Abstract

In this paper, an overview is conducted on the prospected “net-zero” transmission network. A review of existing root-mean-square approach in voltage stability analysis is carried out in the first place. By introducing the control paradigms of converter control for modern and future sources of renewable energy and storages, limitations of root-mean-square has been discussed. After that, an electromagnetic approach in enhancing voltage stability is illustrated. With a case study of converter domination, a counter example is presented to showcase such electromagnetic enhancement can break through the Hoff bifurcation limit set by root-mean-square representation in voltage stability with single-infinite benchmark. Finally, it is concluded that converter domination can bring about better voltage security than state-of-the-art.
