PHIL test bench/Electric power

CPV codes

Description

Faculty of Science and Technology, Department of Electrical Engineering and Computer Science, would like to procure an integrated test bench that enables research in several active and emerging areas - areas that attract considerable national and international competitive financing: • Renewable Energy Integration — Testing photovoltaic inverters, wind converter controls, and grid-forming strategies under realistic and adverse grid conditions without access to a live grid. • Microgrid Design & Validation — Emulating DERs and microgrid topologies in real time to evaluate control, protection, and islanding behavior for both AC and DC microgrids. • Grid-Connected EVs & V2G — Studying vehicle-to-grid (V2G) bidirectional charging and its impact on grid stability; a field identified as strategically important for the energy transition. • Power Converter Development — Validating novel converter topologies and modulation strategies at power levels that expose real thermal and dynamic behavior before committing to expensive physical prototypes. • Cybersecurity of Energy Systems — Remote controllability and isolation of the bench allows simulation of cyber-physical attack scenarios on smart inverter systems in a safe environment. • Synthetic Inertia and Grid-Forming Controls — Testing virtual synchronous machine algorithms and synthetic inertia controllers against real grid angle swings, which is impossible with pure simulation. "Power Hardware-in-the-Loop" technology (PHIL) is becoming the standard method for validation of power electronics, converters, micronet management systems and distributed energy resources (DEREs). The procurement of such a test bench will give the laboratory a boost in this field, facilitate a new generation of externally financed research programmes, and give students practical experience with the same tools used in the industry and at national laboratories around the world. Reasons for a direct procurement due to technical reasons: The instrument must meet the following criteria in order to fulfil our needs: • A solution with native or first-class integration with MATLAB/Simulink as our students at UiS use this software predominantly. • Desired model import possibility from PowerFactory. As this is the specific power systems simulation software power engineering students at UiS are using and that they most likely use it in thesis projects. • Microgrid and component models are already available in the simulator for quick start. Integrated control system for amplifiers. • Compatibility with 400V RMS line-to-line voltage. • Possibility to integrate multiple Distributed Energy Resources, DERs (Device Under Tests, DUTs) with real-time-simulation. • Most importantly tested and integrated solution consisting of real-time simulator, output interfaces, bus bars, power amplifiers DC power supplies, safety equipment and Power Distribution Units, PDUs. The integrated solution shall consist of: * 4Q Power Amplifiers * Two to three Bidirectional DC power supplies allowing the amplifiers to consume or to feedback power from/to the 3-phase mains input. "The Microgrid PHIL test bench" from OPAL-RT is a purpose-built, pre-integrated platform that enables real hardware to be tested within a fully simulated power grid environment in real time. The simulation and power amplifiers are completely integrated and compatible with each other in terms of communication and software needs. OPAL-RT is the only supplier providing such integrated solutions. Although there is possibility to buy equipment from other technology providers, it will require integrating a separate vendor’s hardware. This will – if, at all, possible – require an unknown amount of engineering hours (of which we are short of) and time. OPAL-RT's edge is integration and turnkey simplicity in the 5–30 kW range. The fact that related systems are being used in multiple universities in Norway (such as NTNU and UiA) will create opportunities to collaborate on joint projects. To summarize, the PHIL Prime test bench is the only fully integrated bench of its kind in the market. We would therefore like to go to direct procurement of POWER-HARDWARE-IN-THE-LOOP TEST BENCH FOR MICROGRIDS in accordance with the Public Procurement Regulations, cf § 13-4, point b part 2 "competition is impossible for technical reasons".
