New Operating Paradigm for Electric Power Networks

最近开放输电网络以促进发电竞争和用户选择的举措引发了一场关于输电系统应如何重组以实现这一目标的辩论。这场辩论的对立双方现在通常被称为双边模式和联合模式。两种模式都采用传统的集中式操作来处理综合传输网的共享资源。传统的运营模式是在一个不同的时代发展起来的，因为电力公司是受监管的垄断企业。改组后的工业需要一种新的业务模式，以鼓励有效的竞争，同时保持必要的协调，以保证高标准的可靠性。协调并不意味着集中。协调确实有两个方面，即信息结构和决策权。我们建议沿着这两个维度来研究电力系统可靠（安全）和经济运行的新运行范式中的协调要求。认为系统运行的经济性决策机制与可靠性（安全性）决策机制应该分离。经济决策应由生产者和消费者之间的私人多边贸易来进行。通过电力系统运营者以合理的信息结构协调可靠性功能，引导发电商和用户在满足安全输电负荷限制的情况下进行有利可图的交易。将调查支持拟议模型所需的通信、计算和控制基础设施。＊＊＊

9527626 Wu Recent moves to open up electric power transmission networks to foster generation competition and customer choice have touched off a debate over how the transmission system should be restructured in order to meet the goal. the opposing sides of this debate are now commonly known as the bilateral model and the poolco model. Both models resort to conventional centralized operation in dealing with the shared resources of an integrated transmission network. The conventional operation paradigm was developed in a different era for electric utilities operated as regulated monopolies. A new operation paradigm is needed for a restructured industry that encourages efficient competition and at the same time maintains necessary coordination to guarantee a high standard of reliability. Coordination does not mean centralization. There are indeed two aspects of coordination, namely, information structure and decision-making authority. We propose to examine the requirements for coordination in the new operating paradigm for reliable (secure) and economic operation of power systems along these two dimensions. It is believed that the decision mechanism regarding economics and reliability (security) of system operation should be separated. Economic decision should be carried out by private multilateral trades among generators and consumers. The functions of reliability should be coordinated through the power system operator with proper information structure to guide generators and consumers to make profitable trades that meet the secure transmission loading limits. The communications, computing and control infrastructure necessary to support the proposed model will be investigated. ***
