内容
本プロジェクトは、系統安定化用蓄電池システムの劣化診断基盤技術を開発することにより、系統用蓄電池の寿命診断や評価を可能とし、蓄電池による安定供給を前提とした太陽光発電や風力発電などの次世代自然エネルギー機器の大量導入に貢献することを目的とする。主に系統安定化用の「大型蓄電池に対応した劣化診断技術及び劣化診断システム」と住宅太陽光・負荷実測データからの「電力変動プロファイル生成システムの構築」の二つを大きな柱とし、「系統連系円滑化蓄電システム」を模したLIB蓄電池システムを用いて劣化診断評価システムの検証を行う。
英文要約Title: Development of Safety and Cost Competitive Energy Storage System for Renewable Energy / Diagnosis Technology Development of Energy Storage System for Grid Stabilization (FY2011-2012) FY2011 Annual Report
This project aims to develop diagnosis technology of energy storage system for grid stabilization, and to contribute to introductions of the next generation natural energy equipment of the photovoltaic generation and wind power generation with energy storage system by the development of the diagnosis technology. In this project, "diagnosis technology development of large scale energy storage system" and "development of generation system for electric power change profile" were investigated for development of energy storage system for grid stabilization.
We investigated the measurement condition that can be the transition response analysis by the isolation pulse wave and frequency response analysis for diagnosis technology to a large-scale storage battery. In addition, relationship between results of transition response analysis and frequency response analysis was also investigated. Moreover, experimental apparatus for diagnosis technology of large scale energy storage system was developed partly. Using this system, the transition response by the isolation pulse wave from charge-discharge signal could be obtained.
We carried out the interpolation of missing data based on the measured residential-load data in the demonstrative research on clustered PV systems by NEDO. Next, In order to aggregate photo-voltaic (PV) data on various conditions, we first constructed a database system with MySQL. We then investigated interpolation methods for missing data based on spatio-temporal relations of PV data. Furthermore, validity of power flow condition for a small scale distribution network model with residential load and PVs was verified by power flow calculation.
