The electric power system is facing increasing stress due to fundamental changes in both supply and demand technologies. An increasing reliance on electricity presents significant challenges for utilities, state-level decision makers, and other stakeholders, who must improve reliability and resilience while cost-effectively managing the fundamental changes required to meet the needs of a low-carbon, digital economy. The electric power system is currently undergoing significant changes in the sources we rely on to generate electricity, the means by which we receive electricity, and even in the ways we consume electricity.

The increased use of information technology (computers, digital control) and communication systems not only has created new markets for drives, e.g. disc drives but also enforces more electrical drives to be used in systems as actuators and mechatronic systems. Advanced technologies to plan, manage, monitor, and control electricity delivery are needed to enable safe and reliable two-way flow of electricity and information, support growing numbers of distributed energy resources, and support customers participating in electricity markets as both power suppliers and demand managers. Research, development, demonstration, and deployment opportunities exist to accomplish and develop the new system designs; develop software and visualization tools that use new data from transmission and distribution system devices for enhanced, real-time operations and control. Research material innovations and develop transmission and distribution component designs for higher performance, reliability, and resilience.

This book ‘Electrotechnical Systems’ provides the innovative information in modern electrical systems in power electronics, electrical drives, and systems for improving electrical energy production and distribution. It focuses on the research, development, demonstration, and deployment (RDD&D) needs to develop a modern electric power system. It reviews the present state of development of drive technology and probes into future application and technology trends.

The book serves as guiding tool for students, academic researchers, and practicing engineers to better understand the principles, features, and detailed functions of various electrical systems, such as electrical drives, power electronics, and systems for production and distribution of electrical energy.
