Abstract: In this research, a recently developed meta-heuristic technique in the field of nature inspired algorithms (NIAs), namely, the hermit crab shell exchange (HCSE) algorithm is applied on the transmission network expansion planning (TNEP) problem. In this work, HCSE is applied with contingency-based security constrained TNEP (SeTNEP) with DCOPF for standard Graver's six bus test system and Brazilian 46 bus test system. Also TNEP with ACOPF for standard Graver's six bus test system and IEEE 24 bus test system is considered. The outcomes were evaluated against other renowned algorithms and deterministic methods that are available in the literature. The results reveal that the HCSE algorithm has accurately and proficiently solved the TNEP problem in these test scenarios.
