Information And Communication

The paper proposes an approach to risk assessment in the electric power system control to identify possible failures in the electric power system functioning caused by cyberattacks on SCADA systems and WAMS. There is a large number of information, hardware and software factors, which increase the automated dispatching control system vulnerability to cyberattacks. The study shows the influence of unforeseen cyber-incidents in the information and communication infrastructure on electric power systems through false control actions on their physical part. The effectiveness of the developed risk assessment approach is demonstrated by its performance under uncertainty.

The current problem of the selection of the electric power system control nodes, which can be used to solve multicriterial problems of the consumers reliable supply with the electric power of the necessary quality of maximum efficiency is investigated. At the same time, a new method of making decisions while choosing electric power system control nodes is proposed. It is necessary to take into account a set of different types of indicators which characterize different properties of these nodes.

Power System Control

This paper focused on power system security problems and proposed risk assessment and preventive control method of electric power system based on voltage risk. The method built up a system voltage risk indicators, and have system voltage risk identified through risk assessment, on this basis, reduced the risk of the system voltage by optimizing the control variables of the system, which of course can increase system security. Finally, Refers to a 5-node tests as examples to verify availability of this method.

In this chapter, an overview of electric power systems is presented. The purpose is to describe the structure and operation of the power system and its evolution to the new smart grids. The first section gives an introduction about the electric grid and its evolution. Then, there is a section with a brief description of the different components of the electric power system: generation, transmission, distribution, and consumption. The third section is related to power system control, explaining why control actions are necessary in the power system to maintain the balance between supply and consumption and to keep constant the system frequency (at 50 or 60 Hz). In order to understand future applications of electric vehicles, it is important to present a fourth section related to fundamentals of the electricity markets. The chapter finishes with a description of the future power systems with high penetration of intermittent renewable energies, energy storage capacity, active demand management, and integration with telecommunication infrastructure.
