Abstract: DSTATCOM (Distribution Static Compensator) is a shunt device. It is used to solve power quality problems in distribution systems. DSTATCOM is a shunt device used in correcting power factor, maintaining constant distribution voltage and mitigating harmonics in a distribution network. This paper presents a comparison of the performances of Type-1 and Type-2 Fuzzy logic controlled multilevel DSTATCOM for improvement of electric power, and corrects the power factor. The pulses for the five-level inverter are generated by Space Vector Modulation (SVM). The performance of Type-1 and Type-2 fuzzy logic controllers under load variation is evaluate using simulation results in MATLAB/Simulink.

Keywords: DSTATCOM; Fuzzy logic controller; Space Vector Modulation (SVM).

________________________________________________

* This paper is an extended version of the paper called “Design and simulation of five-level inverter based DSTATCOM using fuzzy logic”, published in the 6th International Renewable Energy Congress (IREC), 2015 pages: 1-6, DOI: 10.1109/IREC.2015.7110875. In the current paper, a novel control method based on type-2 fuzzy systems is used to improve the power quality. The control algorithm is presented and a set of simulations is carried out in order to prove the good performances of the proposed solution. We also compared the proposed method with the work presented in the IREC 2015.
