The ability to deliver distributed generation to support the grid is rapidly improving as the demand increases.
There is an example of GE delivering 104 MW of distributed generation in a matter of weeks. The generation package comprised four (4) gas turbines, of which two were delivered in 45 days.
The reduced delivery time was achieved using:
The distributed generation, if modular, has the possibility of being re-deployed to another site if the needs change.
The distributed generation may be embedded at the substation level or located at the end user level.
The distributed generation units may be traditional, thermal generators or renewable generators such as wind and solar, or hybrids.
The distributed generation can be used to support specific areas of the grid and to increase the grid security.
In order to deploy the distributed generation, the proper integration of the generation with the grid requires some analysis and design. For example, the distributed generation may need to be dispatched and monitored remotely. This may require integration of the generation control system into a SCADA. The extra generation may increase fault levels at the site, which could impact protection systems. The point of connection for the power circuits, the fuel system, earthing and lightning protection are other areas of consideration.
BESST are able to design the power and control systems for distributed generation, and integrate the generation into the existing power and control systems of the user.
