Smart Grid is designed to integrate advanced communication/networking technologies into electrical power grids to make them ‘‘smarter’’. Current situation is that most of the blackouts and voltage sags could be prevented if we have better and faster communication devices and technologies for the electrical grid. In order to make the current electrical power grid a Smart Grid, the design and imp...

Smart Grid is a vague concept with little theoretical studies. We propose in this paper a state of the art on Smart Grids to clarify the concept and identify the important issues. This term refers to an electrical network integrating the behavior and actions of users. It uses new information and communication technologies and new services combining: monitoring, control, communication and self-h...

Now-a-days Smart Grid is becoming a key element of energy strategies. Several definitions are coming in different literature but the overall meaning of these different definitions are same. Smart Grid is an intelligent monitoring, control and self healing of an electrical system with the help of information (data) communication in between the end user or generating station and control room. Thi...

As much as possible, it is important that the smart grid is secure from cyber-attacks. A vital part of ensuring the security of smart grids is to perform a cybersecurity risk assessment that methodically examines the impact and likelihood of cyber-attacks. Based on the outcomes of a risk assessment, security requirements and controls can be determined that inform architectural choices and addre...

The Smart Grid aims at making the current energy grid more efficient and eco-friendly. The Smart Grid features an IT-layer, which allows communication between a multitude of stakeholders and will have to be integrated with other “smart” systems (e.g., smart factories or smart cities) to operate effectively. Thus, many participants will be involved and will exchange large volumes of data, leadin...

Smart grids allow automated meter readings and facilitate two-way communications between the smart meters and utility control centers. As the smart grid becomes more intelligent, it becomes increasingly vulnerable to cyberattacks. Smart grid security mainly focuses on mutual authentication and key management techniques. An impeding factor in grid security is the memory and processing constraint...

Smart grid has been introduced to address power distribution system challenges. In conventional power distribution systems, when a power outage happens, the maintenance team tries to find the outage cause and mitigate it. After this, some information is documented in a dataset called the outage dataset. If the team can estimate the outage cause before searching for it, the restoration time will...

The smart grid is widely considered as an efficient and intelligent power system. With the aid of communication technologies, the smart grid can enhance the efficiency and reliability of the grid system through intelligent energy management. However, with the development of new energy sources, storage and transmission technologies together with the heterogeneous architecture of the grid network...
