Power from Shore (PfS) projects present different engineering obstacles from concept to commissioning to life cycle operation. As PfS functionality are primarily grid-related topics, the possibilities of site-specific testing are limited before all equipment are assembled on site and integrated in full-scale into the system. There are possibilities prior to perform "string tests"to bring together transformers, converters, filters and temporary use a of a load bank, where it has its advantages and disadvantages. This paper will focus on a recent case example of hardware-in-the-loop (HIL) Simulator and testing campaign for the electrification and expansion of a Norwegian offshore platform with two medium-voltage static frequency converter systems and two booster compressor variable speed drives as the core part of the HIL. © 2024 PCIC Europe Association.

With the penetration of a high proportion of renewable energy, grid-connected inverters are facing severe stability risks under weak grid. For the grid-following inverter, the phase-locked loop (PLL) is the dominant loop that triggers system instability. Therefore, in recent years, many improved PLL schemes have been proposed to enhance the system stability, but they neither have a significant impact on the system dynamics or lack the capability of precise impedance injection. Hence, this paper proposes a dual-PLL structure scheme, in which the current loop and grid voltage feedforward adopt different PLL. It realizes precise reshaping on the output impedance of the inverter, and enhances its low-voltage ride through (LVRT) capability while ensuring system dynamics. simulation and hardware in the loop (HIL) experimental results have verified the effectiveness of the proposed method. © 2024 IEEE.

The control of a modular multilevel converter can be achieved in various ways. Traditionally, upper-layer energy controllers and middle-layer current controllers are centrally implemented. In some hardware realizations, the submodules also include a local current measurement for purposes of protection and intra-branch energy balancing. In this case, the central controller may also use these measurements for the current control. However, the communication between submodules and the central controller delays will affect the current control's maximum achievable bandwidth. To mitigate this, a distributed implementation is investigated, where the current control is realized locally in the submodule. Analysis of the benefits and drawbacks of this implementation compared to a fully centralized controller are supported by hardware in the loop simulation of a medium voltage test setup. © 2024 IEEE.

Recent studies introduce new controllers that leverage the flexibility of inverter-interfaced generation for voltage control. However, only a few discuss the practical implementations of such controllers. Bridging this gap between theoretical designs and real-world deployment is crucial to validate the results obtained in numerical simulations. In this paper, we present a hardware-in-the-loop testbench for assessing the performance of various controllers in a high-fidelity simulation. In particular, we consider a feedback-based controller that pursues the optimal solution to an AC optimal power flow problem, while ensuring anytime satisfaction of the operational constraints, using voltage and power measurements. The controllers are tested on a 20-node distribution network with a realistic setting, considering modeling uncertainties and communication delays. We highlight the benefits of feedback-based controllers compared to omniscient controllers, and their robustness with respect to modeling uncertainties. © 2024 IEEE.

This paper presents a Finite Control Set Model Predictive Control (FCS-MPC) algorithm for the three-phase 5-level multiplexed converter (3φ5L MLMXC). The 3φ5L MLMXC comprises two Flying Capacitors (FC) topologies connected to the three-phase NPC topology. The main idea of the proposed control algorithm is to balance the flying capacitors placed in the top and bottom FC converter. The proposed topology is deeply described, and the MPC algorithm for 3φ5L MLMXC has been presented. The SVM algorithm has been implemented in a field-programmable gate array (FPGA). simulation and hardware-In-the-loop results show the usefulness of the presented analysis. © 2024 IEEE.

The surge in distributed generators from renewable sources has reshaped electric power systems, demanding advanced automation. Current engineering and validation methods focus on traditional offline and component validation, neglecting holistic system testing which can have impacts on the overall system resilience. Real-time simulators and hardware-in-the-loop tests address some gaps, but challenges persist in validating large-scale distributed software ecosystems in digitalized power systems. This paper tackles this by introducing the Automated Cyber-Physical Testing and Validation framework (ACTV). The goal of ACTV is to automate the process of system tests for large-scale smart grid applications. It does this by seamlessly integrating into a traditional software development process. Furthermore, it allows different organizations to collaborate in the validation process. Using the ACTV, it is possible to streamline the development and validation while ensuring modularity, reusability, and scalability. A prototypical implementation is presented and demonstrated in a smart charging use case. Summarizing, the ACTV framework provides a systematic approach for testing large-scale distributed software ecosystems before deployment, saving significant time and resources. © 2024 IEEE.

Power-hardware-in-the-loop Emulation of the Low-Frequency Oscillation Phenomenon in AC Railway Networks

Dynamic interactions among the AC railway traction network and power electronics converters feeding the trains have been reported to cause low-frequency oscillations (LFO) of the catenary voltage and current. This can result in railway system instability, eventually leading to a power outage and the shutdown of the train traffic. To avoid LFO, control of train power electronic converters must be properly designed and tuned. Experimental verification of control performance regarding the LFO phenomenon in the railway traction network is not easy. Alternatively, the railway traction network can be emulated using a power electronic converter, which would feed the train power converter under test. This paper addresses the design of a network emulator able to reproduce the dynamic behavior of the actual network at low frequencies, including LFO. Three different options will be considered for the network emulator. Their performance will be studied first by means of simulations. Finally, the selected solution will be verified on a downscale test bench.

The role of control techniques is increasing due to the high penetration of renewable energy sources at grid level. The importance of inverters also rises as it balances the supply between the renewable source and grid power system. The issues related to penetration of renewable energy like power quality maintenance, protection against the detection of islanding and maintaining the integrity of grid;control techniques play a vital role to solve these problems. This paper proposed an internal control technique known as current based sliding mode control (SMC) for a filter less multilevel inverter (MLI). The aim of proposed research work is to achieve 27 level output voltage by using an inverter, which approaches sinusoidal wave without using any filters. To control the output of MLI, a current based SMC is implemented in order to achieve the robustness, a good dynamic response, a smaller number of voltage ripples and a smaller current THD. Moreover, a comparative analysis of SMC is done with the conventional PI controller. The response of the controller has been investigated for different cases e.g., introducing sag, swell, faults and harmonics in grid level has been implemented on MATLAB/Simulink. To validate the results of SMC for MLI, an experimental setup was also established which consists of National Instruments (NI) based hardware in loop (HIL) system and dSPACE 1202. The HIL system results show consistency with simulation results.
