MICROGRID DIRECT TRANSFER TRIP DESIGN AND SIMULATION
Powertech Labs is offering a new service to design, simulate, and test direct transfer trip for microgrid implementation.
Protection Co-ordination of Microgrids
The rapid development of distributed energy resources (DER)—such as solar photovoltaics, wind energy, battery storage, and hydrogen and electric vehicles—is revolutionizing the energy industry. For utilities, one common challenge in the proliferation of DER is to ensure the proper management of the microgrid in protection co-ordination with the utility grid.
For example, microgrids are usually located in remote or rural areas and connected to the utility’s long radial distribution feeders. In these configurations, when a fault is detected by the utility recloser, the recloser should send a protection trip signal to the microgrid controller to disconnect the microgrid from the system. This direct transfer trip (DTT) prevents the microgrid from islanding with the utility’s downstream feeders.
Powertech Labs provides the facilities and staff expertise for clients to design and simulate a DTT system. Services include:
Study, design, and sizing for microgrid implementation
Direct transfer trip and protection validation
Simulation of microgrid, DER, and protection schemes using Real Time Digital Simulation (RTDS) to confirm the DTT control scheme for both the microgrid and grid-tie (where applicable).
Our teams have decades of experience designing and testing utility industry equipment and DER technologies. Onsite outdoor and indoor labs include:
Realistic, utility-scale, and utility-integrated operating environment
Broad portfolio of DER co-located (for convenience) and inter-operable
Live 25 kV poleyard with open-loop distribution system, including distribution automation devices, SCADA, and communications systems
Hardware-in-the-loop (HIL) testing using RTDS system
Real-time automation controller (RTAC)
Simulation and testing of DTT systems enable utilities to safely and efficiently proceed with microgrid implementation. Benefits include:
DER selection, sizing, and curtailment design
Islanding protection and management
