要約(英語): Electric power system is one of the most important infrastructures and regular maintenance works (inspection, repair, replacement and so on) are very important tasks for transmission system operators (TSO). The maintenance work with partial outage is referred to as outage work” and the authors have so far studied a highly reliable outage work planning system for large scale power grids. In these days, however, a huge number of photovoltaic (PV) generation systems are being installed into the power grids. PV outputs are strongly affected by weather conditions and very difficult to be anticipated in advance. In addition, it is getting difficult for TSOs to grasp operation patterns of even traditional large-scale power sources due to the deregulation in the electricity industry. The planning task of annual outage work program is also getting difficult. The authors, therefore, believe that it is necessary to consider suitable 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.
