电力系统是最重要的基础设施之一，定期维护工作是输电系统运营商（TSO）非常重要的任务。部分停电的检修工作被称为“停电工作”，迄今为止，作者已经研究了一个高可靠性的大规模电网停电工作计划。然而，近年来，大量光伏（PV）和其他可再生能源（RES）被安装到电网中。此外，由于解除管制，TSO甚至难以掌握传统大型电源的运行模式，年度停电工作计划的规划任务也变得困难。因此，即使在不确定的情况下，也有必要考虑适当的供需条件，以便在停电工作期间获得可靠的电网配置。在本文中，作者研究了什么样的条件下，应该假设停电工作规划，并提出了一种推导方法，以获得适当的电网配置停电工作期间。通过数值仿真验证了该方法的有效性。
Electric power system is one of the most essential infrastructures and regular maintenance works are very crucial tasks for transmission system operators (TSO). Maintenance works with partial outage are referred to as “outage works” and the authors have so far studied a highly reliable outage work planning for large scale power grids. In recent years, however, a huge number of photovoltaic (PV) and other renewable energy sources (RES) are being installed into the power grids. In addition, it is getting difficult for TSOs to grasp operation patterns of even traditional large-scale power sources due to the deregulation, and the planning task of annual outage work program is also getting difficult. Therefore, it is necessary to consider appropriate supply-demand conditions for obtaining reliable grid configurations during outage works even in the uncertain circumstances. In this paper, the authors investigate what kind of conditions should be assumed for outage work planning and propose a deriving method to obtain appropriate grid configurations during outage works. The effectiveness of the proposed method is verified through several numerical simulations.
