Abstract
The voltage stability control method of AC/DC power system mainly focuses on a single regulation means,which leads to voltage region instability and large-scale fluctuation,so the voltage stability control method of AC/DC power system is studied.Firstly,the characteristics and rules of voltage distribution in AC/DC power system are revealed by dividing the voltage of AC/DC power system.After the voltage division,the mathematical model of the energy storage unit is constructed,the inertia characteristics of the DC distribution network are analyzed in detail,and the calculation method of the voltage stability load margin is determined to evaluate the stability level of the system.Finally,according to the voltage transient stability control output,the voltage stability control of AC/DC power system is realized.The experimental results show that:compared with the reactive power compensation method and the active power flow optimization method,the AC subnet voltage region of the AC/DC power system voltage stability control method is stable and has no large-scale fluctuation,so it has practical application value.关键词
