Research Roadmap on Grid-Forming Inverters

Simulating the Role of Grid-Forming Inverters in the Future

A Pacific Northwest National Laboratory (PNNL) research team recently developed a new model of an important device that acts as a kind of translator, allowing renewable power sources like wind and solar to better add their power to the electrical grid. The device, called a grid-forming inverter, plays a critical role in converting direct current (DC)

Resiliency improvement through grid forming inverter

Natural disasters may result in grid outages, which can impact critical loads. Thus, a resilience enhancement-oriented critical load restoration strategy is required. As transmission lines are exposed to these events, critical loads cannot rely on the grid. The microgrid must be able to deliver power to these critical loads during such events. In this
