Optimum Placement of Distribution Generation Units in Power System with Fault Current Limiters Using Improved Coyote...

Area of Science:

• Electrical Engineering
• Power Systems Analysis

Background:

• Power systems face increased load and power losses due to rising demand.
• Distributed Generation (DG) integration helps reduce system load but can increase fault currents beyond breaker ratings.

Purpose of the Study:

• To determine the optimal placement of DG units and Fault Current Limiters (FCLs) in distribution systems.
• To minimize power losses and fault current levels in electrical grids.

Main Methods:

• Utilized the Improved Coyote Optimize Algorithm (ICOA) for optimal placement.
• Employed Electrical Transient Analyzer Program (ETAP) for system analysis.
• Applied a fuzzy-based multi-objective mechanism to enhance distribution system efficiency.

Main Results:

• The proposed method effectively reduced power losses.
• Fault levels were significantly decreased to acceptable levels.
• Optimal placement strategies were validated on IEEE 21-bus and 28-bus systems.

Conclusions:

• Optimal integration of DG units with FCLs is crucial for managing fault currents.
• The ICOA and ETAP-based approach provides an effective solution for enhancing power system performance.
• The fuzzy-based mechanism contributes to improved overall distribution system efficiency.
