Abstract

With the progress of time, the power network has been the basis of economic development. However, people have little knowledge of the controllability of the power network. This article will study eight power networks and compare the controllability of the power network in many aspects.

Highlights

  • Power network supports the development of modern society, almost all industrial and life are highly dependent on electricity

  • Professional researchers began to study from the complex power network, the main study of the topology analysis, the robustness of the power network and attack vulnerabilities, power cascades and other cascading failure mechanism

  • We use the controllability theory of the network to analyze the controllability of the network, the research objects include four node systems of IEEE standard test system, node system of North-East China (NEC) grid and node system of Middle China (MC), NEC and MC will adopt the connections and nodes above 220kv for modeling

Summary

Introduction

Power network supports the development of modern society, almost all industrial and life are highly dependent on electricity. Professional researchers began to study from the complex power network, the main study of the topology analysis, the robustness of the power network and attack vulnerabilities, power cascades and other cascading failure mechanism. We use the controllability theory of the network to analyze the controllability of the network, the research objects include four node systems of IEEE standard test system, node system of North-East China (NEC) grid and node system of Middle China (MC), NEC and MC will adopt the connections and nodes above 220kv for modeling. The controllability of the eight-power network is studied and compared with the controllability of ER stochastic networks, WS small world networks, NW small world networks, BA scale-free networks, configuration model (CM) After comparing, the influence of the main structural characteristics of power network on the controllability is studied
