Item Layout optimisation of wave energy converter arrays(2017) Mercadé Ruiz, Pau; Nava, Vincenzo; Topper, Mathew B.R.; Minguela, Pablo Ruiz; Ferri, Francesco; Kofoed, Jens Peter; RENOVABLES OFFSHOREThis paper proposes an optimisation strategy for the layout design of wave energy converter (WEC) arrays. Optimal layouts are sought so as to maximise the absorbed power given a minimum q-factor, the minimum distance between WECs, and an area of deployment. To guarantee an efficient optimisation, a four-parameter layout description is proposed. Three different optimisation algorithms are further compared in terms of performance and computational cost. These are the covariance matrix adaptation evolution strategy (CMA), a genetic algorithm (GA) and the glowworm swarm optimisation (GSO) algorithm. The results show slightly higher performances for the latter two algorithms; however, the first turns out to be significantly less computationally demanding.
