This paper presents the world's first high voltage utility‐scale battery energy storage system in the multi megawatt range.
The objectives are achieved by the series connection of switching semiconductor devices of the type Insulated Gate Bipolar Transistor (IGBT) and the series and parallel connection of Li‐ion batteries.
After tests at ABB laboratories, where its performance to specification was confirmed, a first pilot will be installed in the field, in EDF Energy Networks' distribution network in the United Kingdom during 2010 to demonstrate its capability under a variety of network conditions, including operation with nearby wind generation.
This holds the development of a distributed dc breaker, the diagnostics of detecting fault locations as well as fault isolation and the balancing of the batteries.
The paper presents the world's first high voltage utility‐scale battery energy storage system in the multi megawatt range suitable for a number of applications in today's and future transmission and distribution systems.
