TL;DR: It is recommended that proof-of-concept interoperability should be preformed before full scope integration, and it is crucial to adopt interoperability testing as part of site commissioning test.
Abstract: This paper discusses the factors affecting interoperability between multi-vendor devices, the necessity for interoperability testing, and the types of interoperability should be conducted. It is recommended that proof-of-concept interoperability should be preformed before full scope integration, and it is crucial to adopt interoperability testing as part of site commissioning test. Interoperability testing is the next step forward after conformance test to ensure an IEC 61850 based substation automation system will interoperate as it is designed in the field. Conformance test can reduce the number of costly issues and problems during integration, site commissioning and operation. Devices passed conformance test may still subject to issues during integration, commissioning and operation. Conformance test does not mean interoperability test. Conformance testing cannot replace interoperability testing.

TL;DR: The suitability of various Ethernet LAN architectures for substation automation system applications with protection, control, monitoring data flows and their performance requirement and the redundancy technologies for mission-critical, time stringent realtime tasks such as SMV and GOOSE tripping over the Ethernet LAN applications are examined.
Abstract: This paper investigates various Ethernet LAN architectures for substation automation system applications with protection, control, monitoring data flows and their performance requirement. The paper discusses conceptual architecture designs and related redundancy technologies such as RSTP, PRP and HSR protocols. The suitability of these architectures and the redundancy technologies for mission-critical, time stringent realtime tasks such as SMV and GOOSE tripping over the Ethernet LAN applications are examined.

Abstract: Due to the recent changes in electrical networks, microgrid operation schemes have evolved dramatically. Coupled with smartgrid concepts, microgrids are required to be more intelligent and establish communication with its components. In order to sustain reliable and sustainable power delivery under heavy deployments of Distributed Generators (DGs), passive power network operation schemes have to be replaced with new generation dynamic methods. Utilization of communication in microgrids brings about new challenges such as communication reliability, time delays, plug-and-play and standardization considerations. Having a standard communication procedure has utmost importance in a network where there are different equipments manufactured by different vendors and having different features. IEC61850 substation communication standard has been introduced by International Electrotechnical Commission (IEC) to address this challenge. It has received much attention in power engineering circles and several pilot projects have been implemented. As a result, it has been found out that several concepts such as interoperability and interchangeability have to be considered in networks designed with IEC communication standards. This paper summarizes the latest developments in this field and discusses the required steps that shall be taken to unleash capabilities of microgrids in current smart network era.

TL;DR: In this article, the authors discuss the expectation on IEC 61850 interoperability and highlight the findings which were observed during the execution of the initiatives above, such as the development of an IEC61850 laboratory, new product acceptance process for IEC-618-50 devices and in-house software applications for I-6-50 substations, and conclude that the interoperability is one of the important aspects to ensure the success of a Smart Grid implementation.
Abstract: Interoperability is one of the important aspects to ensure the success of a Smart Grid implementation. Interoperability is defined as the ability of the devices and systems in a Smart Grid domain to be able to seamlessly communicate and exchange information with each other. As the public electric utility company in Malaysia, Tenaga Nasional Berhad (TNB) believes that the interoperability of solutions from different vendors in Smart Grid domain using open standard is the way forward and has the promising potential to provide substantial cost savings in the near future. TNB has identified the IEC 61850 standard as the key enabler standard for this purpose and has included the standard as a part of the long term technology implementation plan under the TNB Technology Road Map (TRM). To ensure the successful implementation of IEC 61850 standard in a Smart Grid domain, TNB has embarked in several initiatives, such as the development of an IEC 61850 laboratory, new product acceptance process for IEC 61850 devices and in-house software applications for IEC 61850 substations. This paper will discuss TNB's expectation on IEC 61850 interoperability and highlights the findings which were observed during the execution of the initiatives above.

TL;DR: This paper presents a technique to assess the performance of merging units from different manufacturers, when operating with intelligent electronic devices, performing a distance protection function.
Abstract: Substations are increasingly reliant on devices compatible with IEC61850 standards. However, the conformity of a device with the standards does not necessarily guarantee interoperability with devices from different manufacturers. The use of devices compatible with IEC61850 standards presents a challenge to many system integrators, especially due to a lack of familiarity with features, such as generic object-oriented substation event, reporting, sample values, and the need for system redundancy. To facilitate a smooth implementation, all of the features and the data exchanges between devices need to be tested to ensure the system operates correctly. It is important to determine the compatibility of the devices made by different manufacturers. This paper presents a technique to assess the performance of merging units from different manufacturers, when operating with intelligent electronic devices, performing a distance protection function. The performance of the process bus with a parallel redundancy protocol is evaluated using a closed-loop approach involving a real-time digital simulator.
