There's more to power storage than a battery

摘要

At the time of its commissioning, the 32MW unit was the largest Lithium-Ion battery array in the world. But the battery is only half of the equation. Its controls are the other half. In that effort, Parker Hannifin provided assistance with inverters that transform dc power to ac, and the reverse when charging the battery. "The Parker part of the equation is the Power Conversion System (PCS), and it is a traffic cop between the grid and batteries," says Louis Lambruschi, Parker's marketing services and e-business manager. The PCS lets the batteries charge when there is an excess of grid power and discharge when the stored power is needed.
