Research on Voltage Regulation Strategy for Full Cable Distribution Networks Considering User Voltage and Power Quality

Aiming at solving the problem of insufficient voltage regulation capability at the end of distribution lines by existing reactive voltage regulation technologies, a reactive power and voltage adjustment strategy for distribution networks considering user voltage and power quality has been proposed. Firstly, the working principles of reactive voltage regulation strategies which are widely-used are analyzed. Secondly, a voltage quality evaluation method adapted to the voltage characteristics of the full-cable distribution network was proposed; At the same time, a reactive power and voltage adjustment application based on automatic voltage control(A VC) are proposed; Finally, the Reactive power and voltage adjustment strategy proposed is analyzed through an actual full-cable distribution network model.
