Self-Healing In Smart Grid: A Review

Abstract

Today's power systems are based on Tesla's design principles developed in the 1880s and have evolved over time to become the current aspect. Although communication technology is developing very fast, the development of power systems has not been able to keep up with it. Because the structure of the power system used is generally far behind and is unable to respond the needs of the 21st century. With the rapid development of today's technology, it has become possible to make the electricity network better by utilizing the computer and network technologies in the electricity networks. Thus, the electricity networks will provide a sustainable, safe and uninterrupted energy to the consumers by providing bi-directional data and electricity flow. The grids that can do this are called smart grids. One of the most important features of smart grid is that; in the case of a possible outage or fault, self-healing by continuing to provide energy flow.The lower the self-healing time, the less energy will remain in the network and the less time the system will continue to work to renew itself. The methods and tools used to achieve this are discussed in this article.self-healing algorithms and their application areas were surveyed using publications between 2003 and 2017. In the concept of self-improvement, especially transmission, distribution, micro grids, transient stability and cyber attack are explained.
