Abstract
In the present scenario, all over the world, electrical energy is produced by conventional or non-renewable energy supply system. These systems produce a large amount of atmospheric pollution. This predicament is principally conquered by the concentrated use of alternative or renewable energy system. The research work reported in the paper shows the profoundness of performance prediction and investigation of solar–tidal integrated renewable energy system using a different optimisation technique. The works on macro-level include a novel tidal–solar system in the coastal area of Cochin, India and modelling of tidal-solar energy system by the HOMER software. Duration of the project is assessed by a project management technique critical path method, optimisation of the HOMER software cost assessment result for the study area using teaching, learning-based optimisation, cuckoo optimisation and through the grasshopper technique, further reliability and life-cycle analysis of the system and result are validated by regression analysis.
