A number of control algorithms have been developed for load compensation using DSTATCOM. Choice of an algorithms according to the system therefore, becomes a topic of interest for the researchers. In this paper, nine control algorithms viz. instantaneous p-q theory, instantaneous modified p-q theory, synchronous reference frame theory, instantaneous p-q-r theory, average unity power factor (AUPF) theory, vectorial theory, instantaneous symmetrical components theory (ISCT), average global control theory (AGCT), and instantaneous global control theory (IGCT) are compared for different operating conditions of distribution system. The cases considered for system operation are nonlinear balanced load with balanced source, nonlinear unbalanced load with balanced source, nonlinear unbalanced load with unbalanced source, and nonlinear unbalanced load with non-sinusoidal balanced source. The performance of the system simulated on MATLAB platform is evaluated considering source current total harmonic distortion (THDI), total distortion content (TDC), and neutral current magnitude. The results show that ISCT, AGCT and IGCT control algorithms are able to compensate the load and improve system performance over other algorithms.
