Transmission Expansion in an Open Access Environment: Reliability and Economics

输电扩建是一个全国性的重要领域，以确保可靠的电能供应，但它是严重不足的投资在美国根据北美电力可靠性理事会（NERC），“很少有大规模输电线路增加的计划;新的区域规划实体，适当的定价激励措施，以及改善，还必须制定简化的审批流程，以满足开放市场对新输电线路的需求。“在竞争激烈的环境下，独立系统运营商（ISO）（或区域输电组织（RTO））有责任维持互联电网的系统可靠性。ISO还运营电网并实施电能交易。然而，国际标准化组织并不投资于输电系统的扩建，而是由输电系统所有者等投资，我们提出了一个输电系统所有者收益的随机模型。我们将开发分析方法，根据成本和收入确定输电所有者愿意投资输电扩建项目的决策点。所提出的方法要求电力系统的优化，包括系统安全和阻塞的约束。这一建议的研究预计将产生影响的市场规则有关的传输扩展应该如何设计。由此产生的规则将在市场上提供必要的经济信号，以确保美国有足够的输电能力。

Transmission expansion is a nationally important area for reliable supply of electric energy and yet it is seriously under-invested in the U.S. According to North American Electric Reliability Council (NERC), '"very few bulk transmission line additions are planned; new regional planning entities, adequate pricing incentives, and improved, streamlined approval processes also must be developed to deal with the need for new transmission lines for an open market."In a competitive environment, the Independent System Operator (ISO) (or Regional Transmission Organization (RTO)) is charged with the responsibility to maintain the system reliability of an interconnected power grid. The ISO also operates the power grid and implements the transactions of electric energy. However, the ISO does not invest in the transmission expansion; the investors such as transmission owners do.We propose a stochastic model for the revenues of the transmission owners. We will develop analytical methods that determine the point of decision where a transmission own would be willing to invest in a transmission expansion project based on the costs and revenues. The proposed method requires power system optimization incorporating system security and congestion constraints.This proposed research is expected to make an impact on how the market rules concerning transmission expansion should be designed. The resulting rules would provide the necessary economic signals in the market in order to ensure an adequate level of transmission capacity in the U.S.
