Application of statistical charts, multi-criteria decision making and polynomial neural networks in monitoring energy utilization of wave energy converters

Impact of extreme events on conversion efficiency of wave energy converter

“…Equation depicts the model equation. The detailed procedure of development of the model was described in the published work by Chakraborty and Majumder …”

“…The detailed procedure of development of the model was described in the published work by Chakraborty and Majumder. 42,43 The PNN model utilized for the estimation of UEF has 1 output, 83 numbers of hidden layers with 1011 nodes, and 24 numbers of inputs. N p is the number of submodels of the polynomial neural network topology identified by the GMDH algorithm (Equation 2c).…”

“…20,40,41 Swell has the potential to change the wave height, period, and regularity in the wave climate which may result in the irregular pattern of energy production. That is why all these factors or indicators were augmented to produce the utilization efficiency function 42,43 which was used to determine the capacity of converters in utilization of potential wave energy from the selected region. Section 3 explains the procedure adopted to represent the impact of extreme events on the capacity of WEC in extraction of available potential.…”

Application of AHP-VIKOR and GMDH framework to develop an indicator to identify utilisation potential of wave energy converter with respect to location

“…This method determines compromised solutions for a problem with conflicting criteria, which can help the decision makers to reach a final decision. The compromised ranking method of VIKOR consists of several steps (Chakraborty and Majumder, 2017c). The various J alternatives are denoted as a 1 , a 2 , …, a J .…”

“…In another paper (Chakraborty and Majumder, 2017c), the same objective was attempted by three different MCDM methods: AHP, DEMATEL-VIKOR, and DEMATEL-VIKOR-NFSDSS. Although AHP was utilised earlier for the same purpose, ensemble methods like DEMATEL-VIKOR and DEMATEL-VIKOR-NSFDSS were not used previously for the present objective.…”
