Problematika priključenja vetroelektrana na prenosnu mrežu EMS ad

in 2018 the first connections of wind farms to the transmission network EMS have been realized. In a short period of time, the total of four (4) wind farms were put into operation and, therefore, with engaging a lot of employees, it was necessary to modify and adapt a number of procedures and regulations in order to conclude all the Wind Energy Exploitation Agreements. Due to the stochasticity of the wind phenomenon, the forecast of wind farm production and its relation to the achieved energy production shall be addressed. As the employees of JSC EMS meet for the first time with this type of production capacities, the paper contains real data on meteorological parameters that influence the production of electricity from wind farms. Since all four (4) wind farms are located in the same geographical area, their impact on power flows, operational planning and balancing of the electrical power system shall be analyzed.
