Regulating turbine outputs to achieve a target voltage

An aggregated voltage controller for a cluster of fluid turbines, the aggregated voltage controller comprising:

• at least one processor configured to:
• receive a target voltage level for the cluster of fluid turbines;
• receive via a plurality of rectifiers, each rectifier associated with a different fluid turbine in the cluster of fluid turbines, an indication of a DC voltage associated with each fluid turbine, wherein the DC voltage associated with at least one of the fluid turbines in the cluster is below the target voltage level;
• and
• based on the received indications of the DC voltage signals associated with each fluid turbine in the cluster, output a control signal to each of a plurality of DC-DC converters associated with the plurality of rectifiers,
• wherein each control signal is configured to regulate each DC-DC converter to produce a DC output signal at the target voltage level such that combining each DC output signal in parallel produces an aggregated DC voltage conforming to the target voltage level.
