The Distribution Generation (DG) resources is increasing due to the global trend to electrified transportation and the need for more sustainable and cleaner power electrical grid. However, the integration of DG resources to the power network system increases the challenges of achieving reliable protection system due to the new dynamic and nature of fault currents. However, the traditional and existing overcurrent coordination scheme may fail to detect and clear the faults within the minimum time. Considering the impact of DG such as renewable energy resources on fault current level and location, this article introduces and verifies an optimal protection coordination scheme of Over Current Relays (OCRs) using nonstandard tripping characteristics and two optimization algorithms, Particle swap optimization (PSO) and Kalman Particle swap optimization (KPSO). The proposed optimal OCR scheme works on increasing the sensitivity and security of the power protection scheme by reducing the Total Operating Time (TOT) and the elapsed time of microprocessor in numerical relay. The proposed approaches are tested and evaluated on IEEE-9 bus equipped with PV system with different faults locations to investigate the effectiveness of the proposed techniques. The results introduce that the proposed optimal nonstandard scheme based on KPSO algorithm reduces the elapsed time and overall time of OCRs and outperformed the PSO algorithm. |
