“…Hence, to reduce the parameter tuning of the proportional and integral controller, a control scheme with DC link voltages is controlled with an improved voltage balancing scheme using proportional and integral controllers, and the inner current controller is regulated with SMC control [9] and as shown in Figure 2. The improved two-loop PI control-based control scheme decreases the difficulty [15]- [20]. The multilevel inverter-based DSTATCOM is highly coupled with nonlinearity and multivariable structure.…”

In this article, the robust nonlinear controller for cascaded H-bridge-based distributed static compensator (DSTATCOM) with input-output linearization and sliding mode control scheme using an improved voltage balancing scheme is presented. The feedback linearization method and sliding mode control scheme are used to cancel nonlinearities and deal with invariant stability due to mathematical modeling uncertainties due to DSTATCOM parameter and external load disturbance. The improved voltage balancing is used to balance the voltages of the DC side capacitor of DSTATCOM. The complete simulation studies are out to validate the control scheme based on the improved voltage balance integrated with sliding mode control under disturbances caused by the load changes and DSTATCOM parametric changes. The performance characteristics of the DSTATCOM with sliding mode controller are tested using the MATLAB/Simulink platform.

“…The research focuses on a reduced switch MLI that is managed by a soft computing ANN. Several power quality issues, such as voltage sag, voltage swell, power factor, harmonics, and voltage compensation restoration time are intended to be mitigated by this new configuration [11], [12]. The UPQC, a significant power conditioner designed to enhance power quality for consumers and utility points, is discussed in the paper's discussion of the importance of power systems.…”

This paper presents a cascaded h-bridge (CHB) multilevel inverter (MLI) based MLI based distribution static synchronous compensator (DSTATCOM). The main objective of this paper is to reduce source current harmonics in the distribution system by using a cascade H-bridge multilevel inverter (CHBMLI) as DSTATCOM with a proportional-integral (PI) controller. The PI controller compensates reactive power, reduces source current harmonics, and maintains the unity power factor in the distribution system. The conventional two-level inverter-based DSTATCOM has many disadvantages such as high total harmonic distortion (THD), and high switching stress power semi-conductor devices, suitable for only low-power applications. This paper to overcome these drawbacks by using MLI-based DSTATCOM. The proposed system simulations are verified in MATLAB/Simulink software. The verified results are source current, load current, and compensating current.
