英文要約Title: Japan US Island Grid Project (FY2011-FY2014) FY2011 Annual Report (FY: Fiscal Year)

In FY2011, Hitachi did basic design and part of detail design for demonstration system.

The system shall be considered the counter measures for frequency fluctuation mainly originated by wind power down ramp event, and impacts by large amount of EV charging load will be implemented.
In this system design phase, Hitachi utilizes following 4 main technologies: (i) The Integrated distribution system management: (ii) Demand side direct load control: (iii) EV SOC monitoring and remote charging management (iv) Information & Communication technologies.

(1)(2)(3) shows the main demonstration themes for the system.
The name of the major subsystems Hitachi did design work are
listed in (1)(2)(3).
(4) shows the evaluation themes Hitachi did preparation work for
the demonstration system.

(1) An advanced island smart grid demonstration with EV in Maui
- EV energy control center (EVECC)
- Bulk Battery Systems
(2) Smart Grid Demonstration at substation level in Kihei
- Distribution Management System with EMS plus and Direct Load Control functions.
-μ-DMS (micro Distribution Management system)
(3) Smart Grid Demonstration at low voltage line level (a pole trans or a pad mount trans level).
- Home Gateway with Remote Circuit Breaker, EV Normal Charger
- Smart PCS (Power conditioning System)
- Smart Meter and Advanced Measurement Infrastructure

(4) Preparation work for Overall reports as the result of the demonstration project
- Collaboration work with DOE project in Wailea.
- Evaluation for the result of Cyber security assessment
- Evaluation for the system in the demonstration project from economic viewpoints
- Simulation and study of the business models which shall be the best solution for Island Smart Grid and Low carbon society.
