The share of the renewable energy sources (RESs) in electrical power system is continuously increasing. As a result, the conventional power plants, which mostly utilize large synchronous generators (SGs), are taken out from the operation and this leads to power system stability concerns. The conventional grid-following control strategies for RESs do not contribute to the stability. On the other hand, grid-forming (GF) controls acts as a voltage source in a system, and can perform an operation similar to SGs. In this study an RMS model of GF converter is built. The GF converter model is implemented to a simple power system and fed by a renewable energy source. The results showed that a GF converter can operate like a SG and it can perform load sharing based on its implemented droop curve. In addition, two adaptive droop control methods are introduced for frequency control in the power system. A battery storage system is proposed to support DC voltage during immediate power demands. The study is performed in DIgSILENT PowerFactory.
