“…Examples of the use of this software in tidal evaluations are the study carried out in the East river in Manhattan (New York, USA) [16] or in the Nalón River [17], the approach used in the last one is shown in Figure 1. Additionally, each scheme implements its wetting and drying algorithm, eliminating or including different zones in the calculation while determining the position of the free surface.…”

A Review of Software Tools to Study the Energetic Potential of Tidal Currents

Tides can be a vast and predictable source of renewable energy. Due to the solar and lunar influx on our planet, they move large amounts of water periodically, and this energy can be harnessed using devices designed and positioned adequately, such as current turbines. However, the relation between the energy obtained with actual devices and the economic and environmental cost of their installation limits the practical application of these solutions. In order to optimize the design of this technology and achieve its successful installation and use, a detailed knowledge about the energy potential of tides at the specific location is necessary. This calculation is not easy and requires the use of specialized software tools. Currently, there is no specific software to evaluate the tidal currents energy potential, but there are more than a few codes able to calculate the hydraulic flow in rivers, estuaries and coastal regions. These programs are usually used for the calculation of pollutant dispersion and floods, but they can be adapted with more or less success. This paper reviews the available 1D, 2D, and 3D software tools with the aim of analyzing their functionality and their validity to evaluate the energy potential of tidal currents.

“…Following these optimistic estimates, plenty of energy companies are investing in different facilities to measure the energy that can be obtained from marine currents [3][4][5][6]. In this line of research the Spanish company INERSA S.L., with the collaboration of the Power Electronics Department from the Gijon Polytechnic School of Engineering and the Department of Fluid Mechanics from the Mieres Polytechnic School, is currently developing the HIDROCIMAR project that seeks, through the use of the marine currents, to cover for example, the demand for lighting of marinas.…”

The present project aims to design the control and monitoring system for a test bench that will help to calculate the power level that can be extracted from wind vertical axis hydrokinetic microturbines. The workbench includes a hydraulic system calculated to, through a recirculation between two tanks, achieve high fluid speed in the canal, and the monitoring and power electronics systems to adjust different hydraulic parameters and to control the operation of the microturbine under test, providing the necessary measures to obtain the power coefficient versus tip speed ratio (Cp-λ) curves of the microturbine which will help to extract the Maximum Power Point.

“…Recently, microturbine arrays in on-shore locations (even in low velocity sites), obtaining energy where it is consumed, is presented as a feasible alternative [6,7]. In this scenario, having an accurate estimation of the tidal flow energy potential to assess the correct array location, is a key factor to guarantee its feasibility [8].…”

Tidal current energy potential of Nalón river estuary assessment using a high precision flow model

2018

Obtaining energy from tide currents in onshore locations is of great interest due to the proximity to the points of consumption. This opens the door to the feasibility of new installations based on hydrokinetic microturbines even in zones of moderate speed. In this context, the accuracy of energy predictions based on hydrodynamic models is of paramount importance. This research presents a high precision methodology based on a multidimensional hydrodynamic model that is used to study the energetic potential in estuaries. Moreover, it is able to estimate the flow variations caused by microturbine installations. The paper also shows the results obtained from the application of the methodology in a study of the Nalón river mouth (Asturias, Spain).
