The aim of this paper is to analyze the situations in which distributed power generation
systems (DPGSs) based on renewable energy sources (RESs) can be controlled when …

The trend toward Smart grid (SG) is increasing significantly by incorporating Distributed
Generators (DGs), which leads to new challenges, especially in protection systems. SGs …

Recently, the global concern for protection coordination is growing with the impact of
distributed generators connected to medium voltage distribution system. Effective protection …

Voltage sags may affect the accurate operation of several equipment connected to power
systems. A typical example is the doubly-fed induction generator (DFIG), which is often …

The assessment of compliance with grid codes requirements can be challenging for
researchers and (early stage) technology developers. To tackle this problem, a generic grid …

This paper analyzes the performance of a three-phase four-leg three-level neutral point
clamped based photovoltaic (PV) inverter which is connected to an unbalanced grid. The PV …

In the past, PI control algorithm and hysteresis control algorithm are not accurate in islanding
detection, which leads to poor control effect. In view of this problem, a single-phase inverter …

The fluctuation of grid variables affects the performance of the phase-locked loop,
considerably reducing the efficiency of grid energy injection or compensation currents …

Accepted: 3 August 2022 This paper is devoted to the development of a model of an
autonomous electric power system to study random processes of voltage, current and power …

The aim of this work is to analyze the dynamic behavior of inverters powered by renewable
energy sources (RES) operating under grid faults by means of a geometric point of view. To …
