“…Microgrids are designed and operated for many applications, such as remote communities, distribution feeders, commercial buildings, ships and so on (Department of Energy Office of Electricity Delivery and Energy Reliability, 2012; Meegahapola & Duane, 2016). Microgrids are also classified based on the configuration; alternating current (AC) microgrids, direct current (DC) microgrids, and AC-DC hybrid microgrids (Tan, Meegahapola, & Muttaqi, 2014).…”

Electricity networks are evolving rapidly with the large-scale integration of power electronic (PE)-interfaced distributed renewable energy resources (DRERs). With this rapid deployment of PE-interfaced renewables, requirements set for the PE-interfaced DRERs have also evolved to maintain grid security and reliability. Fault ride-through (FRT) is an essential requirement which should be adhered by DRERs, which will ensure security and reliability of the power system during grid faults. This paper critically reviews the existing FRT standards (grid-code requirements) and FRT strategies implemented/ proposed for major DRERs, such as wind energy conversion systems (WECSs), solar photovoltaic (PV) systems, and microgrids. According to the review, robust FRT strategies are implemented/proposed DRERs, however, the FRT grid codes are presently developed with the perspective of both synchronous and renewable generation operating in the power system. However, this current approach should be augmented considering 100% PE-based renewable energy scenarios, and emerging issues, such as high penetration of PE-interfaced small-scale renewable generators (e.g., domestic solar-PV systems) and recurring grid faults, to achieve a sustainable renewable energy future. This article is categorized under: Concentrating Solar Power > Systems and Infrastructure Wind Power > Systems and Infrastructure Photovoltaics > Systems and Infrastructure K E Y W O R D S distributed renewable energy resources (DRERs), fault ride-through (FRT), gridcode requirements, microgrids, power electronic converters, solar-PV, wind energy conversion systems (WECSs)

This paper describes a novel strategy for microgrid operation and control, which enables a seamless transition from grid connected mode to islanded mode, and restoration of utility supply, without loss or disruption to loads sensitive to frequency or phase angle dynamics. A simulation study is conducted on a microgrid featuring inverter connected renewable generation, and power electronic interfaced loads. Therefore, the microgrid inherently has low inertia, which would subsequently affect the dynamic characteristics of the microgrid, in particular during mode transition. The microgrid is controlled by means of synchrophasor data to achieve synchronous island operation, enabling the microgrid to track the utility frequency and phase angle. The simulation includes synchrophasor acquisition and telecoms delays, allowing for detailed investigation of the microgrid dynamics under various mode transition scenarios, including the risk of commutation failure of the inverter sources. The proposed method is demonstrated to successfully maintain a microgrid in synchronism with the main utility grid after the transition to islanded mode without significant impact on various equipment connected to the microgrid. Thus, synchronous island operation of low inertia microgrids is feasible. This study also showed that utility supply could be seamlessly restored if the microgrid is operated as a synchronous island.
