This paper explains practical design principles to follow for networked protection and control systems. Proven cybersecurity best practices, system architectures, monitoring methods, and defense-in-depth techniques are described. The risks and proper mitigations are explained for many common problems, such as human error, malicious malware, and advanced nation-state zero-day attacks. The paper references...
This paper focuses on a possible evolution of the control architectures suitable for Integrated Power Systems in modern all-electric ships. In control systems there is a major trend in using information and telecommunication technology as general real-time operating systems and standard communication protocols. This trend leads a standardization at software and communication protocol level that is...
Grid interface units, namely inverters, can be used to function as primary controllers for distributed energy resources (DERs). To decrease the costs of the DERs integration in Smart Grids, two new functionalities added to the inverter are proposed in this paper. The first is the metering to count for the injected power into the grid and hence the inverter shares in business-related functions, which...
Data Synchronization is important in advanced application of Integrated Power System Power Management System. This issue compared the mostly time Synchronization protocols and proposed a data Synchronization collection method based IEEE1588. The theory of IEEE1588 protocol is introduced and the basic methods to control synchronization precision is analyzed. Then a synchronization measurement network...
Communication system in microgrid is very important to microgrid operation. Except for meeting the demand of reliability, it should fulfill the characteristics of plug and play, dispersion in distributed devices, and the need of data information in controlling. A constraint set and a common communication platform are designed considering architecture and control of microgrid. In the process of designing...

The requirements of transforming the centralized and one-way flow of control and information by energy service providers to the decentralized and two-way flow structure enabling plug-and-play are rapidly increasing. The importance of reliable, high-quality electrical power continues to grow as society enters into a new era of economics driven by digitally-based technologies. Enabling the digital economy...
This paper discusses the planning and development of student training and activities for the Powerline Communications Laboratory at the Technical Education Institute (TEI), Patras, Greece. Powerline communications is currently an active area of research and development that combines three separate specializations from the standard training of electrical engineers: communications, power, and control...
The following topics are dealt with: mobile and wireless communications; optical and photonic communications; antennas and wave propagation; microwave theory and techniques; computational electromagnetics; performance of computer networks; networking technologies, services and protocols; information system security and assurance; software engineering; education technology; intelligent systems; biomedical...
This paper discusses the evolution that has taken place in substation monitoring, control and protection systems over the past ten years. The architecture has changed from many electrical / mechanical devices to the broad scale use of intelligent electronic devices. System architecture has changed from many independent standalone systems to a single system that can serve the needs of many. The changes...
With the situation that electric power system is becoming highly automatic, various control equipment designed for each part of electric power system(such as power generating station, substation, transmission lines and etc.), and for the control and regulation of each controlled object(such as power, voltage, frequency, phase and etc) have been applied in electric power systems. With the electric...
Due to the deregulation of the energy industry, an aggressively competitive market has evolved, which in turn has pressurised many utility owners and manufacturers towards amalgamating intelligent electronic devices (IEDs) in the entire power network. This merger of IEDs communication mediums will harness the full potential of distributed functions as well as enhancing the automation of the overall...
The adoption of the substation automation (SA) technology for the grids and substations is been increasingly used by the different power utilities all over the world. The old systems are being replaced by these new technologies and this is almost made mandatory by the Regulatory authorities, fn the last couple of years most of the power distribution utilities in India have adapted state of the art...
