Challenges of integrating wind power plants into the electric power system: Lithuanian case

This article reviews the technical problems which must be solved to support the development of wind energy in Lithuania. Two technical objectives were identified: determining the power transmission capacity of the electricity network, and balancing the energy generated by wind power plants related to the error control of forecasting. To complete these objectives, it was necessary to review the historical development of wind energy in Lithuania and the recent (2016) situation in accordance with statistical data. The forecast errors of the system load and generation by wind power plants, and demands of balancing and control reserves were established. The potential for connecting wind power plants to the Lithuanian power transmission network were then analysed. This article also discusses the wind energy development possibilities in Lithuania.
