Optimal integral planning of primary-secondary distribution networks via MOEA

This paper highlights an application of a restricted population based multi-objective seeker-optimization-algorithm (MOSOA) for designing integral power distribution system (IPDS) including the grids - the primary(PG) and secondary (SG). The proposes scheme considered both the PG and SG separately along with the factors that couple both problems (PG & SG) such as sharing of the common right of way, use the same poles etc. including other factors that shows significant effect on total investment cost. The proposed planning methodology uses a contingency-load-loss index (CLLI) for reliability evaluation, does not depends on the failure rate and fault repair duration of branches. The proposed approach performance is assessed on a real case of a 75-electrical node primary-secondary residential distribution network, considering real-time design practices. The efficacy of the proposed planning model is shown by a qualitative comparison with NSGA-II.
