Optimal Overcurrent Relays Coordination in the Presence Multi TCSC on Power Systems Using BBO Algorithm

Abstract

Optimal coordination of Inverse Definite Minimum Time (IDMT) direction overcurrent relays in the power systems in the presence of multiple Thyristor Controller Series Capacitor (TCSC) on inductive and capacitive operation mode on meshed power system is studied in this paper. The coordination problem is formulated as a non-linear constrained mono-objective optimization problem. The objective function of this optimization problem is the minimization of the operation time (T) of the associated relays in the systems, and the decision variables are: the time dial setting (TDS) and the pickup current setting (IP) of each relay. To solve this complex non linear optimization problem, a variant of evolutionary optimization techniques named Biogeography Based Optimization (BBO) is used. The proposed algorithm is validated on IEEE 14-bus transmission network test system considering various scenarios. The obtained results show a high efficiency of the proposed method to solve such complex optimization problem, in such a way the relays coordination is guaranteed for all simulation scenarios with minimum operating time. The results of new relay setting are compared to other optimization algorithms.

Protective Relaying Coordination in Power Systems Comprising Renewable Sources: Challenges and Future Insights

“…The authors of [200] proposed the BSA for solving the DOCR coordination problem that was formulated as a NLP problem as well as a mixed integer NLP issue; the results proved the superiority of BSA over some optimization techniques such as DE, PSO, black hole, electromagnetism-like mechanism, biogeographybased optimizers, and harmony search. Meanwhile, enhanced BSA is implemented in [201], the Box-Muller harmony search algorithm is implemented in [202], the ABC algorithm is introduced in [153], biogeography-based optimization is presented in [203], non-dominated sorting GA-II is presented in [176], an algorithm of improving group search optimization is proposed in [204], and ant colony optimization algorithm is used in [205]. In addition, the stochastic fractal search algorithm [206] is applied to optimize relay settings.…”

Robust coordination of directional overcurrent relays using a matheuristic algorithm

“…Although this approach is generally better than treating the problems separately, it still does not model the real coupling between the variables. (iv) Joint Ip/TMS tuning - [3,4,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]: In these approaches, TMS and Ip are set jointly, through an optimisation algorithm. Taking into account the non-linear nature of the problem, metaheuristic methods such as genetic algorithms (GAs), particle swarm optimisation (PSO), and differential evolution (DE) are commonly employed.…”
