“…Some previous studies addressed the construction of an experimental framework to approximate the IEC61850 standard [14] [15] [16], considering physical constraints while maintaining scalability, to ease the way for more complex power grid implementations. The authors in [15], investigated complex protection coordination using the Arcteq-F215 IED. Their work redefines the relationship between primary and backup protection for microgrid protection.…”

Due to the increasing use of smart components in smart grids, interoperability among them is a crucial aspect to address. IEC61850 is a communication standard that has been already used in substations because of its instant data transfer and the ability to enable data exchange between a variety of smart energyrelated digital technologies. This article studies the application of the communication protocols defined by the IEC61850 standard in Intelligent Electronic Devices (IEDs) by using a prototype testbed architecture running on a real-time digital device. The goal of this activity is to study the impact of smart simulations and the vulnerability in terms of cyber-security. This testbed includes the supervisor, the substation bus, and the process bus communication layer creating a local network exchanging data at distinct levels. Different fault protection scenarios are discussed using both physical and emulated IEDs, and the communication protocols implemented in each scenario are explained showing that additional delays are introduced. In the first two scenarios, the operation of the testbed using physical versus emulated IEDs is analyzed and compared, ensuring the robustness of this methodology in situations where the use of a physical IED would be unfeasible. In these scenarios, the functionality and robustness of the protection mechanisms and communication protocols are confirmed. In the third scenario vulnerability of smart grids that use IEC61850 as their primary communication protocol to data injection attacks is studied. Sniffing the local network, packets are captured and monitored. Spoofed data with the same structure are injected into the network to conduct false data injection attacks on the supervisory unit. Vulnerability to cyber attacks of the IEC61850 protocol in specific situations is shown.

“…The master‐slave controlled microgrid can operate independently from the utility grid, a U/f‐controlled IIDG (U/f‐IIDG) is used as the main source to maintain the voltage and frequency stability of buses, and PQ‐controlled IIDGs (PQ‐IIDGs) are used as slave sources to provide the power to a microgrid 4,5 . The plug‐and‐play characteristics of IIDGs change the topology of microgrid, with the result that the traditional fault analysis methods are no longer suitable for microgrids 6,7 . How to establish the fault models of master‐slave controlled microgrids and calculate the fault characteristics quantitatively are the issues to be solved for the microgrid protection.…”

Summary The fault calculation of microgrid is an important method for fault characteristic analysis. The traditional fault analysis methods ignore the connection of inverter interfaced distributed generation (IIDG) and are not suitable for microgrids. A new fault analysis method suitable for the master‐slave controlled microgrid is proposed in this article, which considers the control strategy of IIDGs, low voltage ride through (LVRT) and the fault current limiting. The fault models of PQ‐controlled IIDG (PQ‐IIDG) and U/f‐controlled IIDG (U/f‐IIDG) are analyzed, then an equivalent Norton model of microgrid is established, and a new fault calculation method is presented. By analyzing the fault models, the working state of U/f‐IIDG is divided into a constant voltage state and a constant current state. In the constant voltage state, a grid‐connected microgrid fault calculation method is adopted. In the constant current state, the improved nodal voltage equation based on the current limiting is adopted. Without complicated calculation, high precision results can be obtained after simple iterative calculation. The results of the microgrid simulation model established in PSCAD/EMTDC and the fault calculation method programmed on MATLAB are compared to verify the effectiveness and accuracy of the proposed fault analysis method.

“…e last one considers a redial network to coordinate the OC relays based on the Genetic and Particle Swarm Optimization. In [13], the researchers propose a method for the protection of the microgrid rely in the IEC 61850 GOOSE messages to overcome the coordination difficulties due to multiple power sources, and the proposed method has been verified by a testing system. Another study [14] suggested an adaptive method by changing the setting groups of the relays via binary input depending on DGs connection state, for only DGs close relays based on the proposed sensitivity matrix.…”

Protection relays design and manufacture have arrived to a new level of advancement; hence, numerical relays have appeared recently. They combine all the functions of monitoring, control, and protection in one device. Also these relays have the ability to communicate with each other to share statuses and orders using GOOSE (generic object‐oriented substation events) messages based on communication protocols such as IEC61850. In this paper, a proposed method for overcurrent (OC) relay coordination has been introduced based on numerical relay features of several setting groups and communication capability. This work supposes that the coordination between feeder, bus section, and incomer protection relays, in a substation of single busbar configuration with bus sectionalizer (i.e., bus section), depends on the status of the bus section circuit breaker (CB) as a criterion for determining active relay setting group, to achieve a faster tripping action. ETAP has been used as a simulation software environment. And the simulation results show the advantages of the proposed method in reducing the time needed by the relay to clear the electrical fault. Siemens SIPROTEC series have been used as an example of numerical relays, specifically 7SJ64 as OC relay, which exists in the ETAP library.
