Integrating RES into the Romanian transport system

The interconnection of wind sources characterized by a significant variability of generated power and the continuous growth of installed power in wind farms raises a number of specific problems both to the utilities and to the power system operator. One of these issues is to ensure the safe operation of the power system when the reduction of the wind generated power occurs. The compensation of not generated power by these wind sources has to be done by other sources that must ensure the necessary power reserve. The paper deals with the access of the wind farms to the Romanian transport system, both from the legislative (policies, regulations, certificates, and incentives) and from the power quality point of view. The flicker study becomes necessary as the wind power penetration level increases quickly.
