Abstract: The wind farm generators are new energies sources in the Algerian electrical networks, as every project their placements are determined by the wind assets of the site suitability (economic evaluation), its proximity to the power grid of which it will be connected (technical assessments). The other problem which is not taken into account or not studied in a satisfactory way is the electrical environments in witch the wind generators are to be subjected. So it is shown in this paper, that in the case of a power distribution under strongly nonlinear loads, the wind farm presents difficulties in maintaining an acceptable power quality, due to the measurement apparatus errors incompatible to this type of non linearity. Wind generator MPPT are controlled and regulated mainly by 3 loops, based on active power, reactive power (sometimes substituted to a power factor) and bus bare voltage measurements. So, in this paper it is shown that in nonlinear condition these parameters are faultily measured. Thus, new relevant definitions and formulation of active power and true power factor correction with other types of power are proved and detailed in order to improve the governor wind farm energy management.
