HIL Microgrid Testbed
Solar and wind power generation, as well as battery storage, are all part of today’s microgrids. Together with protective relays, communication networks and microgrid controllers they are complex power systems that need thorough testing and verification before their safe and reliable operation can be guaranteed in all operating conditions. Distribution grids are undergoing rapid transformation that is fueled by introduction of intermittent and distributed power sources and by extensive application of information and communication technologies. Such transformation brings opportunities to make the distribution grid more resilient and more flexible. At the same time, it needs advanced testing tools to ensure the acceptable cost of quality.
What is a HIL Microgrid Testbed?
A Microgrid Testbed is a collection of HIL devices with integrated protection relays, microgrid controllers and controllers of solar inverters, battery inverters, diesel gensets, fuel cells, etc.
The main purpose of the Microgrid Testbed is to comprehensively test and validate primary and secondary control, communications and protection under all operating conditions including faults in both the islanded and grid-tied mode.
Moreover, Microgrid Testbed can perform all its tests and generate its test reports in the fully automatic mode, thus boosting the productivity and improving test coverage even further.
How does the C-HIL Microgrid Testbed work?
HIL Microgrid Testbed has an identical control system as a real microgrid, only the power hardware is digitized within the HIL devices.
High fidelity models of DER and distribution system hardware, comprising smart inverter hardware, PV panels, batteries, transformers, generators, switches, cables, active and passive loads etc. are simulated on ultra-low latency Microgrid testbed with time steps as low as 500ns.
Smart inverter controllers control the operation of smart inverter models, while relays control the protective switches and microgrid controllers provide the overall supervisory control.
A New Benchmark In Protection Testing
With Typhoon HIL API and Python scripts, you can fully automate testing against short circuits, phase losses, overvoltage’s, low and over voltage ride troughs and component failures.
Furthermore, HIL Microgrid Testbed allows you to conduct a sensitivity analysis of the whole network in real-time. With protection relays and all control components being real, and with the unparalleled accuracy of Typhoon HIL’s industry-proven advanced numerical modelling algorithms, you can validate microgrid models in the early stage of development.
