実系統に基づく大口需要家自家用発電設備モデルの過渡安定性に関するシミュレーション

In recent years, non-utility generators of large consumers have been expected to contribute to the stabilization and restoration of power supply during in the event of a disasters. For this purpose, it is required to maintain the interconnection with the utility power system for a while during emergencies. However, if the non-utility generators are not able to maintain stable operation due to grid disturbance, not only the operation of the consumers will be suspended, but also the operation of the utility power system will be disturbed. In this paper, we construct a grid analysis model based on a real power system that includes a large consumer with non-utility generators, and show the issues that may arise in the generators through simulation.
