Research on Power Flow Control of Renewable Energy Integration Based on Phase-shifting Transformers
摘要
Abstract
This article introduces the key technologies of the structure,parameters,and control principles of phase-shifting transformers,and elaborates on the application process of three typical application cases.In order to solve the problems of high voltage on the near end lines of distributed photovoltaic power generation in concentrated areas,as well as the load imbalance between lines with more photovoltaic power generation connections and other lines,we have developed a phase-shifting transformer and used key technology of phase-shifting transformer control to automatically adjust and control the voltage on both sides of the phase-shifting transformer.At the same time,by changing the phase angle of the line voltage,the magnitude and direction of the active power flow are changed,and the phase-shifting phase change is connected in series in the distribution network line to achieve voltage regulation at the end of the line;π is connected between two lines to achieve the function of controllable reversal of power flow between the two lines.Effectively solved the problem of load imbalance between power grid lines under the integration of renewable energy,and achieved the regulation function of"virtual power plants".关键词
