2011-11-24 - ABB is helping Hawaii maintain its reputation as a leader in renewable energy through the supply of its power converter system, developed in Napier.
ABB is working in conjunction with Saft, world leader in the design and manufacture of advanced technology batteries for industry, to support the "Hawaii Energy Storage System" project to increase the grids' ability to integrate more renewable energy.
Using federal stimulus funds, this project aims to accelerate the use of renewable energy in Hawaii, which is already a leader in this area with more than one-third of its energy coming from renewable sources.
ESS solution
The joint energy storage system solution combines Saft’s 2 Intensium Max 20E containers along with ABB’s PCS100 energy storage system (ESS) to create a turnkey solution comprising a Li-ion battery, power conditioning system, communications interface, as well as the installation and commissioning features. Main functions include various grid support services - for example the reduction of renewable output power volatility, as well as responsive charging and discharging, frequency regulation, autonomous operation and electrical output management.
ABB's PCS100 technology
ABB’s ESS power conversion system ranges from 100 kVA-10MVA and provides wide bandwidth performance with a flexible and highly modular power electronic configuration. ABB’s technology provides the opportunity to store energy from the electricity grid and return it when required. ABB PCS100 ESS offers advanced features and configuration options, such as should a grid supply be lost, the PCS100 ESS can detect this, disconnect itself from the grid and shut down. However, in some applications it is desirable to keep sections of load supplied so alternatively, the system can disconnect from the main grid but continue to supply local loads. When the grid returns, the systems will automatically re-synchronize and return to grid connect mode. | |
Deliveries of the solution will begin in April 2012.
