Power Systems Resilience has always been a major challenge for the scientists and the engineers. However, in the recent years, the increased public solicitude for the resiliency of power systems and the resilience enhancement of cyber-physical systems used here has powerful motivated activities of the research and development in this field. More than 18,000 technical articles written in last decade and stored in Science Direct Elsevier database have Power Systems Resilience in their title, abstract, or list of keywords. Other 2000 are already published in 2018, so this interest will grow exponentially in next years. There were less than 1450 until 2000.

The aim behind this enormous progress is quite simple: both scientific and industry are involved in resilience enhancement of cyber-physical systems used for securing the critical infrastructure networks such as power systems.

The book generally explains the fundamentals and contemporary materials in Power Systems Resilience. It will be very efficient for electrical engineers to have the book which containing important subjects in considering modeling, analysis, and practice related to Power Systems Resilience. The book comprises knowledge and theoretical and practical issues as well as up to date contents in these issues and methods for controlling the reliabilities against attacks and risks in AC power systems.

Some textbooks and monographs are previously presented for people want to learn more on Power Systems Resilience. The worth of the present book is that it tries to put forward some practical ways for impact analysis of risk events on power system operation, bringing together the topics such resiliency, smart grid or microgrids, and cybersecurity, which are now more and more organized. The editors wisely designated the topics to be preserved, and the chapters written by well-recognized experts in the field are placed in four sections.

The book introduces the reader to the modeling, analysis, and operation of resilience networks, and optimal operations of microgrids. Then, the main subjects related to planning, attacks, and recovery in resilience systems are presented and explained. The last section presents new research solutions for challenging issues appeared in last years. The book also includes informative case studies and many instances.

The book can be used in the classroom, to teach Power Systems Resilience courses to graduate students, and be suggested as further reading to undergraduate students in engineering sciences. It will also be a valuable information resource for the researchers and engineers concerned by Power Systems Resilience issues or involved in the development of cybersecurity applications.

It is obvious that the electrical infrastructure, which is responsible for providing electricity to all other critical infrastructures, has an important place in the functioning and development of todays world, and this network is to be reliable and at the same time to operate safely. In last decade, the needs for electric energy and the technological developments have increased annually, but the fact that the raw or renewable energy sources cannot be actuated in the same way has made it necessary to optimize their use. The power plants are dispersed in different regions and the optimum operation of the energy systems could be ensured by interconnection of these grid networks. Consequently, different problems arise during the planning and operation of microgrids, and the use of new technologies has become compulsory in order to solve the emerging problems, including enhance of Power Systems Resilience.

Resiliency and cybersecurity are two essential issues for todays power systems, but especially for smart grid or microgrids implemented in many developed countries. In the progress of power system components, one of the key aspects is to enhance their resilience in order to become more safety face to actual complex cyberattacks. The planning and operation of distribution network infrastructures all over the world are based on reliability principles of security and sufficiency. These principles enable distribution network to operate safety against common threats and as a result provide high-quality supply with few interruptions for consumers. However, it is evident that more considerations beyond the classical reliability are required to keep the lights on. Disruptive events, whether man-made or based on natural causes, can lead to component failures, and then breaking down the entire power system. The origin of the resiliency is word resilio, which mean the ability of an object to return to its original state. Here, the ability of power system to recover quickly after such destructive events is called as power system resilience.
