LFC design with time-delay via LADRC and setting parameters based on genetic algorithm

In this paper, linear active disturbance rejection control technology is applied to deal with the time delay, which is transmitted from the control center to individual generation units based on the interconnected power system. LADRC can estimate real-time disturbance and compensate it quickly via making the two inputs from ESO synchronously. At the same time, the genetic algorithm is used for tunning parameters, so we can calculate the optimal value for each area. This method is applied to a single area and a four-areas power systems. The results show it can provide good control effect.
