Abstract
The integration of smart grid technologies in interconnected power system networks presents multiple challenges for the power industry and the scientific community. To address these challenges, researchers are creating new methods for the validation of: control, interoperability, reliability of Internet of Things systems, distributed energy resources, modern power equipment for applications covering power system stability, operation, control, and cybersecurity. Novel methods for laboratory testing of electrical power systems incorporate novel simulation techniques spanning real-time simulation, Power Hardware-in-the-Loop, Controller Hardware-in-the-Loop, Power System-in-the-Loop, and co-simulation technologies. These methods directly support the acceleration of electrical systems and power electronics component research by validating technological solutions in high-fidelity environments. In this paper, members of the Survey of Smart Grid International Research Facility Network task on Advanced Laboratory Testing Methods present a review of methods, test procedures, studies, and experiences employing advanced laboratory techniques for validation of range of research and development prototypes and novel power system solutions.

Summary
Increasing deployments of distributed energy resources (DER) and smart grid technologies in cyber–physical energy systems, has driven the scientific community and power industries to develop novel technologies. In order to ensure a smooth transition to a more distributed grid with higher penetration of renewable energy units, new procedures and methods for testing and validating interoperability, reliability, and stability must be developed To address this need, researchers have developed advanced laboratory evaluation methods based on real-time simulation (RTS) and Hardware-in-the-Loop (HIL) including: Power Hardware-in-the-Loop (PHIL), Controller Hardware-in-the-Loop (CHIL), Power System-in-the-Loop (PSIL), and co-simulation that improve the fidelity of smart grid simulation tools. The classification of geographically distributed (GD) simulation setups is currently being undertaken within the IEEE PES Task Force on Interfacing Techniques for Simulation Tools, with the broadly identified classification reported here as: Geographically distributed RTS: in this group only RTSMs at both ends are coupled together This is used to overcome large simulation complexity that would require large RT resources that might not be available in a single test site. The research community keeps putting efforts on development of platforms for validation according to grid codes and pre-certification of units [47,82,83,84], definition of procedures for compliance testing and acceptance tests [85,86,87,88,89], and validation of marine- and aero-electrical power systems [90,91,92,93].
