電気自動車(EV)やプラグインハイブリッド車(PHV)には大容量の蓄電池が搭載されています.駐車中は次の走行に向けて充電をしますが,逆に電力に余裕があるときは放電して建物内の家電機器の電力消費に当てることができます.賢く車載蓄電池の充電と放電(充放電)を制御することにより,建物のエネルギー(電力)を賢く制御することができます.エネルギー管理システム(Energy management system: EMS)にとって,EVやPHVは有望なエネルギーバッファとなるのです.
稲垣研究室では,「1. 観測」「2. 予測」「3. 計画」を繰り返して車載蓄電池の充放電を制御する,モデル予測型EMSを研究しています.
Electric vehicles (EVs) and plug-in hybrid vehicles (PHVs) are equipped with large-capacity storage batteries. While parked, the batteries are recharged for the next run, but when there is a surplus of power, the batteries can be discharged to be used for power consumption by home appliances in the building. Smartly controlling the charging and discharging of on-board storage batteries enables the building's electric power to be efficiently controlled. EVs and PHVs are promising energy buffers for energy management systems (EMS).
Inagaki Laboratory is studying a model predictive EMS that controls the charge and discharge of on-board storage batteries through a series of "1. observation," "2. prediction," and "3. planning.
EVやPHVは移動する大型蓄電池とも言えます.街を移動するEVやPHVの車載蓄電池を統合的に管理して,地域全体のエネルギー管理を行う研究も進めています.車載蓄電池を統合的に管理するには,建物のEMS間で協調して充放電を制御する必要があります.本研究では,EMS間の協調を含めたモデル予測型EMSを開発すると共に,またEV・PHVと建物との間でやりとりされる電力の電気代の自動算出方法も開発しています.
EVs and PHVs can be regarded as large mobile storage batteries. We are also conducting research on integrated management of vehicle-mounted storage batteries for EVs and PHVs that move around the community to manage the energy of the entire region. Integrated management of vehicle-mounted storage batteries requires coordinated control of recharge and discharge among building EMSs. In this research, we are developing a model predictive EMS that includes coordination between EMSs, as well as a method for automatically calculating the electricity bill for power exchanged between EVs and PHVs and the building.
