经济学家知道如何计算输电的最优价格。这些在实践中很少被应用。本文开发了一个13节点模型的传输系统在英格兰和威尔士，将损耗和传输约束。它解决了最优价格，并与统一的价格需求和发电，重新调度时，需要考虑到传输约束。从统一价格转向最优节点价格可以使发电商的福利增加1.3%的收入，并且不那么容易受到市场力量的影响。它还将发出更好的投资信号，但会造成政治上敏感的地区收益和损失。
Economists know how to calculate optimal prices for electricity transmission. These are rarely applied in practice. This paper develops a 13-node model of the transmission system in England and Wales, incorporating losses and transmission constraints. It is solved with optimal prices, and with uniform prices for demand and for generation, re-dispatching when needed to take account of transmission constraints. Moving from uniform prices to optimal nodal prices could raise welfare by 1.3% of the generators’ revenues, and would be less vulnerable to market power. It would also send better investment signals, but create politically sensitive regional gains and losses.
