论文摘要
交替的电流(AC)偶然受限的最佳功率流(CC-OPF)问题解决了发电不确定性下发电和交付的经济效率。由于可再生能源量大量,后者是现代电网的内在固有。尽管取得了学术上的成功,但AC CC-OPF问题是高度非线性和计算要求的,这限制了其实际影响。为了改善AC-OPF问题的复杂性/准确性权衡,本文提出了一种快速数据驱动的设置,该设置使用稀疏和混合的高斯流程(GP)框架,以模拟具有输入不确定性的功率流程方程。与最新方法相比,我们通过数值研究提倡通过数值研究的效率快两次,更准确的解决方案。
The alternating current (AC) chance-constrained optimal power flow (CC-OPF) problem addresses the economic efficiency of electricity generation and delivery under generation uncertainty. The latter is intrinsic to modern power grids because of the high amount of renewables. Despite its academic success, the AC CC-OPF problem is highly nonlinear and computationally demanding, which limits its practical impact. For improving the AC-OPF problem complexity/accuracy trade-off, the paper proposes a fast data-driven setup that uses the sparse and hybrid Gaussian processes (GP) framework to model the power flow equations with input uncertainty. We advocate the efficiency of the proposed approach by a numerical study over multiple IEEE test cases showing up to two times faster and more accurate solutions compared to the state-of-the-art methods.
