Estimation of the Feasible Wind Power in a Small Power System
AbstractDue to wind variability and difficult forecasting, the maintenance of the balance between generation and demand of the electric power systems is complicated, especially in small power systems with large generating units. This article analyses evaluation of the feasible wind power in small system without investment. Feasible wind power is limited by primary reserve. During critical operation conditions, majority of units operates at lowest permissible value, thus decreasing wind power share in power system balance. Asynchronous links can significantly change available regulating power reserve. The regulating power reserves, feasible wind power of the Lithuanian power system and algorithms for regulating power reserves evaluation were set in this article.
