摘要
Abstract
Active power exchange between different AC zones can be controlled precisely by VSC power controlling. A droop control strategy was proposed which could achieve balanced load ratio between connected AC distribution zones. Firstly droop gradient was calculated according to transformer capacity of different AC zones. And then power reference of droop control was dynamically adjusted during operation of each voltage source converter. Load ration of different AC zones could be balanced in real time by this method. The electromagnetic transient simulation method of AC/DC distributon system was built in PSCAD for simulation analysis,which verify the effectiveness of the proposed methed.关键词
