Due to the uncertainty existing over DC technology for WPPs,
some parameters such as the efficiency of DC/DC converters or DC
protections, are not well defined. Thus, the energy losses previously
introduced in equation (1) results of only the cable losses consideration.
Thereby, the total steady-state energy losses including the
power losses of power electronic elements (AC/DC and DC/DC
converters, and DC breakers) are evaluated by means of a sensitivity
analysis.
From the technical analysis, the breakdown of the losses is obtained.
This breakdown allows to determine the effect of each
element into the total power losses, distinguishing among the
different existing losses.
