An Autonomous DC Microgrid System Inspired by Electric Vehicle Technologies

電動車両技術を参考にした自律型DC マイクログリッドシステム

This paper introduces an innovative electric power distribution system for residences that is inspired by power management systems for electric vehicles. To counteract the negative impacts of climate change on a global scale we need to build a sustainable society that can accelerate the transition from fossil fuels to renewable energy sources such as wind or solar. However, renewable energy sources such as wind power or solar power are intermittent and difficult to predict. Thus, it is difficult to maintain the balance between energy supply and demand on energy systems and it makes electricity distribution a challenging topic. On the other hand, in recent years many global auto companies are releasing EV, PHV or FCV into the market. We could take advantage of this evolution as a potential solution for the previously mentioned demand-response issues that arises when using renewables. In this paper the authors study an autonomous DC microgrid system concept based on renewable energies that uses electric vehicle technologies such as bidirectional DCDC converters with intermittent operation. They built real-time simulations of the microgrid system that show a renewable energy replacement ratio of up to 85% under proposed system conditions.近年,EVやPHEVが市販され,FCEVのV2H実証実験が行われる等,電動車両と電力システムが結びつき,また災害対策や再生可能エネルギー利用拡大のため,電力需給調整システムとして電動車両を利用することが検討されている.この論文では電動車両技術を参考にした一般家庭向け自律型DCマイクログリッド電力システムをリアルタイムシミュレーションにより検討し,その可能性について報告した.
