Optimal microgrid´s protection coordination considering N-1 contingency and optimum relay characteristics
Popis výsledku v původním jazyce
There is a knowledge gap about the development of optimal coordination of microgrids, which considers all N-1 contingencies by using the smart selection of standard relay characteristics. This paper triesto fill such a knowledge gap by contributing to introduce a novel method to optimize the coordinationof microgrids’ directional overcurrent relays (DOCRs), which smartly selects the time-current characteristic of relays and considers all system topologies. Achieving an optimal protection scheme of micro-grids without any selectivity constraint under various topologies is the main purpose of this research.The proposed objective function of total operating time of DOCRs under various system topologies islinearizedastheTDSs.Thehybridheuristic-linearprogrammingalgorithms(HHLPAs)areusedtosolvethe mixed-integer non-linear programming (MINLP) problem. The decrease in the number of heuristic algorithm’s decision variables improves the performance of the proposed HHLPAs.The soft computing-based comparison of the hybrid genetic algorithm-linear programming (GA-LP) and the hybrid particleswarm optimization-linear programming (PSO-LP) is another contribution of this paper. About 80%decrease in the DOCRs’ operating time has been achieved by applying the proposed smart selection ofstandard relay characteristics (normally inverse, very inverse, and extremely inverse) in comparisonto use of just normally inverse curve based on existing methods. The satisfaction of coordinationconstraints of optimum relay settings is validated based on the DIgSILENT protection simulations.
