Abstract: Wind and photovoltaic power stations participate in voltage regulation control, so they can provide emergent reactive power support for power grids when necessary to meet the requirements of high power quality and low network loss. The paper expounds the principle and practical application of new energy AVC(Automatic Voltage Control) of regional power grids, and summarizes common problems of new energy AVC control grid access. This control method passes the comprehensive experiment of 35 kV new energy AVC substation accessing to the regional master station, demonstrates the effectiveness of functions such as curve release, closed-loop control and voltage follow-up, and has good follow-up and speediness in response.
Key words: new energy; automatic voltage control; closed-loop control
