摘要:

将可再生能源纳入电网需要基于优化的控制方案,需要可靠的电网模型。传统的参数估计和优化控制往往是解耦的,这导致估计过程中系统的运行成本很高。本工作提出了一种方法,同时最大限度地减少电网运行成本和最佳估计线参数的方法的基础上的最优设计的实验。与标准最优潮流和最大似然估计相比,该方法大大降低了最优估计的成本,并提高了参数的精度。我们说明了所提出的方法在基准系统上的性能。

英文摘要:

The integration of renewables into electrical grids calls for optimization-based control schemes requiring reliable grid models. Classically, parameter estimation and optimization-based control is often decoupled, which leads to high system operation cost in the estimation procedure. The present work proposes a method for simultaneously minimizing grid operation cost and optimally estimating line parameters based on methods for the optimal design of experiments. This method leads to a substantial reduction in cost for optimal estimation and in higher accuracy in the parameters compared with standard Optimal Power Flow and maximum-likelihood estimation. We illustrate the performance of the proposed method on a benchmark system.
