Claims (14)

1. Anordning omfattende et kraftværk (10), mindst et termisk energilager (T1, T2, T3) og mindst en energiomdannelsesindretning (20, 40), der er udformet til at oplade det mindst ene termiske energilager (T1, T2, T3) i et tidsinterval for et strømoverudbud, kendetegnet ved, at et første (T1) af det mindst ene termiske energilager (T1, T2, T3) er koblet termisk til en kondensator (15) af kraftværket (10).
2. Anordning ifølge krav 1 med en reguleringsindretning til strømtilvejebrin-gelsen til et strømnet, hvor reguleringsindretningen er udformet til at reducere strømudbuddet af kraftværket (10) ved opladning af det termiske energilager (T1, T2, T3) til det i dette tidsinterval foreliggende strømbehov, således at strømtilvejebringelsen i kraft af vedvarende energi til strømnettet har forrang.
3. Anordning ifølge krav 1 eller 2, hvor kraftværket (10) er udformet til konstant fuldbelastningsdrift.
4. Anordning ifølge et af kravene 1 til 3, hvor mindst et af det mindst ene termiske energilager er et varmelager (T1, T2), og en energiomdannelsesindretning er en varmepumpe (20), og hvor anordningen er udformet til at aflade varmelageret (T1, T2) via et fjernvarmenet (30).
5. Anordning ifølge et af kravene 1 til 3, hvor mindst et af det mindst ene termiske energilager er et kuldelager (T, T3), og en energiomdannelsesindretning er en kuldemaskine (40), og hvor anordningen er udformet til at aflade kuldelageret (T, T3) via et fjernkuldenet (50).

10. Fremgangsmåde til regulerbar strømtilvejebringelse via et kraftværk (10), hvor mindst et termisk lager (T1), der er koblet termisk til en kondensator (15) af kraftværket (10), oplades ved hjælp af en energiomdannelsesindretning (20, 40) i et tidsinterval af et strømoverudbud, og strømudbuddet til et strømnet af kraftværket (10) reduceres ved opladning af det mindst ene termiske lager (T1, T2, T3) til strømbehovet, der foreligger i dette tidsinterval, således at strømtilvejebringelsen i kraft af vedvarende energi til strømnettet har forrang.
11. Fremgangsmåde ifølge krav 10, hvor kraftværket (10) kører i konstant fuldbelastningsdrift.
12. Fremgangsmåde ifølge et af kravene 10 eller 11, hvor der som termisk energilager (T1, T2) anvendes et varmelager, der aflades via et fjernvarmenet (30), især i et tidsinterval, hvor der ikke foreligger noget strømoverudbud fra kraftværket (10).
13. Fremgangsmåde ifølge et af kravene 10 eller 11, hvor der som termisk energilager (T, T3) anvendes et kuldelager, der aflades via et fjernkuldenet (50), især i et tidsinterval, hvor der ikke foreligger noget strømoverudbud fra kraftværket (10).
14. Fremgangsmåde ifølge et af de foregående krav 10 til 13, hvor mindst et varmelager (T1, T2) oplades ved hjælp af en varmepumpe (20) og mindst et kuldelager (T, T3) ved hjælp af en kuldemaskine (40).
