Abstract The increasing integration of renewable energies in the French electricity network leads to important changes in its operation, resulting in new grid constraints. Besides, some maintenance tasks on the overhead power lines are live-line works, and others require a planned outage. Such interruptions may not be feasible with a renewables-driven grid operation. As a consequence, current maintenance planning methods might not be relevant in the future. In particular, they have to take into account the risk implied by performing maintenance when having a high proportion of renewables in the grid. This work presents a three-step approach for tackling this issue. First, risk values corresponding to different future scenarios are computed, using the (N-1) security assessment. Second, these computed values are included in several optimisation approaches in order to find a good schedule. Eventually, a third step validates the obtained planning.

基于电网运行的停电维护规划

摘要 可再生能源在法国电网中的日益融合导致其运营发生重大变化,从而导致新的电网约束。此外,架空电力线路的一些维护任务是带电工作,而另一些则需要计划停电。对于可再生能源驱动的电网运行,这种中断可能是不可行的。因此,当前的维护计划方法在未来可能不再适用。特别是,当电网中可再生能源比例很高时,他们必须考虑执行维护所隐含的风险。这项工作提出了解决这个问题的三步法。首先,使用(N-1)安全评估计算对应于不同未来场景的风险值。第二,这些计算值包含在几种优化方法中,以便找到一个好的时间表。最终,第三步验证获得的规划。
