Powercorp has developed a rapid energy source and sink system based on a modern flywheel and bi directional inverter. Energy required to prevent under frequency is drawn from the flywheel at a rate of 1MW in 5msec. Alternatively the system can absorb energy surges at the same rate and prevent driving grid conditions outside utility specifications.
A power and automation technology group, ABB, has agreed to acquire an Australian renewable power automation company, Powercorp. The acquisition improves control technologies ABB uses to combine renewable energy sources.
Darwin based Powercorp employs about 30 people and offers automation and intelligent controls to manage renewable-energy generation in isolated grids, ensuring utility grade power quality and grid stability. This enables higher levels of wind and solar power penetration into isolated diesel powered grids, thus reducing emissions and dependency on fossil fuel.
Powercorp has installed several systems to integrate renewable power into remote grids and keep generation in balance with consumption. The company also supplies systems that dynamically store and release energy in response to frequency and voltage deviations, to stabilize small or remote grids. The transaction is expected to close before year end.
