A Power-HIL microgrid testbed: Smart energy integration lab (SEIL)

Abstract

Grid integration of distributed energy resources (DERs) is gaining importance in the field of power electronics research. Experimental evaluation of control strategies and detailed evaluation of power interfaces usually require significant allocation of time and resources. This is where the power-hardware-in-the-loop (PHIL) techniques help accelerate control design and evaluation processes. The paper presents a PHIL based microgrid testbed: Smart Energy Integration Lab (SEIL); that has been specifically constructed for studying grid integration aspects of DERs with a focus on system dynamic performance and power dispatch scenarios. The SEIL is equipped with a remotely controlled network configuration, power electronics converters, passive loadbanks, a battery storage system and real time control and acquisition systems that allow emulation of several microgrids and connection of several DERs at the same time. To demonstrate the functionality of the SEIL, the experimental results for two typical scenarios were used: a power dispatch scenario in a microgrid and a wind turbine operation in grid connection.

PRIME: a real‐time cyber‐physical systems testbed: from wide‐area monitoring, protection, and control prototyping to operator training and beyond

“…In the power systems domain, they are being introduced in all power system research areas. The list includes network communications [10], cybersecurity [11–16], distribution grid management [17], electric transportation [18], energy storage [19], demand response [20], and distributed energy resources [21, 22]. They are also applied to testing current and emerging WAMPAC applications [23–30].…”

Power and Communications Hardware-In-the-Loop CPS Architecture and Platform for DER Monitoring and Control Applications

“…Specifically, the increasing prevalence of DERbased CPS and their common-mode vulnerabilities may lead to cyber-threats and risk of tripping DERs offline, resulting in power disruptions and instability in the distribution grid operation. The HIL DER testbeds, such as power HIL [6], [7], communications HIL [8], power and controller HIL [9], have been developed with separate and dedicated HIL cosimulation approaches. Several existing DER CPS testbeds have been reviewed in [10].…”

“…Even though the microgrid concept has been extensively investigated in the literature [2], [3], [4], the research topics are mainly focused on pure electrical system. There are also laboratories and demonstration sites around the world [3], [5], [6], however, to the authors best knowledge, there are no laboratories in the world specifically focused on investigating the different energy systems with their interdependencies in a holistic manner.…”
