Synthesis of ADRC and its Application to an Electrical Power System

As the power system becomes smarter, the difficulty of control is also increasing. Since, load frequency and voltage stability is an important power quality index in power system, any sudden load disturbance will cause the system load frequency and voltage deviation, and as the power system becomes more complex. However, the stability and reliability of the smart power grid are facing great challenges caused by the intermittency and randomness of renewable energies. Nowadays, it is necessary to find a more appropriate control strategy and techniques. Due to the superior anti-interference and anti-coupling ability of the active disturbance rejection control (ADRC), novel applications of this control technique have been developed in smart system. This paper presents firstly a synthesis of ADRC and then it discusses some important applications of ADRC in this field.
