Hantering av effekttoppar på ett lokalt elnät med batterilagringssystem

Abstract [sv]

Syftet med detta examensarbete har varit att undersöka hur effektoppar kan hanteras i ett lokalnät. Detta gjordes genom simulering av ett batterilagringssystem i Matlab Simulink, med fokus på lastutjämning snarare än elnätets dynamik i stort. Simuleringen baserades på timvis mätdata från uppdragsgivares nätstationer där batterisystemets potentiella påverkan analyserades retroaktivt för att bedöma dess möjligheter. Resultaten visar att ett batterilagringssystem kan bidra till lastutjämning över hela året samt minska topplaster för en transformator vilket kan förlängadess livslängd. Arbetet visar att lokal energilagring har flera potentiella användsningsområden. För att kunna dra mer definitiva slutsatser krävs fortsatt teknisktfördjupning samt en omfattande ekonomisk analys för att fastställa om det finns en ekonomiskt incitament för dessa lösningar.

Abstract [en]

The purpose of this thesis has been to investigate how to handle peak demand in a local grid. This was done by simulating a battery energy storage system in Matlab Simulink, with a focus on load balancing rather than the dynamics of the powergrid. This simulation was built on the hourly measurement data from the companies substations, where the energy storage system’s potential impact was analysed in retrospect to asses its capabilities. The results show that a battery energy storagesystem can contribute to load leveling throughout the year and decrease the peak loads for a power transformer, which may increase its lifespan. The study demonstrates that local energy storage has multiple potential applications. But to be able to draw more certain conclusions, there is a need for further technical studies and a comprehensive economic analysis to determine whether there is a financial incentive for such solutions.
