problem (power pool) and 2) the operational problem, whose solution provides congestion details and associated multipliers. A proper power-pool model is developed and solved for congestion cost, congestion revenue, and transmission shadow prices. Also, we proposed to use a set of metrics to rate the effect of the expansion on the generators, demands, and the system as a whole. The proposed model is applied to the Garver six-bus system and to the IEEE 24-bus Reliability Test System.
