Abstract

Abstract: In order to solve the problem of grid connection and absorption of large-scale photovoltaic power stations, the grid connection scheme of photovoltaic power stations connected to the two-end flexible DC transmission system based on DC voltage, active power and AC voltage control is adopted. Using RTDS simulation software, a DC power distribution system model including a photovoltaic power station and two MMCs was constructed, and the operating characteristics of the system were analyzed in detail. The simulation results show that when the output power of the photovoltaic power station fluctuates or the DC load changes, the system can maintain stable operation.
