Abstract: Wind farm comprising a farm master (1) and a plurality of wind energy installations (4). The farm master (1) has a controller (15) with an input for a control parameter for power supplied to a grid and transmits desired value specifications to a local controller (5) of the wind energy installations (4). According to the invention, the local controller (5) has a dual structure and comprises a desired value channel (6), to which the desired value specification is applied by the farm master (1) and which is designed to output a stationary reactive power desired value, and a responsive channel (7) comprising an autonomous controller (75), to which no desired value specification is applied by the farm master (1) and to which an actual voltage of the particular wind energy installation (4) is applied via a washout filter (71). The autonomous controller (75) with the washout filter (71) enables a fast and dependent response to transient disturbances, in particular voltage spikes and voltage dips as a result of a short circuit. The individual wind energy installation and the wind farm as a whole therefore gain a behaviour which is identical to a synchronous generator and is very favourable for grid stability in the event of voltage disturbances.

Abstract: Bacteria are genetically engineered to produce 3-hyrdoxypropionate (3-HP). The bacteria are carboxydotrophic acetogens. The bacteria produce acetyl-coA using the Wood-Ljungdahl pathway for fixing CO/C0?2#191. A malonyl-coA reductase from a bacterium that contains such an enzyme is introduced. Additionally, an acetyl-coA carboxylase may also be introduced The production of 3-HP can be improved by overproduction of acetyl-CoA carboxylase or by overproduction of biotin. This can be effected by improved promoters or higher copy number or enzymes that are catalytically more efficient.
