چکیده
Abstract For the overvoltage problem brought by access of high-penetration photovoltaic power plants to low-voltage distribution network, this paper chooses deal with it using reactive regulation capability plant inverters, which reduces equipment investment in line voltage regulation. Based on theory inverter, a finite set model predictive direct control method is proposed constructing virtual vector, taking single-phase cascaded 2H bridge grid-connected inverter as an example, realize independent active and power. By setting different reference values, can be made have two functions: per-unit factor during overvoltage. Finally, modes operation are verified Simulink simulation, verification example shows that limit deviation within 7% meet requirements regulations.
