Abstract [en]

A satisfying analysis of the impacts of introducing significant shares of wind power in a electricity system requires that the stochastic nature of wind power production is taken into account. An hour-per-hour stochastic, optimisation model of the electricity systems in Denmark, Finland, Germany, Norway and Sweden has therefore been developed in the WILMAR project. To our knowledge it is the first model of this type to be developed for a large electricity system. Treatment of large hydropower reservoirs requires optimisation of the use of water over a yearly or longer time horizon. Therefore the hourly, stochastic optimisation model is combined with another stochastic, optimisation model focusing on calculating the option value of stored water dependent on the time of year and reservoir filling. Finally a third set of models have been developed that make regional wind power production forecasts, and reduces these forecasts into a scenario tree used by the hourly, stochastic optimisation model. These models are combined with databases into a Planning tool enabling analysis of liberalised, electricity systems with large shares of hydropower production and fluctuation power production. Considerations about how to represent a liberalised, electricity system in the hourly, stochastic optimisation model ended up in the modelled electricity system consisting of three markets: a day-ahead market, a balancing hour-ahead market, and finally a market for daily reservation of primary reserves. By dividing the geographical area into regions connected with transmission lines the Planning Tool can investigate the effect of bottlenecks and investments in transmission capacity.
