2. Parallel Operation of Grid-Forming Power Inverters
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. READ MORE
