Claim 0:
1. A method for transfer of power between medium voltage, MV, feeders via a MV direct current, MVDC, link in a power distribution network, the method being performed in a controller in the power distribution network and comprising:
setting an iteration step value for each of a set of power reference quantities of the MVDC link, and setting an initial value for each of the set of power reference quantities;
iteratively changing values of each of the set of power reference quantities, and selecting one changed value of the set of power reference quantities by:
changing a present value of each of the set of power reference quantities, one at a time, with the set iteration step value, respectively, into a new value, and measuring a total active power at a substation of the power distribution network for each of the new values, one at a time; and
selecting the new value of one of the set of power reference quantities that provides a lowest measured total active power at the substation, wherein a next iteration is performed with the selected new value as present value for the one of the set of power reference quantities and with the present value for all other of the set of power reference quantities.
