Robust Control of Multiterminal DC/AC Systems,

Abstract

The successful application of two terminal dc links suggests that even greater flexibility in power dispatch and enhancement in stability can be realized by a multiterminal dc (MTDC) system embedded in an interconnected ac grid. Several utilities are looking into the possibility of building MTDC systems by adding new terminals to the existing dc links or by connecting dc links that are located in close proximity. It is quite conceivable that MTDC will become a major part of our energy delivery system by the end of this century. The intent of this paper is to illustrate how the MTDC control problem can be analyzed from a physical viewpoint, and how the physical insights can be utilized to arrive at a reasonable, robust control design. The main emphasis is on robustness. Some of the latest results in robustness theory are used in the design stage as well as in analyzing the final design.
