Grid Operation

Smart grids are becoming increasingly popular thanks to their ability to operate with higher precision and smaller margins. Dynamic operation control in smart grids can be achieved with phasor measurement unit (PMU) based wide area monitoring and control systems. The data communication requirements for the PMU based applications are well addressed in the IEEE C37.118.2 and IEC 61850-90-5 standards. Due to the higher probability of cyberattacks and the scale of their impact, data security is a critical requirement in PMU communication networks. The IEC 61850-90-5 communication standard addresses this security concern and proposes the HMAC (hash based message authentication code) with key distribution center (KDC) scheme for achieving information authentication and integrity. However, these IEC 61850-90-5 security recommendations do not consider the mechanism for attacks such as man-in-the-middle (MITM) attacks during KDC key exchanges. MITM attacks can be easily implemented and may have a large impact on the grid operation. This paper proposed an explicit certificate-based authentication mechanism to mitigate MITM attacks in PMU communication networks. The proposed certificate-based authentication mechanisms were implemented in real-time using Python-based terminals to observe their performance with different signature algorithms.

The IEC 61850 standard originally was developed for the substation automation. During the past years it was adapted for the integration of distributed energy resources into communication networks, however, with specific requirements. Many small and midsize manufacturers are using, as controllers, a big variety of different microprocessors with limited performances. Such controllers need an interface for IEC 61850 communication networks with a basic functionality which can be implemented with limited costs. Based on their experiences during the realization of an IEC 61850 communication stack, the authors propose ways to support these requirements. In particular, communication interfaces for photovoltaics systems and wind power plants are considered.

The development of the Ukrainian electricity sector in terms of energy independence and energy saving is directly related to the introduction of so-called Smart Grid technologies — the construction of intelligent electrical networks. That, in turn, requires their automation, and first of all — electric substations, and, consequently, the introduction of a number of standards harmonized with international ones. Such standards are: IEC 61850‑1 IEC 61850‑6; IEC 61850-7 ÷ IEC 61850-7-5); IEC 61850-8-1; IEC 61850-9-2; IEC 61850-10. Based on the analysis of these standards in the article presented, from the conceptual point of view, the perception in the understanding of the basic concepts of modeling and description methods for information models of stations and substations, the functions of devices used in the automation of substations and communication systems to provide interoperability within substations.

Practical Feasibility

Modern power-network communications are based on the IEC 61850 series standards. In this paper, we investigate the real-time performance and the vulnerabilities and attack scenarios at the sensor level communication networks more precisely on Sampled Measured Value protocol. The approach jointly evaluates the communication protocol, network topology and impact on electrical protection functions. We test the practical feasibility of the attacks on an experimental workbench using real devices in a hardware-in-the-loop setup. The tests are conducted on the two high-availability automation networks currently used in IEC 61850 process bus communications: Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR)
