A team of researchers from Yeungnam University and KEPCO Research Institute have developed a simulation of the Korean power grid using ProTRAX software. As published in the Journal of Sustainable Development of Energy, Water and Environment Systems, the team developed a simulation “to investigate the performance and output characteristics of a megawatt-scale high-power BESS [Battery Energy Storage System] connected to the power grid for frequency regulation.”
TRAX worked with Professor Ki-Yeol Shin to provide dynamic modeling, engineering support, and software interface tools to allow design, testing, and tuning of the Siemens controls for a 4 MW Energy Storage System (ESS). The dynamic models included:
- Multiple generating units for a maximum 500 MW capability
- Multiple variable loads with a total power consumption of 500 MW
- Four 1-MW Power Conditioning System sets. This equipment provides up to 4 MW of power and contains:
- Two 1MWH lithium battery clusters
- One power conditioning module supporting bi-directional flow
- One 440V/22.9KV transformer
- Other electrical components (busses, breakers, etc.) forming a complete electrical network
After the initial work was complete, the modeling scope was expanded to encompass a total grid size of 7GW, including 345KV distribution, 27 major generating stations, and 28MW of energy storage.
“The power load model has similar characteristics to the real electric load of the power grid and could be very useful for validating an ESS controller for frequency regulation.”
TRAX is looking forward to Professor Shin’s next project!
