Kansai Electric Power Co., Inc. (hereinafter, “Kansai Electric Power”), Erie Power Co., LTD. (hereinafter, “Erie Power”) and SANSHA ELECTRIC Mfg. Co., LTD. (hereinafter, “SANSHA ELECTRIC”) are all in January 2019. From the 7th to the 31st of January, we conducted a demonstration test in which household storage batteries and industrial storage batteries owned by consumers were used as energy resources and immediately charged and discharged according to short-cycle load fluctuations in the power system.
This demonstration test is the first initiative in Japan to verify a technology that can remotely and collectively control the charging and discharging of approximately 10,000 storage batteries in seconds. (Notified on December 17, 2018)
In this verification test, the storage battery group monitoring and control system “K-LIBRA” built by Kansai Electric Power Co., LTD. With NEC Corporation (NEC) to collectively control the storage batteries, and Erie as a storage battery that can be remotely charged and discharged in seconds. By linking the household storage battery developed by Power and the industrial storage battery developed by NEC, we verified the response performance of the storage battery to the command from the system.
As a result of the verification, about 2 seconds after “K-LIBRA” simulated the output control command from the central Power Supply command center, the control command was sent to the actual storage battery (2 units) and the simulated storage battery (9998 units). I confirmed that I can send. We also confirmed that the actual household storage battery and industrial storage battery can respond to load fluctuations with a short cycle of about 10,000 units, so we will confirm the technology for controlling about 10,000 storage batteries in seconds. I was able to.
This is the first virtual power plant in Japan to demonstrate that it can collectively control the storage batteries owned by consumers on a scale of about 10,000 units and control them in seconds like a generator.
Kansai Electric Power, Erie Power and Sansha Denki will continue to aim to establish technology for practical use.
For this verification test, Kansai Electric Power Co., Inc. Applied for the “2018 Virtual Power Plant * 1 Construction Demonstration Project Cost Subsidy Utilizing Consumer Energy Resources”, which is a subsidy of the Agency for Natural Resources and Energy. It was implemented in response to a grant decision on May 29, 2018 from the Environmental Co-creation Initiative, an executive organization.
* 1 By converting the customer’s machinery scattered in the power system to IoT and collectively controlling it, it can be delivered from the customer’s machinery.
A mechanism that makes effective use of the supply and demand adjustment capacity that can be achieved and makes it function as if it were a single power plant (virtual power plant).
