“…Traditionally, AC ship systems were arranged radially, an orientation that has the benefit of simplicity; however, these structures lack survivability, as if a line is disconnected due to a fault, there are no other connections to the load to power it [9]. Several papers have highlighted the benefit of utilising an open ring bus structure [34,39]. This structure is capable of isolating a fault with a normally open point, therefore allowing the rest of the system to continue to operate.…”

This paper presents a complete review of MVDC applications and their required technologies. Four main MVDC applications were investigated: rail, shipboard systems, distribution grids, and offshore collection systems. For each application, the voltage and power levels, grid structures, converter topologies, and protection and control structure were reviewed. Case studies of the varying applications as well as the literature were analyzed to ascertain the common trends and to review suggested future topologies. For rail, ship, and distribution systems, the technology and ability to implement MVDC grids is available, and there are already a number of case studies. Offshore wind collection systems, however, are yet able to be implemented. Across the four applications, the MVDC voltages ranged from 5–50 kV DC and tens of MW, with some papers suggesting an upper limit of 100 kV DC and hundreds of MV for distribution networks and offshore wind farm applications. This enables the use of varying technologies at both the lower and high voltage ranges, giving flexibility in the choice of topology that is required required.

“…Experiments have been performed in which the motor-generator is physically present and also in the scenario where the same motor-generator source is emulated using a hardware in the loop platform (HIL). While there is existing work discussing the emulation of power hardware with HIL systems [6][7][8][9]. The goal of this work is to demonstrate the validity of studying a general power system using sources that are emulated using HIL by comparison to real hardware testbeds.…”

“…Power Hardware in the Loop (PHIL) offers potential benefits to the design and development process of power systems [6][7][8]. PHIL allows for the real-time emulation of a physical component or control system that is not in possession [9]. As seen in Figure 3, a model of the desired component is deployed on a real-time computer system.…”

Future electrical power systems will integrate a significant number of distributed generation sources that are all intelligently monitored and controlled. It is not always possible to have each potential type of generation source present for laboratory evaluation, and thus hardware-in-the-loop has emerged to utilize hardware validated models as hardware emulated sources in laboratory testbeds. At the University of Texas at Arlington, a low power testbed has been setup on which real and emulated generation sources can be seamlessly integrated and studied under load profiles representative of an end user's application. In the work presented here, a hybrid power system that integrates batteries, ultracapacitors, and an AC generator is being studied. The AC generator is implemented using hardware and then emulated using an OPAL-RT hardware-in-the-loop platform. The validity of using hardware-in-the-loop to emulate these types of sources as well as the ability of the hardware energy storage to buffer the generator is being studied. A description of the hardware setup will be presented along with results collected to date.

“…Several researchers have developed small prototypes to verify their control algorithms. The algorithms are developed early in the simulation process and need to be written for the controller chosen to run the prototype, which takes time and effort and is costly [10][11][12][13][14][15][16][17][18][19][20][21]. As an emerging technology, there are few tools for MMC controller design and no established standards to guide engineering practices for MMC control and operation.…”

Modular multilevel converters (MMCs), with their inherent features and advantages over other conventional converters, have gained popularity and remain an ongoing topic of research. Many scholars have solved issues related to the operation, control, protection, and reliability of MMCs using simulation software and small hardware prototypes. We propose a novel approach for an MMC controller design with real-time systems. By utilizing a key benefit of LabVIEW Multisim co-simulation, an MMC control algorithm that can be deployed on a field-programmable gate array (FPGA) was developed in LabVIEW. The complete circuit was designed in Multisim, and a co-simulation was performed to drive an MMC model. The benefit of this topology is that control algorithms can be designed in a LabVIEW FPGA and tested with the Multisim co-simulation circuit to obtain simulation results. Once the controller works and provides satisfactory results, the same algorithm can be deployed in any NI (National Instruments) FPGA-based controller, like a compact remote input/output (RIO), to control real-time MMCs designed in an NI PCI eXtensions for Instrumentation (PXI) system. This method saves time and provides flexibility for effectively designing control algorithms and implementing them in an FPGA for real-time model implementation.
