| Outline of Final Research Achievements |
In future electric power systems including a lot of PVs and wind power generators, the ability of frequency control for balancing supply and demand deteriorates because of the decrease of generators being able to control their outputs. Therefore, load control becomes important to compensate for the ability of frequency control. The purpose of my study is to clarify the effectiveness of the application of a dynamic quantizer to autonomous decentralized load control for enhancing compensation. The results of simulation studies showed that the dynamic quantizer is effective to enhance the ability of frequency control, but it creates a new challenge. In addition, the potential electrical appliances available for load control were investigated with a questionnaire.

| Academic Significance and Societal Importance of the Research Achievements |
電力システムにおける負荷制御は、需要家所有の空調機などの電気機器を対象に、その消費電力を離散的に変更する。そのため、消費電力の変更の仕方によっては電力システムに対するじょう乱となり、逆効果となる。この逆効果を発生させず、周波数変動の抑制効果を向上させ得る方法として、動的量子化器の制御理論の応用可能性を示した点が本研究成果の学術的意義である。また需要家を対象としたアンケート調査により負荷制御に利用可能な電気機器の潜在量を推定した点は、今後の電力システムの安定運用に役立ち、社会的意義がある。
