Abstract

With the inherent benefits of high-voltage direct current (HVDC) transmission systems like long-distance high-power transmission with lesser losses and costs, easy integration of renewables, and others, increased presence of DC-AC grids is expected. One of the consequences of increased presence of power electronics is the reduced inertia in the grid, which is an emerging concern. Moreover, the long length of AC transmission lines result in the presence of weak grids (with low short-circuit ratio). To address these concerns, an advanced control algorithm is proposed to control the modular multilevel converter (MMC) based HVDC substation that is connected to a low-inertia weak-grid. The algorithm is based on optimization of control states like frequency, capacitor voltages, active power, and currents in the MMC. The performance of the proposed algorithm is validated in PSCAD/EMTDC to show the effectiveness of the proposed strategy.
