A State Estimation Algorithm For Hybrid Ac/Dc Networks With Multi-Terminal Dc Grid
IEEE Conference Proceedings(2016)
摘要
Hybrid AC/DC grids have been recently proposed as an efficient solution to accommodate increasing amounts of renewable energy sources in future smart grids. Similarly to the traditional power systems, state estimation algorithms are necessary in AC/DC grids to acquire awareness about the operating conditions of the system and to enable proper operation of the control tools. This paper presents a state estimator tailored for hybrid AC/DC grids with multi-terminal dc grid configuration. The proposed estimator is based on a two-step algorithm, which uses the boundary results of the AC and the DC grid to enhance the accuracy of the estimation. Results on a simple test network are presented to show the validity of the proposed estimator and to highlight the inherent benefits.
