| Outline of Final Research Achievements |
In this study, the adjustable speed generator (ASG) is proposed for diesel engine-driven power plants to stabilize the fluctuating power from the renewable energy source (the wind power is specified in this study) in a micro grid, and its performance is evaluated through simulation analyses by using natural wind conditions. In addition to the employment of the ASG in the diesel power plant, the battery energy storage system (BESS) and the wind power are also proposed to support the frequency control of the ASG.
In the results, the proposed ASG can regulate the fluctuating power of the micro grid efficaciously, and its control ability can be enhanced by adding the cooperative power regulation of the BESS and the wind power. Consequently, it can be concluded that wind power utilization in an isolated micro grid can be augmented by employing the proposed coordinating control system of the ASG based diesel engine-driven power plant and the cooperation of the wind power and the BESS.

| Academic Significance and Societal Importance of the Research Achievements |
我が国にも数多く存在する有人島のほとんどでは重油を燃料とするディーゼル発電でほぼ全ての電力がまかなわれており排ガス等の環境負荷が大きいため，マイクログリッド技術を活用した風力発電等の自然エネルギーを積極的に導入することは大いにメリットがある。本研究はマイクログリッド制御の一手法を提案し，風力発電などの変動電源が含まれていても主電源の高速な電力調整と風力発電との協調制御により変動抑制が可能であることを示した。また，本研究の成果は住宅用などの小規模なシステムへも応用可能であり，自然エネルギーを自宅に導入するような利用形態などを様々な条件で解析・提供することも可能としている。
