samverkan mellan vindkraft och vattenkraft med olika ägare

By Anna Jäderström


bad format, retyped Both wind power and hydro power must be built in immediate proximity to the source. Almost all hydro power is concentrated in the north of Sweden, since the largest rivers can be found here. The northern parts of Sweden also have good wind conditions and are therefore interesting for wind power projects. The transmission system in such areas may not have the sufficient capacity for additional power production, which calls for some kind of coordinated regulation between the hydro power producer and the wind power producer, in order to not produce more than can be transferred. A strategy for how to coordinate both power productions will avoid an expensive reinforcement of the net. In this thesis different strategies for coordinated regulation are studied and simulated using a linear programming model (LP). The major planning objective is to keep production goals and physically constraints of the power system. A model including objective function and constraints are presented for each strategy. Computational results are reported showing that both sides benefit from the coordination strategies and a better utilization of the transmission net.
