Implementation of ACO technique for load balancing through reconfiguration in electrical distribution system

Abstract

Network reconfiguration in electrical distribution system is the process of changing the status of tie or sectionalizing switches, i.e., open or closed status to alter its topological structure. The proposed work attempts to reconfigure the system to balance loads while maintaining system radiality, using Ant Colony Optimization Technique. The burden of over loaded feeders is reduced by shifting partial loads to relatively lightly loaded feeders through reconfiguration of the system structure. The proposed technique provides various feasible solutions to balance loads on the feeders along with Graph Theory.

Mitigating unbalance using distributed network reconfiguration techniques in distributed power generation grids with services for electric vehicles: A review

“…The branch can be either a line section, a tie line with the sectionalizing switch or a transformer. Similar work (Babu, Kumar & Teja 2013;Babu et al 2014;Babu et al 2017;Ji et al 2017;Nara, Mishima & Satoh 2003;Xiaoling et al 2004;Yuehao et al 2016;Zhou, Wang & Liu 2017) optimized the Load Balancing Index (LBI) as the feeder load balancing index at the system level. The feeder level LBI is shown in equation ( 4), where n is the number of primary feeders, i Y is the normalized loading on the feeder (actual loading divided by the loading limit) and Yis…”

“…The MPSO algorithm with interactive fuzzy method reached the global optimum solution over other methods (GA, and PSO) and recommend an optimal switch configuration. The ant colony optimization (ACO) method in (Babu et al 2014;Yuehao et al 2016) is used to optimize the number of sectionalizing and tie switches for minimizing load balancing Index (LBI). The feeders are balanced by shifting partial loads from overloaded feeders to under loaded feeders using switches in radial network along with graph theory.…”

Coordinated photovoltaic re-phasing: A novel method to maximize renewable energy integration in low voltage networks by mitigating network unbalances

“…Further, many researchers have used different optimization techniques to mitigate voltage unbalance and power loss using DFR techniques. These include heuristic search [24], ant colony optimization [25,26], genetic algorithm [24,[27][28][29], incremental algorithm [30], fuzzy approach [31,32], colored Petri net algorithm [33,34], second-order cone programming [35], mixed-integer linear programming [36,37], and hybrid bacterial foraging -spiral dynamic [38] algorithms. The time-varying nature of loads and distributed generators, and their uneven distribution in the network cause LV feeders to often become unbalanced.…”
