Abstract
Electric power frameworks become intensely loaded because of the expanded power demand, and as a result, the power system faces great power losses and fault currents. The integration of Distribution Generation (DG) units plays a key role in minimizing the load pressure on a power system. DGs are transmitted with a high fault current, which surpasses the evaluations of circuit breakers. This paper presents various DG units’ optimal placement with Fault Current Limiters (FCLs) in different phases. The Improved Coyote Optimize Algorithm (ICOA) and Electrical Transient Analyzer Program (ETAP) are assessed for the proposed technique in terms of normal and faulty working status. Similarly, to enhance the efficiency of a distribution system, a fuzzy-based multi-objective mechanism is applied. The proposed method is employed on an IEEE 21-bus and 28-bus distribution system. The simulation analysis proved that the power losses and fault levels are reduced at an acceptable level.
Highlights
The attained outcomes are compared with Firework Algorithms (FWA), Bacterial Foraging Optimization Algorithm (BFOA), Harmony Search Algorithm (HSA), Taguchi Algorithm (TA)-based approach and Water Cycle Algorithm (WCA)
To enhance the voltage profile and to measure better placement of Distribution Generation (DG) in the distribution system, the Improved Coyote Optimize Algorithm (ICOA) algorithm is analyzed in this paper for an IEEE 28-bus system
Technique for allocating and sizing DGs is explored in different steps to show how fitness functions are defined as solutions to the generated issues
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. There has been an increase in power demand in the last decade, which means electric grids are heavily loaded [1,2,3]. This continuous pressure of load degrades the overall performance of the main power system. An economical and technical solution is required to handle load demands. Distribution Generations (DGs) are considered a fruitful solution to minimize the load pressure on a power system economically and technically because DGs improve system fidelity without the installation of new power plants and transmission lines [4,5,6]. This work studies the proper placement of DG units in the power system to decrease the power losses and fault current levels
