Abstract: A DC connection system for renewable power generators includes a first monopole DC collection network, a second monopole DC collection network and a first bipole transmission system. The first monopole DC collection network aggregates positive-valued DC voltage outputs of a first cluster of renewable power generators onto a positive terminal of the first monopole DC collection network. The second monopole DC collection network aggregates negative-valued DC voltage outputs of a second cluster of renewable power generators onto a negative terminal of the second monopole DC collection network. The first bipole transmission system is coupled to the positive and negative terminals of the monopole DC collection networks, for transferring the aggregated power to a power grid substation.

Abstract: Among other things, a distribution transformer and a technique for regulating voltage are provided for herein. The distribution transformer comprises at least three windings and at least two ferromagnetic cores. The distribution transformer may also comprise a power electronic AC-AC converter operable to maintain the input voltage and current of the distribution transformer substantially in phase and/or to reduce fluctuation in the output voltage of the distribution transformer in the event of an increase or decrease in the input voltage, for example.
