Application Of A Novel Cheetah Optimization Algorithm For Conductor Placement In Hybrid Transmission Corridors: Addressing Field Effects And Structural Design Constraints

Abstract

The Indian power sector is rapidly expanding, relying on both Extra High Voltage Alternating Current (EHVAC) and High Voltage Direct Current (HVDC) transmission lines to meet growing electricity demands, especially for long-distance bulk power transfer. Optimizing hybrid systems combining EHVAC and HVDC is crucial for efficiency, stability, and cost reduction. Paper is on formulating an objective characteristic to optimize hybrid AC-DC transmission lines, deliberating the influences of electrical and magnetic fields, along with corona-brought on audible noise and radio interference. A new multi-goal characteristic has been evolved to simultaneously lessen electromagnetic discipline exposure by optimizing conductor configurations for each single-circuit and double-circuit hybrid transmission line. The Cheetah Optimization Algorithm (COA) addresses this constrained multi-objective trouble, assuring adherence to minimum electrical clearance standards and attaining the highest quality conductor arrangement that reduces electromagnetic area emissions. The effects of this optimization are corroborated via comparison evaluation with analogous studies completed in different international locations at one-of-a-kind voltage ranges, enhancing the validity and application of the proposed optimization method for hybrid EHV/UHVAC–HVDC transmission structures. The Cheetah Optimization Algorithm, a nature-inspired metaheuristic, shows promise in such optimization tasks, but its specific application to these hybrid systems in India requires further exploration.
