“…Similarly in Mohaghegh, Venayagamoorthy, and Harley, PSO convergence analysis is provided using dynamical system approach in a one‐dimensional particle with transformation λ = ( c 1 + c 2 ) and u ( k ) = G best − x ( k + 1), for any particle x , which leads to

Y ((), k + 1) = italicAY ((), k) .

Here, the values of A and Y ( k ) are given as

A = ([], \begin{matrix} 1 & λ \\ - 1 & 1 - λ \end{matrix}),

normalY ((), k) = ({}, \begin{matrix} normalv ((), k) \\ normalu ((), k) \end{matrix}) .

Here, v ( k ) is the velocity of any particle at iteration k . The eigenvalues of this system are given as

λ_{1, 2} = 1 - \frac{λ}{2} \pm \frac{\sqrt{λ^{2} - 4 λ}}{2} .

“…But this approach is rather time consuming and can seriously suffer from a change in system operating conditions . In Kumari and Roy, PI controller gains of STATCOM are self‐tuned in order to achieve better voltage stability during disturbances. The study in Luo and Tang suggests a fuzzy‐based design to improve active/reactive current control loops.…”

Summary In this paper, a 13‐level cascaded H‐bridge medium voltage static synchronous compensator (STATCOM) has been designed for dynamic reactive power compensation. The dynamic performance of STATCOM has been enhanced by finding the optimal PI controller parameters using particle swarm and gravity search algorithms. In order to avoid capacitor voltage drifting, individual voltage balance control loop is introduced. The results of optimization methods on finding optimal PI controller parameters of STATCOM are verified and compared by simulation studies. The results show that each optimization technique renders effective tracking of both, DC‐link voltage reference values, direct current, reactive current, and reactive power reference values during the closed‐loop operation of STATCOM.
