| Outline of Final Research Achievements |
This study applies the Hexagonal Modular Multilevel Converter (H-MMC), which is a new converter configuration for three-phase AC/AC conversion, to a Loop Power Controller (LPC) for power system stabilization and proposes its control method. Using the model for the power line with LPC, the control method is proposed and verified by theoretical analysis and experiment. Based on the verification of simulation results, it was confirmed that it works properly about the control of active and reactive power between the feeders of primary side and secondary side and power supply and charge of battery to keep capacitor voltage valance. In addition, the experimental system and program of the control are developed and it is verified that the control of H-MMC is able to work.

モジュラーマルチレベルコンバータ(MMC)構成によるループパワーコントローラ(LPC)の回路構成と制御方式を提案し，本方式について動作可能であることを確認した。本システムが系統に適用された場合，MMCの特長からシステム自体の小型・軽量化，出力の低歪み化による高調波低減が期待できる。一方，LPCは特に系統の末端の電圧変動や電力流通の融通化に期待されるシステムであり，LPCにより有効電力や無効電力を制御することができるため分散型電源が多く接続される系統に対しての柔軟な電力系統の運用に貢献できると考えられる。
