电力系统功率轨迹的连续时间边际定价

Continuous-time Marginal Pricing of Power Trajectories in Power Systems

Anna Scaglione

摘要:

在本文中,我们制定的经济调度(ED)问题在连续时间,并包括在它的斜坡约束推导出一个表达式的价格,反映了一些重要的跨时间约束的电力单位。考虑这个问题的动机是斜升资源的稀缺性以及由电力资源的可变性所激发的其日益增加的重要性,特别是由于太阳能的添加,这加剧了在清晨和傍晚时分对快速斜升单元的需求。我们发现,边际价格的解决方案可以通过欧拉-拉格朗日方程找到,我们认为,这个价格信号更好地反映了市场价值的电力在存在显着的斜坡净负荷。

英文摘要:

In this paper we formulate of the Economic Dispatch (ED) problem in Power Systems in continuous time and include in it ramping constraints to derive an expression of the price that reflects some important inter-temporal constraints of the power units. The motivation for looking at this problem is the scarcity of ramping resources and their increasing importance motivated by the variability of power resources, particularly due to the addition of solar power, which exacerbates the need of fast ramping units in the early morning and early evening hours. We show that the solution for the marginal price can be found through Euler-Lagrange equations and we argue that this price signal better reflects the market value of power in the presence of significant ramps in net-load.
