The The MultiMulti--area Power Market Simulatorarea Power Market Simulator ((EMPSEMPS))

A process-oriented model

Different elements of the electrical power system modelled with their capacities and costs

Optimal long-term utilization of total resources is sought subject to:future inflow (stochastic)thermal-based generationdemand (temperature dependent)spot-type market options

Probably the most used energy market model in the Nordic countries

Market price forecastingStudies of the electrical power market and power systemExpansion planning (major plants, international links)Generation scheduling
