Improved Control Strategy of MMC–HVDC to Improve Frequency Support of AC System

Improved Control Strategy of MMC–HVDC to Improve Frequency Support of AC System

With the continuous development of power electronics technology, variable-speed offshore wind turbines that penetrated the grid system caused the problem of inertia reduction. This study investigates the frequency stability of synchronous, offshore wind-farm integration through a modular-multilevel-...
