直接约束边际价格

Directly Constraining Marginal Prices

Kyri Baker

摘要:

传统的边际电价取决于与相关优化目标相关的对偶变量。特别地,在最优潮流领域中,价格表示在每个总线上提供额外的功率单位的成本;对于经济调度情况,对偶变量表示向整个系统提供额外的功率单位的成本。对偶变量对于许多附加任务是有用的,包括系统拥塞的分析和负载调整的成本的确定。在这封信中,从传统的最优潮流分析,它示出了相关的对偶变量的约束如何影响电力价格,允许市场设置和需求响应程序,接受投标和上限的个人价格。

英文摘要:

The marginal price of electricity traditionally depends on the dual variables associated with relevant optimization goals. Particularly, in the optimal power flow realm, prices represent the cost of supplying an additional unit of power at each bus; for the economic dispatch case, dual variables represent the cost of supplying an additional unit of power to the whole system. Dual variables are useful for many additional tasks, including the analysis of system congestion and the determination of the cost of load adjustments. In this letter, departing from conventional optimal power flow analysis, it is shown how constraints on relevant dual variables affect the prices of electricity, allowing for market settings and demand response programs that accept bids and caps on individual prices.
