Low voltage ride through capability of fuel cell generation system connected to low voltage network
2011 IEEE Conference on Clean Energy and Technology (CET), 2011New grid code is expected to require distributed generation units operating parallel with the low voltage grid to ride through low voltage event and at the same time injecting reactive current into the grid. The paper discusses and highlights the problems that could arise and explores the solutions to mitigate these problems.

The total real power injected by distributed renewable energy sources (RES) in the low voltage (LV) grids can cause voltage rise effects during light load scenarios. Integrating RES in microgrid architectures can result in improved power quality of the electrical grid, by avoiding the voltage rise effect from occurring and also by providing ancillary ...

Low voltage ride-through enhancement in DFIG-based wind turbine
2016 IEEE Electrical Power and Energy Conference (EPEC), 2016Wind farms are regarded as large-scale power plants with interconnected systems, where all systems interact with each other to improve the efficiency of the plant and thus enhance the quality of the output power. However, the conventional centralized controller is inappropriate for such plants.

Low voltage ride through for a wind turbine based SCAG
2015 3rd International Renewable and Sustainable Energy Conference (IRSEC), 2015This paper develops a control strategy for a large wind turbine based on the squirrel cage asynchronous generator (SCAG). In addition, the transient behavior during Low Voltage Ride Through (LVRT) of the system is studied. To this end, the wind turbine connected to the grid is controlled in such way to inject maximum power into the grid and provide a ...

Low voltage ride through capability of gas engine driven units
22nd International Conference and Exhibition on Electricity Distribution (CIRED 2013), 2013Recent developments in European grid code regulations demand the inclusion of decentralized generation (DG) into their requirements. Gas-engine-driven generators, as a part of Europe’s DG, need to comply with these requirements; and therefore procedures to receive admission are formed.

Effect of Low Voltage Ride Through Technologies on Wind Farm
2007 IEEE Canada Electrical Power Conference, 2007Doubly fed induction generators (DFIG) offer many advantage when used with wind turbines. Given their configuration, they are particularly sensitive to grid faults. As many countries now require wind turbine generators to remain connected to the grid during faults, low voltage ride through solutions are being developed to fulfill this new requirement ...

Low Voltage Ride-Through protection techniques for DFIG wind generator
2013 IEEE Power & Energy Society General Meeting, 2013Due to the rapid increase of penetration level of wind generation connected directly to the bulk power system grid, a new grid codes have been issued that require Low-Voltage Ride-Through (LVRT) capability for wind turbines so they can remain online and support the electric grid post fault events instead of instantaneous tripping.

Improving Microgrid Low-Voltage Ride-Through Capacity Using Neural Control
IEEE Systems Journal, 2020In this article, a neural sliding-mode linearization controller is proposed to regulate the generated active and reactive power for each distributed energy resource in a microgrid. The developed controller is based on recurrent high-order neural network identification, trained online with an extended Kalman filter learning algorithm.
