Microproduction, also called distributed generation, is something that has become more and more popular in the electric grid. Microproduction can however lead to unacceptable performance if several units are installed in the same low voltage network. It is therefore good to know a limit where the performance of the low voltage network becomes unacceptable based on given parameters. This limit is usually called hosting capacity.In this report the hosting capacity with respect to voltage and current have been studied in three low voltage networks which are located in Falu Elnäts concession area. This has been done by simulations in a GIS-program where critical times of the grid have been simulated.

Mikroproduktion innebar att kunden sjalv kan producera och anvanda sin el. I Sverige finnsett okat intresse for att tillverka sin egen el och har under den senaste tiden okat markant.Denna uppsatsen har jag skrivit for att underlatta vid installation av vindkraft respektivesolceller, jag har aven gjort en ekonomisk analys av dessa for att fa en battre bild over detekonomiska av att producera egen el, darfor finner man nagra olika analys aspekter ochkostnadskalkyler i denna uppsats. Genom dessa analyser har jag kunnat dra nagra slutsatserbetraffande de bada och om ifall att det ar ett bra kop pa lang sikt. Det visar sig vara sa atten storre anlaggning ar en battre investering an en mindre da det ar installationen avanlaggningen som ar kostsam..
