ePHASORSIM

Large-Scale Electromechanical Power System Real-Time Simulation

Power grids are increasingly stretched beyond their limits by renewable energy sources, overcrowding of networks facing exponential growth, as well as highly-enmeshed networks and new HVDC interconnections. This dramatically increases the operational complexity and control/protection demands of these grids.

ePHASORSIM excels at simulating extraordinarily large mixed T&D networks in real time thanks to its powerful phasor domain solver, helping engineers to study transient stability phenomenon and test the integration of EMS/SCADA systems. It outperforms as well at wide area protection and control schemes (WAMPAC)–or to train system operators with Hardware-in-the-Loop (HIL) simulations true to the real grid.

Real-Time Simulation of 100,000+ Nodes of T&D Systems

Here forty instances of the IEEE European Low Voltage Test Feeder are stitched to the IEEE 118-bus transmission system to synthesize a new test case that has over 108,000 nodes. The real-time simulation of such a massive T&D power grid uses parallel computation on only nine processing cores!

ePHASORSIM Helps Power Labs and Research Facilities to Focus On:

    • Real-time transient stability simulations for systems in range of 100,000+ nodes

    • Wide-area control/protection/state estimation algorithms

    • EMS tools and algorithms, such as AGC and load shedding

    • PMU streams and PDC applications

    • System studies with massive numbers of renewable penetration

    • Design and test local controllers, such as voltage regulators

    • Advanced metering and information network

    • Impact of load profiles in distribution networks
