Ultimate test solution for microgrid control system verification
What is a microgrid?
Microgrid is a collection of distributed energy resources (DER) that insure high power quality and can also be seamlessly connected to a wider distribution system.
What is Microgrid Testbed?
Microgrid Testbed is a collection of HIL devices from Typhoon HIL with integrated DER controllers, protection relays and microgrid controllers.
What is the purpose of Microgrid Testbed?
The main purpose of the Microgrid Testbed is to comprehensively test controller’s hardware, firmware, software and communications under all operating conditions including faults in both the island and grid-connected mode.
To help our customers reach a high level of test productivity, the Microgrid Testbed performs all its tests and generates test reports automatically.
How does Microgrid Testbed work?
DER and distribution system hardware models comprising smart inverter hardware, PV panels, batteries, transformers, generators, switches, cables, active and passive loads etc. are running inside a HIL device with a 1 μs time step. Smart inverter controllers control the operation of smart inverter models. Relays control the protective switches and microgrid controllers provide the overall supervisory control.
In other words the Microgrid Testbed has identical control system as a real microgrid, only the power hardware is digitized.
Test the microgrid components first. Then test the whole microgrid.
Distributed HIL for distributed energy resources testing
The future grid comprising a distributed and decentralized collection of microgrids requires a fast, powerful, high-performance decentralized HIL system where one HIL device models one microgrid island while the Microgrid Testbed models a collection of islands, i.e. the distribution grid.
This is precisely the scalability inherent in desktop HIL devices from Typhoon HIL.
Smart inverter control testing
Undoubtedly, the smart inverter is one of the key enabling technologies for microgrid development. The smart inverter is the interface between the DER and the microgrid distribution system and to a large extent comprises the intelligence behind the DER. Additionally, smart inverters are in charge of active and reactive power regulation, voltage and frequency regulation as well as mitigation of the harmonics in the grid.
Effective testing of the smart inverter controller is the foundation for the effective testing of the microgrid and that is where Typhoon HIL truly shines.
Test the relay protection and SCADA
Add the relays into your Microgrid Testbed and then put your microgrid/distribution grid through its paces: short circuits, phase losses, overvoltages, low voltage ride throughs and component failures.
Finally, top it all with the whole network sensitivity analysis.
With all other control components being real, it is only natural to use a real SCADA with all its functions and communication infrastructure.
Test your smart inverter controller with a 20 ns time resolution.
A 20 ns PWM resolution combined with 0.5 μs simulation time step enables the most realistic, and most comprehensive smart inverter controller tests. From DC to 200 kHz switching frequency, the extreme time resolution of Typhoon HIL devices simply shines.
Automate testing with Python: the ultimate ease of use.
Automate controller testing processes with Python scripting. Discover the most comprehensive power electronics control software testing environment where fault injection, such as grid disturbances, short and open circuits, are just one Python command away.
Use Python scripting and rich mathematical function library to quantify system performance in a broad spectrum of operating conditions, under standard operating conditions as well as under fault conditions (internal and external).

First of a kind Microgrid Testbed optimized for grid-code pre-certification.
The new Precertification Toolbox from Typhoon HIL, verified by the AIT Austrian Institute of Technology, allows you to exhaustively test your inverter control software in- house against national and international grid codes. Moreover, you will do it at a fraction of the time and cost. Even the highly demanding Low Voltage Ride Through and Frequency Droop test procedures can be completed with just few clicks thanks to the Typhoon HIL built-in test libraries.
Our Microgrid Testbed enables repeatable, formalized control system testing for a wide selection of operating conditions that are often impossible or impractical to test with real hardware. Digitizing the power components inside our HIL opens a world of possibilities to verify smart inverter grid compliance in-house by driving it through a wide range of standarddefined operating points. All with a simple push of a button.
Typhoon HIL Microgrid Testbed will automatically generate highly-detailed reports for all test operations with all test-relevant data captured in high-resolution.
