Wide area synchronous grids
“How do electrical grids operate at large scale?”
Electrical grids are one of the life beds of modern infrastructure. However, since the power demands of humanity are too large for a single system to handle, the grid must be grouped into different synchronous “zones” to ensure smooth operation. Because of this, engineers have designed a framework that uses multiple distinct areas called wide area synchronous grids (WASGs) to operate at a synchronized frequency. WASGs in North America typically operate at 60Hz, while ones in Europe work at 50Hz. Interconnections between grids can be made by using HVDC lines. WASGs allow for energy generation pooling, which allows for lower generation costs.
