En fallstudie i jämn effektförbrukning i Ramsjö Backe: Smarta elnät och möjligheten till helt jämn förbrukning

Abstract [en]

In November 2016 all nations agreed to the COP21 Paris agreement, which binds the

nations to combat a global temperature rise above 2 degrees Celsius during this

century. For this to become reality, modern technologies, such as solar power,

electrical vehicles and energy storage, will have to pave way for feasible, sustainable

societies. Smart grids could be one of the solutions to how to integrate modern

technologies into our conventional electricity grids. If we manage to cut peak

electricity demand and achieve an even electricity demand, renewable energy

investments become more feasible while other services for the grid owner are

provided.

In this paper it is investigated what capacity of battery storage that is required to

achieve an even electricity demand in a local electrical grid with solar power, demand

response and electrical vehicles. Further, an economical analysis of the required

battery storage is made by comparing investment costs to potential savings for the

end customer, energy trading company and grid owner. The investigation is made by

performing a case study in Ramsjö Backe outside Uppsala. Two models are created,

one aggregated model containing the whole residential area and one containing a one

single family building. The results show that in the aggregated model a 4.03 MWh

battery storage was required to keep an even electricity demand 90 % of the year,

and for the building a 108 kWh battery storage was required. Results from both

models show that it is not economically feasible today to invest in even electricity

demand in local electrical grids.
