In contrast to multi-megawatt systems, small wind turbines are used mainly as battery chargers for stand-alone power supplies. As heating mills for the support of heating systems, and as wind pumps for water supply systems. In the past few years another trend has emerged: The use of small, grid-connected, wind turbines whose generated energy is supplied directly into existing public grids or stand-alone grids.
In more detail:
Together with batteries, the Blue Hybrid creates an AC grid in which power generators, as well as energy loads, can be connected, depending on the requirements. In doing so, the Blue Hybrid performs all control processes, such as the management of the grid’s voltage and frequency. In addition, it channels surplus energy directly to the batteries to store it there. Conversely, it supplies the AC grid with the energy stored in the batteries in the event of any shortage caused by consumption exceeding production.
