针对海上风电场的优化配置问题，提出了一种新颖的方法。多亏了成本模型，我们考虑了电网所有部分的成本。基于遗传算法的优化平台还允许我们评估OWF的可靠性。这种方法被用来比较在不同情况下在真实的OWF“Banc de Guerande”上获得的拓扑。将选择的OWF设计与使用不同方法获得的结果进行比较：成本优化，或同时进行成本和可靠性优化。优化结果表明，如果考虑总成本，包括在OWF寿命期间未提供的预期能量，环拓扑结构会给出有趣的结果。在优化中还考虑了近海变电站的数量和位置：我们证明了以合理的成本引进更多的变电站以获得更好的性能是可能的。提出的优化工具可以帮助设计这样的农场，并考虑到几个约束。
This paper presents an original approach aiming to obtain the optimum configuration of an offshore wind farm (OWF). Thanks to cost models, we take into account the costs off all the parts of the electrical network. The optimization platform, based on a genetic algorithm, also allows us to evaluate the reliability of an OWF. This approach is used to compare the topologies obtained in different cases on a real OWF, the “Banc de Guerande.” The selected design of the OWF is compared to the results obtained using different methods: cost optimization, or both cost and reliability optimization. The optimization results show that the ring topologies give interesting results if the total cost including the expected energy not supplied during the lifetime of the OWF are taken into account. The number of offshore substations and their positions are also considered in the optimization: we show that the introduction of more substations in order to obtain better performances is possible at a reasonable cost. The presented optimization tool can help to design such farms taking into account several constraints.
