Outline of Final Research Achievements

This research aims to develop innovative power electronics and power system technologies that overcome the power system stability issues and realize the large penetration of renewable energy for stable power supply and countermeasures against natural disasters. The researchers have developed novel single-phase synchronization inverter (SSI) that generates virtual synchronization power which is equivalent to a three-phase synchronous machine. The researchers have also verified the basic operation modes of a single-phase microgrid (SMG) using the SSIs through simulations and experiments. The researchers also expanded inverter control functions, such as overcurrent protection, and built a prototype prosumer unit consisting of storage batteries, photovoltaic, and standard home loads. Furthermore, the experimental studies are conducted on the prosumer unit to demonstrate the SMG that was originally planned.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発した単相同期化力インバータは,単相配電線を多数の小区間に分離し各々独立に,あるいは自由に相互接続して利用できるので,災害時の電力供給の切り札となり得る。また,原理的に複数構成で三相回路を構成できる単相マイクログリッドは,人口減少が進む我が国において,山間部の限界集落などへの電力インフラ整備に対して,長距離配電線を用いる現在の方式に代わる安価で有効な代替技術ともなり得る。さらに,このような多数の独立した単相マイクログリッドの結合や拡張,切り離し,三相システムへの拡張や基幹システムへの接続が自由にできる特長は,海外の未電化地域の有効な電力供給手段となり,社会的意義が大きい。
