TL;DR: In this article, a static synchronous generator (SSG) model was developed for grid-tied PWM inverters, which is similar in physical mechanism and equivalent in mathematical model.

TL;DR: This paper presents a comprehensive review of existing modeling and stability analysis methods for VSC dominated power systems, including their basic principles, key features, application scenarios and development tendencies.

TL;DR: In this paper, a real-time detection algorithm of decaying dc component is first developed for a generic single-phase distorted ac signal, and fast and robust elimination of both decaying dc transient and harmonics can be performed simultaneously in three-phase grids, by adoption of moving average filters in $d$ − $q$ frame and subsequent calculations.

TL;DR: It is proven that the RPC strategy can achieve consistent FR performance with respect to the optimal PD control, i.e., it can maximize the suppression of frequency deviation and RoCoF simultaneously, yet avoiding the limitations due to unknown grid parameters.

TL;DR: In this paper, a novel orthogonal signal-generation algorithm, which is characterized by remarkable response speed, high accuracy, noise immunity, and easy implementation, is developed in order to remedy the long response time, approximation errors, and/or noise amplification.
