There is growing awareness towards cybersecurity threats in power systems. Deployment of more intelligent electronic devices (IEDs) and the communication lines increase the probability of such attacks. IEC 61850 standard facilitates communication between different IEDs and eases interoperable operation with set data and message structures. An unwanted consequence of this standardized communication over ethernet is increased viability to cyber threats. Replay and masquerade attacks are, especially, of concern due to their imminent impact on the operation. While detecting replay attacks is easier, since the original messages are used for the attack, masquerade attack messages may be difficult to distinguish from original ones. Furthermore, inadequate mitigation approaches may be tricked by the hackers and the system starts the attacker as the authentic sender and discards original messages from authentic sources. It is vital to develop an approach that incorporates message authentication. In this fashion, when the hackers modify the message contents to bypass security systems, the tampering can be detected, and the messages will be discarded. This paper analyses replay and masquerade attacks on IEC 61850 GOOSE messages and develops a solution to mitigates both of those. To detect modified messages, two distinct authentication mechanisms are utilized: RSA since it is the algorithm stipulated in IEC 62351-6 and Elliptic Curve Digital Signature Algorithm (ECDSA) due to its widespread use in smartgrid cybersecurity solutions. A full solution to mitigate GOOSE replay and masquerade attacks is developed based on the proposed framework in IEC 62351 standard. Full implementation is tested in the lab and results are included to show the viability of the solution.

“…Storage system employed in this scenario can be any of the ESS discussed in this paper. Standardized approach to control and communication has the benefit of interoperability and interchangeability, where different technologies from different manufacturers can be seamlessly integrated [218]. Accordingly, it is possible to use EVs and stationary battery storage systems as well as more innovative systems such as graphite or paper batteries.…”

It is an exciting time for power systems as there are many ground-breaking changes happening simultaneously. There is a global concensus in increasing the share of renewable energy-based generation in the overall mix, transitioning to a more environmental-friendly transportation with electric vehicles as well as liberalizing the electricity markets, much to the distaste of traditional utility companies. All of these changes are against the status quo and introduce new paradigms in the way the power systems operate. The generation penetrates distribution networks, renewables introduce intermittency, and liberalized markets need more competitive operation with the existing assets. All of these challenges require using some sort of storage device to develop viable power system operation solutions. There are different types of storage systems with different costs, operation characteristics, and potential applications. Understanding these is vital for the future design of power systems whether it be for short-term transient operation or long-term generation planning. In this paper, the state-of-the-art storage systems and their characteristics are thoroughly reviewed along with the cutting edge research prototypes. Based on their architectures, capacities, and operation characteristics, the potential application fields are identified. Finally, the research fields that are related to energy storage systems are studied with their impacts on the future of power systems.INDEX TERMS Storage systems, electric vehicles, power system optimization, market liberalization, renewable energy, new operation schemes, power system planning.

“…Similarly, the edges in graph G are mapped to the connections in electrical network. As an example, the electrical network shown in Figure 3b can be represented by a graph as shown in Figure 4 [6]. Proposed Solution: Any change in the electrical network maps to either addition of a new node in the graph, or a loss of an existing edge.…”

Unlike conventional grids, microgrids may utilize different connections and the overall topology can be variable. Considering this, it is required to develop a new protection concept/scheme for safe operation. Maintaining proper selective operation of the relays in these dynamic microgrid structures is a challenge itself. This requires monitoring the connections and updating time delays of the relays which will ensure the desired hierarchy in the system. In this paper, a novel approach has been taken where electrical networks are modeled according to graph theory. Smart algorithms, such as network graph discovery, local manager selection, and protection coordination strategy, are run to automatically detect topology changes and ensure proper protection operation. Furthermore, distributed nature of this method mitigates the risks associated with central controller-based schemes. The developed method is applicable to all power system operations, and it poses a unique implementation in postdisaster recovery. After a disaster or terror attack, this self-diagnosis, self-healing system can identify healthy sections and run them as a standalone system until the relief arrives. The ability of the protection system to be run as a distributed control makes sure that any healthy part of the system can be restructured and utilized, without the dependency, on any central controller or connection.
