What are the most profound changes you have seen in your field across your career?
Reliability is an old concept and a new discipline of engineering and technology. Reliability theory, as an extension of probability theory, was first applied in electronics, nuclear, and space industries after the Second World War, where high reliability was required for these increasingly complex systems. The beginnings of the developments of reliability theory can be traced back to the days of the Second World War. The first formal reliability evaluation was reported to occur when an explanation was sought for the poor performance of the German V-1 and V-2 missiles. These were constructed of a large number of components considered highly reliable. The reliability theory developed mainly applied to these specific fields. Since the first failure is most important in such an application, the theory idea of reliability was mainly developed for non-repairable systems. The development of reliability analysis methods for the repairable system was slow. Concurrently with the development of reliability aspects, an enormous amount of component failure data was collected, analyzed, and published in electronics engineering. Nowadays, reliability studies are performed in almost all engineering branches. Such studies evolve applications for both repairable and non-repairable systems in all areas. Reliability Evaluation of Power Systems has evolved from our deep interest in education and long-standing involvement in quantitative reliability evaluation and application of probability techniques to power system problems. Whenever reliability of a component, device, and system affects human life, the reliability problem usually becomes part of a large issue known as safety considerations. The reliability considerations are important factors in any engineering design and such considerations evaluate system usefulness or goodness, accounting the required constraints imposed on the system, one of the important constraints as the cost of the system. This might be the operating cost or planning cost including initial investment. The reliability analysis must also include factors like operating environment, time of operation, and quality of service rendered by the system. Power generation, transmission, and distribution are continuously gaining attention as crucial, empowering technology with a smart control approach to enhance the system’s reliability and efficiency. The challenges are solvable through modern power electronics with high flexibility, adjustable electronic loads, energy storage systems, and renewable energy systems including wind energy conversion systems, solar photovoltaic, electric vehicles, hydropower, and tidal power. The text of RAMPS is divided into six sections to address the modern issues of power system reliability. The first section describes the historical background, reliability principles, and comprehensive importance of reliability engineering; the second section addresses the design for reliability and design enhancement for dependability of modern power components and systems; the third section provides information about reliability assessment aspects for transmission system of modern power systems; the fourth section describes the reliability issues associated with conventional power distribution system; the fifth section of RAMPS illustrates the reliability analysis methodologies of modern distribution systems integrated with renewable energy systems; and the reliability analysis of power electronics components, integrated circuits and systems for modern power system applications are described in the sixth section.
What motivated you to write/edit the book Reliability Analysis of Modern Power Systems?
Reliability is an old concept and a new discipline in engineering and technology. Reliability Analysis of Modern Power Systems (RAMPS) has evolved from our deep interest in academics and innovative research and our long-standing involvement in quantitative reliability evaluation and application of probabilistic techniques to modern power system problems. Modern power systems have grown larger and spread over larger geographical area with many interconnections between neighboring systems and integration of renewable energy sources. The applications benefit society and solve power demand, power quality, reliability, generation, transmission, and distribution crises through modern power systems. The systems that involve high-risk and high-cost factors need to be reliable enough. This book is basically intended to present important aspects of reliability and its analysis in the field of modern power systems. The primary objective of RAMPS is to present the historical importance of reliability engineering, dependability assessment of power components, design enhancement for reliability, impact of renewable energy systems, and innovative research findings for engineering students, PhD research scholars, practicing power engineers, and technical managers.

What are the key challenges this audience faces?
The main problems related to reliability evaluation of component or system are lack of data, limitation of computational resources, lack of realistic reliability techniques, aversion to the use of probabilistic techniques, and a misunderstanding of the significance and meaning of probabilistic criteria and risk indices. Gathering and synthesizing information on power components, modern power systems and grid-integrated renewable energy systems is a challenge for students, researchers, designers, and industrial practitioners due to its complex nature, varying levels of detail, and potential difficulty in understanding. The young researchers and professional need a single source to learn the field, and a way to understand the art of real-time programming specific to reality. However, these challenges are not serious today since most utilities have valid and applicable data, IEEE reliability test systems, reliability evaluation techniques are very developed, and most engineers have a working understanding of probabilistic techniques.
How does your book solve these needs/challenges? Reliability Analysis of Modern Power Systems addresses the above challenges in comprehensive manners. The proposed book describes the content setting, formalization, and use of algorithms for assessing the reliability of modern, large, and complex electric power systems.
