| Outline of Final Research Achievements |
Solar power generation or variable-speed wind power generation are connected to the grid through a converter using power electronics technology. Conventional power systems are supplied with power from synchronous generators. Therefore, the inertial energy and synchronizing power of the synchronous generators contribute to stabilizing the power system. As renewable energy becomes more introduce and renewable energy generation increases in the power system, the number of synchronous generators decreases, raising concerns about power system stability. Research and development is being conducted on the introduction of virtual synchronous generator control, which virtually simulates a synchronous generator in the converter of renewable energy generation. In this study, we propose gain scheduling control that follows a virtual synchronous generator model.

系統追従方式の仮想同期発電機制御を瞬時値最適制御であるゲインスケジューリング制御が適用可能であれば、仮想同期発電機制御のロバスト性や追従性能の向上が期待でき、過電流抑制の向上が期待できる。これらは、系統への導入時にコストダウンしつつ、信頼性向上が期待できる。制御工学としては、極が単位円に近い仮想同期発電機モデルのような目標へゲインスケジューリング制御の導入ができれば、この制御手法の適用範囲の拡大が期待できる。
