Abstract
There is more wind with less turbulence offshore compared with an onshore case, which drives the development of the offshore wind farm worldwide. Since a huge amount of money is required for constructing an offshore wind farm, many types of research have been done on the optimization of the offshore wind farm with the purpose of either minimizing the cost of energy or maximizing the total energy production. There are several factors that have an impact on the performance of the wind farm, mainly energy production of wind farm which is highly decided by the wind condition of construction area and micro-siting of wind turbines (WTs), as well as initial investment which is influenced by both the placement of WTs and the electrical system design, especially the scheme of cable connection layout. In this paper, a review of the state-of-art researches related to the wind farm layout optimization as well as electrical system design including cable connection scheme optimization is presented. The most significant factors that should be considered in the offshore wind farm optimization work is highlighted after reviewing the latest works, and the future needs have been specified.
Highlights
Due to the increasing demand for clean energy, the utilization of prolific renewable energy such as wind energy becomes more and more popular
A review work has been done based on earlier works related to the wind turbine (WT) micrositing and electrical system optimization of the offshore wind farm
Most of the recently published works for WT micro-siting have been done based on a coordinate model, which has been demonstrated to be a better model than the grid model
Summary
Due to the increasing demand for clean energy, the utilization of prolific renewable energy such as wind energy becomes more and more popular. The wind speed deficit calculation is a complex process which is related to the micro-siting of WTs, the wind condition as well as the control strategy of WTs. The analytical model of wind in the wake involves a mass of constraints that make the wind farm layout optimization problem (WFLOP) as an NP-hard (nondeterministic polynomial time) optimization problem [2]. The analytical model of wind in the wake involves a mass of constraints that make the wind farm layout optimization problem (WFLOP) as an NP-hard (nondeterministic polynomial time) optimization problem [2] For solving such a problem, the classic optimization algorithm would flop because of excessive computation time. The above three parts composed the main content of the electrical system optimization of the offshore wind farm.
