What is Grid-following and grid-forming PV and wind turbines about?

The share of renewable energy in global power capacity has grown rapidly in the last decade. As a consequence, more stringent grid interconnection requirements have been imposed by grid operators aiming to increase grid flexibility and maintain grid stability. Both photovoltaic (PV) power and wind power (WP) plants are connected to the grid through power converters which, besides transferring the generated DC power to the AC grid, should now be able to provide some services to the grid, such as dynamic control of active and reactive power, frequency and voltage ride-through, reactive current injection during faults, and participation in a grid voltage and frequency control, etc. In this chapter, we introduce the typical structures of PV and WP systems with a particular focus on the power electronic parts, especially gridconnected power converters. These power converters can operate either in the grid-following or grid-forming mode. The former has been widely used in PV and WP plants with maximum power injection as a primary objective, whereas the latter has emerged in the last few years due to growing concerns regarding the displacement of synchronous generation units by converter-
