Generic EMT Model for Real-Time Simulation of Large Disturbances in 2 GW Offshore HVAC-HVDC Renewable Energy Hubs

This paper proposes a Electro-Magnetic Transient (EMT) model of a 2 GW offshore network with the parallel operation of two Modular Multi-level Converter (MMC)—High Voltage Direct Current (HVDC) transmission links connecting four Offshore Wind Farms (OWFs) to two onshore systems, which represent a large scale power system. Additionally, to...

Analysis of Negative Sequence Current Control for MMC HVDC Transmission Systems

High Voltage Direct Current (HVDC) transmission system technology has recently attracted a lot of attention within the power system community. Modular Multilevel Converter (MMC) HVDC is the state of the art HVDC transmission technology, which contains hundreds and even thousands of submodules. It is the modularity, scalability and efficiency...

EMT model and dynamic power management strategy of an offshore renewable energy hub with local power-to-gas conversion

Given the urgency to shift to a cleaner energy mix, offshore wind energy is bound to be quickly deployed on a large scale in the next years. In order to meet the Paris Agreement, the current role-out rate of wind energy in the North Sea, that is 2 GW/year, needs to be increased to an average value of 7 GW/year over the period 2023-2040. This...

DC/DC Converters for Multiterminal HVDC Systems: Based on Modular Multilevel Converter

The increase in the energy demand has resulted in searching for new energy sources. Due to the increased prices of fossil fuels and the environmental issues, renewable energy sources has become popular in Europe. Renewable energy generation such as wind, solar and wave has point-to-point connections with the main grid. In order to minimize the...
