“…The ant colony algorithm finetunes the coefficients of the PI controller to realize the optimal dynamic management of STATCOM. Reference [18] proposed a self-tuning PI controller that uses particle swarm optimization technology to adjust the controller gain. This algorithm takes into account the global gain and the adjustment of previous gains, and can obtain the desired gain very effectively.…”

The distribution static synchronous compensator (D-STATCOM) has the characteristics of non-linearity, multivariable and strong coupling. Based on the analysis of the D-STATCOM mathematical model, in order to improve the performance of the linear active disturbance rejection controller (LADRC), solve the coupling problem between the d-axis and q-axis current and improve the dynamic tracking response speed and anti-interference ability. A controller with LADRC that compensates the error of the total disturbance is proposed, and the stability of the improved first-order LADRC is proved by the Lyapunov stability theory. Then the output of the full interference channel is corrected to improve the antiinterference ability of the system and the interference observation ability of the linear extended state observer (LESO) to high-frequency noise. Through the analysis of the Bode diagram in the frequency domain, compared with the traditional LADRC, the improved LADRC proposed in this paper has better anti-interference performance. Finally, the improved first-order LADRC is used to replace the traditional D-STATCOM control strategy for current inner loop control, which effectively reduces the disturbance observation error of LESO. The experimental results show that the improved LADRC control performance is better than the proportional integral (PI) controller, and it has better tracking performance and antiinterference performance.

<p>This paper presents the application of modular multilevel converter (MMC) as a static compensator (STATCOM) for reactive current control. The current control is mostly achieved using proportional controller, proportional-integral (PI) controller, and hysteresis controller among others. PI controllers have the advantage of low harmonics and small variations. However, due to the PI controller’s dependency on the system parameters and also due to the variations within the MMC during capacitors voltage control, variation in the MMC performance during the STATCOM non-ideal operations occur. To mitigate this, an improved performance of MMC will be presented using vector-based compensation concept. The proposed control will be introduced to depress the effect of the dynamics of the MMC based STATCOM non-ideal variations considering the impact of the voltage disturbance. This will be achieved by the introduction of voltage variables to subtract the transient variations from PI controllers’ outputs at the grid-interface; thus, improving the performance.</p>

“…It is clear that the tracking performance of current and power factor are dependent on the characteristic of the current inner loop. The stability and anti-interference characteristic of system is guaranteed by voltage outer loop, using which the DC side output voltage is kept to a constant [4][5][6][7]. Design strategy of the PI parameter gains of dual closed-loop is an important issue to assure the static and dynamic characteristics of the three-level VSR [8][9][10][11].…”
