Integrated Method for Optimizing Connection Layout and Cable Selection for an Internal Network of a Wind Farm
Main Article Content
Abstract
An internal network of a wind farm is similar to a wide network structure. Wind turbines are deployed over a vast area, and cable lines used to interconnect them may have lengths reaching tens of kilometres. The cost of constructing such a network is a major component of the entire investment. Therefore, it is advisable to develop a configuration of such a farm’s internal connections which will minimise the cost, while complying with technical requirements even at the design stage. So far this has usually been done within two independent processes. At first the network structure ensuring the shortest possible connections between the turbines is determined. Then appropriate cables compliant with technical regulations are selected for the specified structure. But does this design approach ensure the optimal (lowest) investment cost? This paper gives an answer to this question. A method for accomplishing the task given in the title is presented. Examples of calculations are presented and results are compared for the two methods of optimal wind farm internal connection structure design and cable cross-section dimensioning: two-stage and integrated. The usefulness of employing the Mixed Integer Nonlinear Programming (MNLP) method in the process of determining the optimal structure of a wind farm’s cable network is demonstrated.
