Strategi för utvecklande av reglerbudata
This Master Thesis discusses the development of bids for regulation power with consideration of change of discharge. The study was initiated by Vattenfall PD and is a limited part of a substantial development project at the same division. The background of the project is the new demands from SvK, which among other things includes more detailed regulation bids. As from the 1st of November 2008, the regulation bids are supposed to be calculated regarding each specific regulation object, something that is defined by SvK. These new demands changes Vattenfall?s conditions and will increase the need for detailed knowledge about available regulation power and costs for regulation.In this study a strategy for regulation bids was developed. Proper quantities for bids have been defined and costs for regulation power have been calculated. The pricebids are calculated with regard to change of efficiency as a function of the discharge and the water value. The strategy has been developed with consideration to hydrological couplings, physical and technical parameters and market constrains. In order to provide background information for the reader, the first chapters of the report describes the Nordic power market, production planning of hydropower plants and regulation power.A case study has been performed with the purpose to understand how the new demands and the strategy developed in this report might influence the regulation bids. The results from the study indicates the developed strategy increases the quantity of regulation power thought the market and will lead to more competitive bids since they will be more detailed and have more advantageous pricebids.
