“…The validation was focused on the autonomous frequency droop control of the battery energy storage system (BESS) and the DG sets in islanded microgrid. The PV inverter that provides local control of frequency and voltage support functions was tested [19]. The low-voltage (LV) microgrid was modeled in the PHIL simulation, and the PV inverter under test was connected to a bus of the microgrid via a power amplifier and a current sensor.…”

Required functions of a microgrid become divers because there are many possible configurations that depend on the location. In order to effectively implement the microgrid system, which consists of a microgrid controller and components with distributed energy resources (DERs), thorough tests should be run to validate controller operation for possible operating conditions. Power-hardware-in-the-loop (PHIL) simulation is a validation method that allows different configurations and yields reliable results. However, PHIL configuration for testing the microgrid controller that can evaluate the communication between a microgrid controller and components as well as the power interaction among microgrid components has not been discussed. Additionally, the difference of the power rating of microgrid components between the deployment site and the test lab needs to be adjusted. In this paper, we configured the PHIL environment, which integrates various equipment in the laboratory with a digital real-time simulation (DRTS), to address these two issues of microgrid controller testing. The test in the configured PHIL environment validated two main functions of the microgrid controller, which supports the diesel generator set operations by controlling the DER, regarding single function and simultaneously activated multiple functions.

“…PHIL is described as a unique approach to testing, because different power systems can be scaled down. It can be tested under realistic conditions with a Hardware Under Test (HUT) device connected to a real-time simulator [8]. The scalability of equipment therefore reduces overall cost and space required for hardware equipment.…”

“…The Controller Hardware in the Loop (CHIL) simulation is another type of HIL simulation which is used for low-level digital or analogue testing [9]. Both CHIL and PHIL been discussed extensively and used in different power applications [8][9][10][11][12][13][14][15][16][26][27][28][29].…”

Power generation via Distributed Generation (DG) plants coupled with inverters can participate in Frequency and Voltage stabilization of the microgrid which is important to grid operators. This paper explores the realization of improved regulation of frequency and voltages in a low voltage microgrid using droopcontrolled power converters. The test bed consists of a Power Hardware in the Loop (PHIL) setup, which includes a gridforming battery inverter, local loads, and DG plants. In the PHIL setup, the grid-forming battery inverter was responsible for setting the network voltage, which served the loads initially before the distributed energy resources were energized. Additional loads were then switched on triggering a frequency drop in the network. Changes in the load requirement and performance of the DGs were examined through the PHIL setup with the energy storage system further supporting as require. The results showed notable improvement in the overall system frequency and voltage regulation.

“…Basic topologies of controller hardware in the loop (CHIL) and power hardware in the loop (PHIL) testing[101].Decades ago, analogue simulators or transient network analyzers (TNAs), composed of scaleddown physical models, were used for FACTS and HVDC controller testing, which were simplified and presented limited flexibility[102,103]. The emergence of digital real-time simulation allowed a realistic representation of the network and FACTS converter, allowing efficient testing of FACTS controllers and thus leading to fewer problems at the commissioning phase and field operation.…”

The role of flexible alternating current transmission systems (FACTSs) in the provision of grid services is becoming increasingly important, due to the massive integration of intermittent renewable energy sources, energy storage systems, and the decommissioning of thermal plants. A comprehensive literature review of grid services offered by FACTS is performed, focusing on the different grid services that they can provide, such as power flow control, reactive power control, voltage control, power quality improvement, harmonic mitigation, improvement of transient stability, and damping of inter-area and intra-area oscillations. These grid services need to be realistically and economically validated in suitable testing environments. A review of relevant standards, guides, and the literature is performed, which covers the entire range from functional specification and factory testing up to the field testing of FACTS. Advanced industry practices, such as controller hardware in the loop (CHIL) testing of FACTS controllers by the manufacturer, and recent trends, such as CHIL testing of replica controllers by the owner, are underlined. Limitations of conventional testing and CHIL testing are explained and the use of power hardware in the loop (PHIL) simulation for FACTS testing is discussed. CHIL and scaled-down PHIL tests on a transmission static synchronous compensator (STATCOM) are performed and a comparison of the results is presented.
