An Intelligent Controller for the Signal Generation of Solar Energy and Battery Storage Supported Multi-Level UPQC

Abstract

This study examines, the solar power and battery energy storage associated diode clamped five-level unified Power quality conditioner (5L-UPQC) to handle the PQ related problems. To eliminate the requirement of the complex transformations like abc, dq0, ?? , the ANN based control scheme with LMBP training method is adopted for the 5L-UPQC to produce the necessary reference signals for the voltage source converters (VSC’s). The prime goal of the proposed scheme is to maintain stable DLCV during load shifting, reduction of THD. In addition, the grid voltage distortions like sag, disturbance and swell were eliminated. The suggested method was demonstrated on two cases with several permutations of loads. However, to reveal the performance of the developed method, the comparison is carried out with the PIC and SMC.
