The performance optimization of the load frequency control problem for two-area interconnected power system is investigated by employing the gravitational search algorithm based linear active disturbance rejection control approach. Firstly, the load frequency control problem of a two-area power system with two identical non-reheated turbine units is formulated, taking into account the external step disturbance and parameters perturbation. Then, the essentials of the second order process oriented linear active disturbance rejection control approach are presented, where the parameters optimization procedure based on the gravitation search algorithm is proposed. Finally, the effectiveness of the proposed approach in the load frequency control problem is validated by the given extensive simulation examples. The disturbance rejection ability and the robustness with respect to the parameter perturbation of the proposed approach are also demonstrated.

Disturbance Rejection Control

Load frequency stability is an important power quality index in power system, any sudden load disturbance will cause the system load frequency deviation, and as the power system becomes more complex, the difficulty of control is also increasing, it is necessary to find a more appropriate control method. Considering that the load frequency control system model has the characteristics of multi-variable and strong coupling, combines the superior anti-interference and anti-coupling ability of the active disturbance rejection control, a novel scheme for power system load frequency control was presented based on the principle of active disturbance rejection control and effective open-loop transfer function. The simulation results show that the proposed method is simple tuning and strong decoupling ability, and provides a successful control of load frequency.

This paper studies the load frequency control (LFC) problem for hybrid power system (HPS) with renewable energy technology. The goal is to attenuate the frequency deviation due to changing load demand, fluctuating wind and varying solar radiation. Two typical HPSs are considered in the paper: one with abundant wind energy and the other with solar energy. Active disturbance rejection control (ADRC) method is used to design the load frequency controller. Simulation results show that ADRC provides higher reliability and stability for the studied HPSs than conventional PI control.

Tie Line

To ensure the safe operation of an interconnected power system, it is necessary to maintain the stability of the frequency and the tie-line exchanged power. This is one of the hottest issues in the power system field and is usually called load frequency control. To overcome the influences of load disturbances on multi-source power systems containing thermal power plants, hydropower plants, and gas turbine plants, we design a linear active disturbance rejection control (LADRC) based on the tie-line bias control mode. For LADRC, the parameter selection of the controller directly affects the response performance of the entire system, and it is usually not feasible to manually adjust parameters. Therefore, to obtain the optimal controller parameters, we use the Soft Actor-Critic algorithm in reinforcement learning to obtain the controller parameters in real time, and we design the reward function according to the needs of the power system. We carry out simulation experiments to verify the effectiveness of the proposed method. Compared with the results of other proportional–integral–derivative control techniques using optimization algorithms and LADRC with constant parameters, the proposed method shows significant advantages in terms of overshoot, undershoot, and settling time. In addition, by adding different disturbances to different areas of the multi-source power system, we demonstrate the robustness of the proposed control strategy.
