Power Quality Analysis and Enhancement for Grid Integration of Distributed Energy Resources: Photovoltaic and EV Charging Station using Active Power Filter

This paper propose the power quality analysis and enhancement for grid-integrated DER: case study of VSPP type photovoltaic and public EV charging station, that effect increase harmonics problem in the distribution grid. Therefore, harmonic voltage compensation process for grid connected-DER and charging station in power system is presented. The integrated method with low-pass filter and active filter are applied, both connected in series with the voltage harmonic detection method. This study using the theory of instantaneous reactive power and hysteresis. In order to study the change in voltage harmonics and to study the efficiency of the harmonic filter circuit. It has been designed using the average %THDv of supply voltage as a benchmark for comparative performance. According to the PEA standard and the system simulation results, it has been found that the designed series active power filter resulted in an average %THDv value are reduced 83.11% after compensation.
