Optimizing offshore wind farms electrical system design and reactive power provision
article
In this paper, electrical system design for the offshore transmission system of a wind farm has been optimized such that the grid code compliance has been ensured and the total power losses are minimized (reduced levelized cost of energy). As a case study, the optimization framework has been implemented on the preliminary design of an offshore transmission system, in which some aspects of the design are predetermined and the optimization problem has only a few degrees of freedom. In spite of this, the design has been optimized such that reactive power provision and grid voltage comply with the grid code requirements, while the total power loss in the system has been minimized. The optimization framework is applicable on any other design with any other degrees of freedom. Optimizing the design of a combined wind farm collection grid and offshore transmission system can be conducted using the optimization framework discussed in this paper. Depending on the grid code requirements and the design stage, which affects the number of decision variables, the problem can be reformulated as a multiobjective or single objective optimization problem.
