New Operating Paradigm for Electric Power Networks

9527626吴最近开放电力传输网络以促进发电竞争和客户选择的举措引发了关于应如何重组传输系统以实现目标的争论。 这场辩论的对立双方现在通常被称为双边模式和联营模式。 这两种模型都采用传统的集中式操作来处理综合传输网络的共享资源。 传统的运营模式是在一个不同的时代发展起来的，电力公司作为受管制的垄断企业运营。 重组后的行业需要一种新的运营模式，鼓励有效竞争，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威。 我们建议检查协调的要求，在新的操作范例，可靠（安全）和经济运行的电力系统沿着这两个方面。 认为系统运行的经济性和可靠性（安全性）的决策机制应该分离。 经济决策应该由发电商和消费者之间的私人多边贸易进行。 电力系统运行者应通过适当的信息结构来协调可靠性的功能，以指导发电商和用户进行符合安全传输负荷限制的有利可图的交易。 通信，计算和控制基础设施，以支持拟议的模型将进行调查。 ***

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. ***
