“…During the turbine rotation, the relative velocity will be updated by calculating the bound vortices at each time step; one can calculate the lift and drag at each time step and thus to obtain the tangential force, t F , with which, the mechanical power output of the turbine can be obtained as follows, m t d P Fr dt (12) where , t F , and r denote the turbine azimuth angle, the tangential force, and the turbine radius, respectively.…”

“…The development of in-stream tidal current turbine farm model is still in the infancy stage. Studies have been conducted to estimate energy potentials in a number of oceanic countries, such as Brazil [12], Canada [13] and [14], India [15], Spain [4], the United Kingdom [16], and the United States [17]. These studies have been used by governmental agencies to determine whether and how to build in-stream turbine farms.…”

This paper is based on a recent paper presented in the 2007 IEEE SMC conference by the same authors, discussing an approach to predicting energy output from an instream tidal turbine farm. An in-stream tidal turbine is a device for harnessing energy from tidal currents in channels, and functions in a manner similar to a wind turbine. A group of such turbines distributed in a site is called an in-stream tidal turbine farm which is similar to a wind farm. Approaches to estimating energy output from wind farms cannot be fully transferred to study tidal farms, however, because of the complexities involved in modeling turbines underwater. In this paper, we intend to develop an approach for predicting energy output of an in-stream tidal turbine farm. The mathematical formulation and basic procedure for predicting power output of a stand-alone turbine is presented, which includes several highly nonlinear terms. In order to facilitate the computation and utilize the formulation for predicting power output from a turbine farm, a simplified relationship between turbine distribution and turbine farm energy output is derived. A case study is then conducted by applying the numerical procedure to predict the energy output of the farms. Various scenarios are implemented according to the environmental conditions in Seymour Narrows, British Columbia, Canada. Additionally, energy cost results are presented as an extension.

A tidal current turbine is a device for harnessing energy from marine currents, and functions in a manner similar to a wind turbine. A group of tidal current turbines distributed in a site in ocean is called a tidal turbine farm. Among all tidal current energy extraction schemes, turbine farm is regarded as among the most promising turbine configurations; in fact, of turbine farms are extensively employed in the wind power industry. Wind farm planning and modeling approaches cannot be fully transferred to tidal farms, however, because of the complexities involved in modeling the underwater tidal turbine. This study develops a framework for planning a tidal turbine farm system with vertical axis tidal current turbines. This framework is intended to be used by energy planners in the early design stage. An approach for selecting the optimal design among alternative tidal turbine farm designs is proposed whereby the attractiveness of the alternatives is evaluated based on cost effectiveness. Where possible, experience gained from analysis of existing offshore wind farms is applied. The state of the art of tidal turbine design and wind farm planning are reviewed, and a planning framework for selecting the optimal tidal farm design is provided by identifying the important mathematical modeling procedures and elements. Considering the particular design of the vertical axis tidal turbine, a simplified relationship of turbine distribution and turbine farm efficiency is developed. As a case study, numerical simulation results are presented for environmental conditions offshore of British Columbia, Canada.

Abstract-This paper focuses on connecting tidal turbine farms to the French electrical grid. One tidal farm is considered, which is the commercial farm. The connection state is defined by the active power and the voltage at the common coupling point (PCC, also called the delivery point), and is constrained to respect the Grid Code requirements. In order to ensure this connection, this paper develops an active power control framework constrained to the requirements of the Grid Code. This framework is based on the solution of a quadratic programming problem to meet the power demand at the PCC while respecting the requirements of the Grid Code in different plans. As the farm will be installed at the ocean depths, several kilometers of cables will be used to transport the electricity up to the PCC then the power losses are also taken into account in this framework. This framework is applied to a commercial farm with realistic data to show his relevance and effectiveness.
