The FREEDM (future renewable electric energy delivery and management) system is a smart distribution system that facilitates seamless integration of high-penetration DRER (distributed renewable energy resources) and DESD (distributed energy storage devices) with the existing distribution system. Protection schemes have been proposed to detect the overcurrent faults throughout the FREEDM system, according to its requirements. In this paper the time inverse directional over current protection coordination scheme is developed as a backup protection when the primary protection communication failed. The proposed scheme is applied to FREEDM network using conventional mathematical model. To speed up the fault clearing time without coordination loss, the settings of the proposed relays in the two directions are minimized using genetic algorithm. The developed methods are validated using ETAP software. The results ensure that the faults throughout the FREEDM system sections are detected and the relays tripping time are minimized.

“…However, and unlike the PSO, it does not pay much attention to the cooperative behavior of all groups. Many other algorithms have also been incorporated in solving the DOC relays coordination problem, such as the Gravitational Search Algorithm [29], Biogeography-based Energies 2019, 12, 4115 3 of 16 optimization [8], Electromagnetic Field Optimization [30], Firefly algorithm [31] and the Whale Optimization Algorithm [32].…”

Distributed, generation-based micro-grids are increasingly being used in the build-up of the modern power system. However, the protection of these micro-grids has many challenges. One of the important challenges is the coordination of directional overcurrent (DOC) relays. The optimization of the coordination of DOC relays is considered a nonlinear programming problem with pre-defined constrains. In this paper, the problem of the optimal coordination of DOC relays is solved using a multi-verse optimization (MVO) algorithm which is inspired from cosmology science. The proposed algorithm is tested by applying it to Institute of Electrical and Electronics Engineers (IEEE) 3 bus and IEEE 9 bus networks. The performance of the proposed algorithm is compared with the particle swarm optimization (PSO) algorithm when applied to both networks. All results show that the performance of the MVO algorithm is better than PSO in terms of its reduction of both the overall operating time (OT) of DOC relays and the computational burden of the computer solving the optimization problem.

“…Electromechanical or microprocessor-based relays have standard range of CTI (generally, between 0.2 and 0.5 sec depending on the type). In the literature normally fixed values are adopted, as 0.3 s, when the calculation is performed (Tjahjono et al, 2017;Elmitwally et al, 2015;Meskin et al, 2015;IEEE, 2001;Noghabi et al, 2010). An adequate CTI depends on several considerations such as: start time of elements (reaction), possible delay of the upstream relay, error margin due to Current Transformer (CT) saturation, digital relays operating time and relay contacts operating time.…”

Directional Overcurrent Relays can be dynamically and quickly configured using optimization techniques making the electrical network more resilient. In this work, the directional overcurrent relay coordination is modeled as mixed integer non-linear problem that minimizes the sum of relays operating times and maximizes their coordination intervals. To solve this, the use of Multiobjective Canonical Differential Evolutionary Particle Swarm Optimization is proposed in this work. The effects of different probabilistic distributions (normal, uniform, triangular and qui-squared ones) to initialize the decision variables (time dials, pickup currents, curves and indexes) are also discussed in this work. With the proposed method a reduction in convergence speed of more than 50% can be obtained when the adequate probabilistic distribution is used. The decrease in time can also be enhanced if a different acceptable reduction of the Coordination Time Interval is considered resulting in different and robust solutions.
