Several inverter control strategies have been proposed to facilitate the transition from synchronous machines to inverterbased generators within electric power networks. This transition necessitates the development of novel power system modeling and analysis techniques to solve the power flow problem. The control schemes of inverter-based resources operating in grid-forming and grid-following modes are considered. Grid-following inverters are modeled as negative loads and their control mechanism is not considered. However, consideration is given to grid-forming inverters control based on droop, virtual synchronous machine, and dispatchable virtual oscillator. A comprehensive power flow model that incorporates the terminal characteristics of these resources is developed. Then, Newton’s solution method for computing the unknowns in this power flow model is presented and the structure of the associated iterations is leveraged to formulate a quasi-Newton algorithm.
