In this paper a power hardware in the loop simulation has been realized to test in a safely way the performances and reliability of a device called "powerCorner" used to supply an islanded microgrid. A real-time model has been developed in order to simulate the microgrid, batteries and photovoltaic panels. Some modeling criterions have been proposed to reduce time-step simulation and enhancing the power hardware in the loop simulation stability. power hardware in the loop simulation is used to emulate the AC and DC environments around the power inverters. On the DC side, DC power amplifier is used to emulate photovoltaic power plants and storage devices made on Lithium batteries. On the AC side, AC power amplifier is used to emulate the behavior of the microgrid. These two power amplifiers are controlled by a digital real time simulator which embeds the dynamic behavior of both DC and AC sides.

power hardware-in-the-loop (PHIL) enables realistic hardware testing interfacing with a simulated environment. The PHIL nature calls for power interfaces, such as analog-todigital converters, the power amplifier, and sensors, containing latency and noise. These elements are non-ideal, leading to inaccuracies and even instability. Accordingly, accurate modeling of a PHIL setup has become a challenging research topic. This paper presents accurate modeling of a PHIL setup approaching the actual hybrid analog/digital PHIL characteristics to ensure high accuracy in a wide frequency spectrum range. The proposed technique applies multirate discrete modeling, considering digital/analog sections as if in an actual setup. The accuracy is defined and evaluated over the frequency range of interests. The prominent voltage-type ideal transformer method (V-ITM) is employed as the interface algorithm. The proposed multirate discrete modeling is compared with purely continuous and singular discrete modeling approaches, considering all interface delays and dynamics while operating different hardware, namely, RL and RLC load. Frequency responses reveal a significant accuracy improvement in the proposed method. The step response similarly confirms the better performance of the proposed model in replicating the transients. The modeling methods are simulated using Simulink/MATLAB to confirm the validity of the proposed model.

The energy systems are evolving towards the wide integration of power electronics-based technologies, such as electric vehicles. A promising solution to increase the grid controllability is represented by grid-forming converters, such as smart transformers (STs). Being a new technology, the ST experimental testing is a fundamental step before commercialization. Instead of performing time consuming and not flexible on-field tests, the power hardware In the loop (P-HIL) offers a flexible testing environment for experimentally validating new technologies. The real-time simulation of the electrical grid offers the possibility to vary quickly the testing environment, while the power amplification stage offers the validation of the real hardware. Despite the clear testing advantages, the P-HIL stability and testing accuracy is still a matter of study. This paper introduces a new P-HIL interface approach for ST application, that can guarantee high testing accuracy in a large frequency spectrum. The proposed approach combines the tracking capability of the existing controlled Current-Type P-HIL interface algorithm, with the well-known Partial Circuit Duplication approach. The accuracy and stability analysis has been performed analytically and validated by means of extensive experimental P-HIL testing.

Modern power systems are becoming more and more complex, in order to handle the growing spread of Renewables and of Electric Vehicle charging stations. The control capability relies on the integration of Information and Communication Technology (ICT), including accurate time distribution mechanisms, such as the IEEE 1588 protocol, to the existing distribution grid infrastructure. The validation of such complex systems can hardly be performed in real environments, for both technical and economic reasons. power hardware in the loop (PHIL) emulation systems have already been demonstrated to be effective for this scope. The design of a testbed for the validation of IEEE 1588 power profile based on PHIL solutions requires the capability to synchronize the time bases of the elements forming the testbed. Commercial PHIL systems often offer proprietary synchronization solutions, but these approaches cannot be applied in the general case. In this paper, a software-based solution, able to time synchronize PHIL with IEEE 1588 devices, has been investigated. Such a solution has the advantage that it does not require dedicated hardware, thus it can be applied to different PHIL systems. The experimental characterization highlights that, using such approach, it is possible to reach a time synchronization with an expanded uncertainty (k=3) of 0.75 mu s, more than enough to correctly emulate events on the power grid.

The objective of this work is to analyze the dynamic behavior of a generator which uses a grid-connected inverter with an output LC filter. In this paper, we focus on modeling and simulating this kind of inverter using real time simulation. A control strategy based on resonant controller is proposed. State feedback structure and pole assignment methods are used to design the controller. To test this control algorithm, a virtual PWM converter is embedded in a real time simulator. Using interpolation techniques, the controller can directly control this virtual inverter with real PWM high frequency signals.

IEEE International Autumn Meeting on power, Electronics and Computing (ROPEC)

The aim of this study is to present an improvement of the Damping Impedance Method (DIM) Interface Algorithm for power hardware in the loop (PHIL) simulations. The improvement is based on the calculation of the hardware Under Test (HUT) impedance, in order to include it as part of the Damping Impedance Method to enhance its accuracy and stability. To verify the results, the improved DIM interface is simulated using MATLAB/Simulink, furthermore, a laboratory implementation of a PHIL simulation is carried out using a variable load. The stability of the interface algorithm is graphically observed using the Nyquist and Bode stability criteria, whereas the precision is validated through simulations that compare the Mean Square Error (MSE), as well as laboratory experiments.
