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.

“…IT2FL controller is one of the artificial intelligence controllers which can overcome the uncertainty situation which the T1FL controller can't handle. IT2FL controller can be tuned easily to handle the nonlinear situations because it has strong learning ability and the ability to be adaptive with system parameters changing [42,43]. First, IT2FL controller was applied alone with control strategy to control the DSTATCOM device.…”

“…IT2FL is utilized in the instantaneous reactive power strategy to generate the reference current signals. This control strategy is used to control the three-level active neutral point clamped DSTATCOM device with special structure [42]. Interval type II fuzzy logic was utilized with least mean square control strategy to control the five-level cascade H-Bridge Multi Level Inverter (CHBMLI) DSTATCOM device and compare it with the PI controller [43].…”

The interval type II fuzzy logic controller (IT2FL) is a recent artificial intelligent technology which is applied in many aspects of electrical power engineering and controlling strategies these days. The improving of Distribution Static Synchronous Compensator (DSTATCOM) control algorithms is still ongoing, because the control strategy of DSTATCOM device is considered as a decisive factor which affects the performance of DSTATCOM device in enhancing the quality of power in the distribution grids. The improving process focuses in two main aspects the DC capacitor voltage response to the control system and the mitigation of the harmonics which are produced by the controlled and uncontrolled rectified loads. In this paper, the interval type II fuzzy logic controller (IT2FL) based the Unit Voltage Template strategy (UVT) is examined by the MATLAB program with two different ranges of input signals, and compared with the type I Fuzzy logic controller (T1FL). The IT2FL based UVT shows promising results in improving the deformed shape of source current waves in comparison with the other controllers.

“…The CHB-MLI is most preferred due to the complexity posed by the neutral point clamped and flying capacitor multilevel inverter [8]- [10]. The advantages of the CHB MLI are that any number of voltage levels can be realized with the addition of small voltage sources [11]- [13]. The cascaded multilevel inverter reduces the  ISSN: 2502-4752 Indonesian J Elec Eng & Comp Sci, Vol.…”

<span>In this paper, <span>a voltage source inverter is utilized as a distributed static compensator (DSTATCOM). The DSTATCOM is used for the elimination of harmonics caused by the nonlinear load. The reference currents of DSTATCOM were estimated with a synchronous reference frame (SRF). Conventionally, the SRF uses voltage, load current and filter current to compute the reference current to track desired source current for DSTATCOM. The sliding mode controller and feedback linearization are used to design the current controller. The feedback linearization technique and sliding mode control are used to cancel nonlinearities and offer invariant stability due to modeling uncertainties due to the DSTATCOM parameter and external load disturbance. The sliding mode controller requires a rigorous mathematical model of the system. To overcome this, an artificial neuro-fuzzy inference system (ANFIS) is devised for the control of DSTATCOM. The training data of the ANFIS controller is generated from the sliding mode controller algorithm. The overall system of DSTATCOM including the ANFIS algorithm is implemented in MATLAB/Simulink SimPower block sets. The simulated response of DSTATCOM was found to be improved and better than the sliding mode controller scheme.</span></span>
