Abstract:

High Voltage Direct Current (HVDC) transmission has provided a variety of possibilities for renewable energy resources and regional substations to boost power supply reliability and operational flexibility. To accommodate this development, the Modular Multilevel Converter (MMC) has been pervasively selected as a potential converter solution for HVDC applications due to its modularity and scalability. However, several technical challenges can hamper their practical applications and deployment, especially in modelling, controlling, and protecting the MMC-HVDC grids, since conventional control schemes struggle to achieve DC fault protection, converter energy balance, and DC Fault Ride Through (DC-FRT) capability. As a result, a novel control structure is proposed to ensure a proper dynamic response, balance arm and leg internal energies, minimise oscillations in DC, and offer DC-FRT capability alongside Static Synchronous Compensation (STATCOM). The result analysis under normal and pole-to-pole DC fault is done in MATLAB/Simulink to validate the proposed control scheme.
