“…The optimal allocation of DGs with practical load models using optimization techniques based on novel multi-objective function is studied to enhance the system performance parameters (Bohre et al, 2016). The permissive overreach protection for clearance of fault rapidly in MV distribution including signal comparison schemes by performing short circuit calculations and electromagnetic transient using DIgSILENT PowerFactory is proposed (Borgnino,et al, 2018). The PV-Wind based renewable DGs planned in distribution systems using grasshopper optimization with operating time of overcurrent relay (Belbachir et al, 2021).…”

The utilization of renewable resources has been growing very fast worldwide recently to manage the increasing energy gap, but it also raises some challenges like protection issues, transient stability issues and security issues in the power system operation. Mainly, wind and solar photovoltaic renewable power generation sources are account for bulky renewable energy share. The transients in power systems including renewables are reduced and have recently attracted wide attention. The impact of renewables generation on power system transients should be effectively analyzed and evaluated to improve power system reliability, stability, operation and security. DIgSILENT Power Factory software is more powerful and useful for providing phasor of fundamental power frequency components better than other existing software’s; therefore, DIgSILENT Power Factory is proposed for modeling and analysis of the system.

Directional protection of transmission lines is an important feature in situations where short‐circuit direction must be correctly detected. The proper operation of this protection is highly dependent on phasor comparison techniques called polarisation methods. In practice, there are not clearly defined procedures to analyse and set polarisation methods. Hence, these methods are not normally studied in detail, so their effectiveness is often uncertain. For this reason, this work proposes a novel methodology for analysing the performance of polarisation methods, which includes criteria for the selection of the most appropriate methods and their settings according to each application. Particular phasor diagrams and angular statistics are used for the analysis, while a mathematical optimization problem is defined to determine the best settings of these methods. Based on the benefits that can be obtained, the methodology is intended to be considered as an effective strategy to ensure proper use of polarization methods. The methodology is applied in a portion of the Ecuadorian Transmission System which shows the possibility of studying the performance of polarisation methods. The selection and optimal setting criteria of these methods are also analysed providing opportunities to improve the initial performance of the protection system.
