Mikroproduktion med solceller: Användandet av acceptansgränser

Abstract [sv]

Detta arbete har med hjälp av acceptansgränser uppskattat hur mycket mikroproduktion som kan installeras i ett lågspänningsnät och resultatet presenteras som en karta över ett referensområde. Arbetet visar att det trots ett mycket starkt elnät i huvudsak är acceptansgränsen för spänningshöjning som kommer att vara begränsande. Det läggs fram tre förslag på åtgärder som underlättar införandet mikroproduktion. Mätning för att uppskatta återstående marginal till acceptansgränsen, vilket sedan kan fungera som ett beslutsunderlag för att tillåta mer installerbar effekt. Justering av transformatorns nominella spänning, vilket frigör utrymme för mer produktion. Möjligheten till begränsning av produktion under kritiska timmar medför att mer installerbar effekt kan tillåtas och det finns mer tid för genomtänkta investeringar.

Abstract [en]

This work has estimated the amount of microgeneration that may be installed in a low voltage grid based on hosting capacity limits and presents an overview of a reference area. The work shows that despite a very strong power grid, it is essentially the hosting capacity for voltage increase that will limit microgeneration production. Three proposals are given for measures that facilitate the introduction of microgeneration. Measurements to estimate the remaining margin to the hosting capacity limit, which serves as a decision base to allow more installable effect. Adjustment of the transformer's rated voltage, which increases the hosting capacity and allows more production. Production curtailment during critical hours means that more installable power can be allowed and there is more time for thoughtful investments.
