英文要約Title:R&D of Practical and integrated Energy storage systems for smart community/Elemental technology development/Demonstration project on Next-generation Energy and Social Systems in Japan
This project belongs to Demonstration project on Next-generation Energy and Social Systems in Japan by Ministry of Economy, Trade and Industrial (METI). The technological development is hybrid battery energy storage system by plural type of batteries and energy management for the practical demand application as office buildings and smaller stores. It also effects for mitigation of unstable power line problems by mass quantities and large Photovoltaic power generation systems. Hereafter, Described results of a period from April/2010 to March/2011.Hybrid battery energy storage system to suitable for office buildings and smaller stores:The prototype for fundamental functions evaluation has been designed and several batteries were ordered. It has been constructed by following parts.1) AC/DC converter Part: It is power conditioner to connect power supply line and Common DC-Bus line.2) DC/DC converter Part: It is voltage & energy adjuster for Plural type of batteries and Photovoltaic to connect common DC-Bus line.3) Plural type of Batteries Part: These have battery management and communication functions to protect and controlled energy by DC/DC converters.4) Photovoltaic (PV) Part: It connects to Common DC-Bus thru the DC/DC converter as batteries.5) Quick charger (QC) Part: It connects to Common DC-Bus line. It is specific modification of standard QC.A prototype BEMS: Building energy management system for the smart battery system 1) had been designed. It realizes coordination and cooperation of energy control with the smart battery and facilities in the building such as generators, photovoltaic generators, HVAC systems, lighting systems, elevators and water pumps. It also can adjust the schedule of charging electrical vehicles in viewpoint of total building energy management and control. It can manage and control load dispatching of each battery considering priority of usage and constraint conditions.Prototype smart load equipment 2) is developed that is a DC current type LED lighting system for building.1) Smart battery system: It is the concept of battery group management system with plural batteries of different types and/or new and used butteries.2) Smart load equipment: It is the concept of electric equipment that has the function of battery conscious properties such as DC current acceptability function, protection relay for over-current, etc.As to the storage battery system for the electricity demand and supply adjustment, the system configuration including a battery, a power conditioner system (PCS), and auxiliary devices was investigated. The cooling method was carefully studied since the amount of the heat generated in a very quick charging and discharging can be large. The battery panel design in the system aims to be compact and efficient in cooling so that it can be installed in a shipping container. Besides, the simulation architecture of the supply-and-demand situation on the community-wide electric distribution network was investigated to find the suitable battery specifications for the community, and a model of battery, one of the simulation objects, was designed and verified.
