Abstract:
The distribution systems are transitioning from passive to active with the adaptation of storage, smart-grid, and distribution generation technologies. The reliability of the system can be improved due to the novel controllers, switches, and communication equipment. The common power quality issues are harmonics, signalling voltages, voltage fluctuations, voltage dips, voltage unbalance, power frequency variation, and induced low frequency voltages. These problems can degrade the output power level. To overcome the above problems through the power quality devices like Dynamic voltage restorer (DVR), distribution static compensator (DSTATCOM), and unified power quality conditioner (UPQC). The power quality mitigation technique includes the controller placement and it is named by Hybrid term of fuzzy-genetic controller (FG). Voltage sag, swell, and harmonics, such kind of problems have been analysed in this paper. The results are compared with the existing controllers. The proposed results are load voltage, injected voltage, and generated voltages are taken out. The performance of power quality is analysed through the multi compensating devices, and it is implemented in MMATLAB/SIMULINK. Thus the proposed system can yield the better results instead of the harmonic which is appeared in DVR, DSTATCOM, and UPQC are 0.008231%, 0.0831%, and 0.004308% respectively.
