Onshore Wind Farm - Reliability Centered Cable Routing

• Onshore wind farm design requires various stages to be completed. Due to complexity, these stages can not be unified as one planning process. Rather, every design step is considered separately. The prime focus of this work is to assist planners and experts in finding the optimal cable layout of the onshore wind farm. The optimization algorithm is designed using a mixed integer linear programming (MILP). The MILP algorithm takes into account system relia- bility, power transfer capacities and power quality issue. Beside minimizing cable installation cost, the novelty in this optimization algorithm is to mini- mize the cost of lost energy production and therefore maximize the reliability of the system. Additionally, the algorithm supports the optimal selection among different cable options, with different features, prices and capacities. By calcu- lating voltage increase at the point of connection (POC), power quality issue is considered as well. The designed algorithm provides optimal results for four different wind farm layouts. Every layout is tested for three different case sce- narios, where different number and type of cables are considered. The results show that more cable options contribute in lowering the total costs. Moreover, cables with higher capacity can help in improving the power quality issue.
