Higher targets for renewable energy and current trends in wind power and photovoltaics (PV) suggest that future power systems will include large amounts of renewable and variable power generation. Integration of large-scale variable power generation changes the balance and operation of power systems; including scheduling of conventional generation units; transmission and use of balancing power. In this paper the Swedish power system is studied with the energy system optimisation model MODEST in a number of scenarios involving different combinations of large-scale solar and wind power. The model includes a representation of the Swedish district-heating systems to determine the effects on combined heat and power (CHP) operation. It is found that when renewable power generation is added to the present system; utilisation of investments in CHP plants is reduced due to an increased electricity surplus that favours use of heat pumps for district heating. At high penetration levels of both solar and wind power; water is spilled from hydropower reserves.
