With the increasing penetration of wind power, large-scale integrated turbine brings stability and security risks to power grid. For aggregated modeling large farms, it is crucial consider low voltage ride-through (LVRT) characteristics. However, in aggregation methods, approximate neglect behavior essential, which leads inevitable errors process. Moreover, lack parameters practice new challeng...

Low voltage ride through (LVRT) is a solution to increase the tolerance of distributed energy resources (DERs) against sags. However, possibility DERs trip according present grid codes exists. Such trips do not have substantial local effect but are essential for transmission systems with connected DER-penetrated distribution networks (DPDNs). This paper investigates an analytical framework see ...

Wind power generation is increasing rapidly in India and wind integration with the grid is considered as a promising source of energy, Double Fed Induction Generator (DFIG) being the most commonly used wind turbine generator, when integrated with the grid show challenges during grid faults. This paper focuses on the challenges faced by DFIG during the occurrence of voltage sags and the Low Volt...

This paper presents an active crowbar, constructed with silicon controlled rectifiers (SCRs), for doubly fed induction generator (DFIG)-based wind turbines to fulfill low-voltage ride-through (LVRT) requirements demanded by grid codes. By this design, not only the active deactivation of the costly IGBT crowbar, replacing the passive crowbar for this ability, can be achieved with the more cost-e...

With the continuously increasing penetration of networked microgrids (MGs) on local utility grid (UG), MGs face challenge to avoid system fault currents during low-voltage ride-through (LVRT). To solve this challenge, an active current limitation (AFCL) method is proposed with three parts: 1) a novel phase angle adjustment (PAA) strategy conducted relieve impact output current; 2) injection (CI...

Due to the high penetration of grid-connected photovoltaic (GCPV) systems, network operators are regularly updating grid codes ensure that operation GCPV systems will assist in maintaining stability. Among these, low-voltage-ride-through (LVRT) is an important attribute PV inverters allows them remain connected with during short-term disturbances voltage. Hence, equipped control strategies secu...

Traditionally, industrial countries have generated most of their electricity in large centralised facilities, such as fossil fuel (coal, gas), nuclear, large solar power plants or hydropower plants. Although these plants have excellent economies of scale, they usually transmit electricity over long distances and negatively affect the environment. More recently, a surge in the concerns over clim...

In this paper, the Unified Interphase Power Controller (UIPC) is utilized to protect synchronous generator in case of faults occurring transmission system. The UIPC not only maintains generator’s stability by keeping its load angle within safe operational limits but also prevents high-amplitude currents from flowing through stator windings. This allows for more loading on without compromising s...
