The total capacity of wind turbine generator systems (WTGSs) operating in the world reached 27 600 MW in Autumn 2002. In the European Union (EU) coun- tries, wind generators capacity of 20 500 MW were operational. Most of them were located in Germany (10 650 MW), Spain (4100 MW) and Denmark (2500 MW). The Danish electric power system has the largest ratio of the capacity of WTGSs to the capacity of all sources of energy and it reaches about 30%. The mean value of the rated power ofWTGSs sold in 2000 was 930 kW. Today, wind generators with a rated power equal to 2 MW have become standard. The...

The industry's widespread application of variable speed drives in the recent years accompanied by the electric utility's increasing use of capacitor banks have set the basis for paying considerable attention to the quality of electric power and seriously addressing the issue of current and voltage distortion, a major form of which is harmonic distortion. Harmonic studies are aimed at computing bus harmonic voltages, branch harmonic currents, and voltage and current total harmonic distortion (THD), as well as detecting resonance conditions. It is thus of great importance, when conducting...

In little more than a decade, the availability of nuclear power plants in the United States and most European and Pacific Rim countries has increased dramatically- from around 60% to about 90%. Such improvement is equivalent to adding approximately 30,000 MW e of new generating capacity in this period in the United States and perhaps an equal amount elsewhere. Some of this improvement has been due to longer fuel cycles-increases from 12 months to 18 or 24 months, but the major gains have been due to on-line maintenance and improved operation and planning by the utilities, accomplished...

Power electronics systems are physical devices that can be modelled mathematically as controlled dynamical systems. This makes them suitable for the application of existing control theory, particularly in the design of their regulatory subsystems. For years there has been a perceived need to bring the disciplines of power electronics and theoretical control into closer co-operation, demonstrating the potentially great advantages of, at first sight, rather obscure control theory to power specialists while making control technicians better aware of the fundamental needs and limitations of...

This book examines transmission grid security analysis using probabilistic safety assessment and taking into account power system dynamics after severe faults. Shows how to estimate consequences of grid faults and how to identify events that can lead to blackouts.

"Hydrogen-based Autonomous Power Systems" analyses the introduction of hydrogen energy technologies in autonomous power systems based on renewable energy sources (RES). The book contains a review of hydrogen technologies suitable for RES-based autonomous power systems, presents already-existing demonstration hydrogen-based power systems, and provides concrete examples for the integration of hydrogen technologies into existing autonomous power systems. Technical and economic analyses of hydrogen-based power systems are included, with illustrations and graphs, which are a useful tool for...

A mobile agent is a software program with the capability to suspend its execution and resume it on another computer. Agents are a relatively recent development in computer science, which have become a popular and useful methodology for the modelling and implementation of distributed systems, particularly those consisting of a number of largely autonomous components. The extensive use of multi-agent systems in various areas including information management, industrial control and manufacturing systems, suggests that the multi-agent systems methodology may also be appropriate for the design...

This monograph covers the area of vector control of three-phase AC machines, in particular induction motors with squirrel-cage rotor (IM), permanent excited synchronous motors (PMSM) and doubly-fed induction machines (DFIM), from the viewpoint of the practical design and development. Main focus is on the application of the IM and the PMSM in electrical drive systems, where the method of the field-orientated control has been successfully established in the practice, and on the use of the grid voltage orientated controlled DFIM in the wind power plants. After a summary of the basic...

This highly experienced author sets out to build a bridge between two inter-disciplinary power engineering practices. The book looks into two major fields used in modern power systems: intelligent systems and the signal processing. The intelligent systems section comprises fuzzy logic, neural network and support vector machine. The author looks at relevant theories on the topics without assuming much particular background. Following the theoretical basics, he studies their applications in various problems in power engineering, like, load forecasting, phase balancing, or disturbance...
