英文要約Title: Japan US Island Grid Project (FY2011-FY2015) FY2013 Annual Report (FY: Fiscal Year)

In FY2013, Hitachi conducted the following activities:
- Installation of system equipments with the cooperation of local volunteers,
- Operation checks and tunings for demonstration system,
- Penetration tests for the cyber system security, and so on.
Then the operation and data accumulation and analysis started from Dec. 17th
And engineering for the next step energy management system such as GCS (Grid Control System) is starting.

In this project, our system has an aim to utilize more and more RE (Renewable Energy) by using large number of EVs that will be implemented in coming future, and to stabilize fluctuation of nature power source of middle voltage and low voltage level by using battery systems and home load curtailment system.
In addition, the system has strong guard functions against cyber attacks.

This system consists of 4 main functional server groups and equipments as follows.

(i) EV Energy Control Center
(ii) Distributed Management System
(iii) Direct Load Control
(iv) Information & Communication Technology Platform.

(1) DC Fast Chargers (DCFC)
(2) Bulk Battery Systems (Lead Acid, Lithium-Ion, Static Var Compensator)
(3) Section Switches
(4) μ-DMS (micro Distribution Management System)
(5) Home Gateway with Load Control Switch for EV Normal Charger or Water Heater.
(6) Smart PCS (Power Conditioning System)
(7) Home Battery
(8) Smart Meter and Advanced Measurement Infrastructure
