Abstract
In the SE4 bidding area in Sweden, there exist few sources of dispatchable power. The area relies on transmission from the north or intermittent production. The installation of a gas turbine could alleviate these issues in the near future and improve voltage stability and power transfer to the region. Depending on where this gas turbine is located, there will be differences in system performance. In this work, a model of the 400 kV transmission network with 50 nodes in the Nordic
region was used as a basis for simulations. For each location available to the 100 MW gas turbine, performance was evaluated with the increase of power flow to Sege, a crucial node in the SE4 subsystem. Various configurations of both the loads in SE4 and the... (More)
In the SE4 bidding area in Sweden, there exist few sources of dispatchable power. The area relies on transmission from the north or intermittent production. The installation of a gas turbine could alleviate these issues in the near future and improve voltage stability and power transfer to the region. Depending on where this gas turbine is located, there will be differences in system performance. In this work, a model of the 400 kV transmission network with 50 nodes in the Nordic
region was used as a basis for simulations. For each location available to the 100 MW gas turbine, performance was evaluated with the increase of power flow to Sege, a crucial node in the SE4 subsystem. Various configurations of both the loads in SE4 and the generation of the gas turbine were included, to determine the value of active and reactive power to the system. The results show that performance is the greatest when the gas turbine is placed in the nearest bus, but adjacent buses perform similarly. When power transfer to SE4 is considered, the result depends on which
transmission line is under the greatest load. Reactive power outperformed active power in terms of voltage stability when generated in an equal magnitude. To further improve upon these results, the load data in the model should be reconfigured to allow for different scenarios. To expand on this work, the methodology should also be applied to the SE3 bidding area. (Less)
Popular Abstract (Swedish)
Södra Sverige saknar planerbara energikällor. En gasturbin är en flexibel lösning på detta problem, men dess effekt kommer att variera beroende på var den placeras i det sydligaste elområdet SE4.
