1. 1. System impact of micro-production

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Annie Haraldsson; [2023]
   Keywords : Fault ride through; LVRT; micro-production; solar production; photovoltaics; fault simulation; network modeling; power system disturbances; PMU-registrations; fault analysis; Technology and Engineering;

   Abstract : The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-requirements in the RfG.

3. 2. Battery Storage as Grid Reinforcement for Peak Power Demands

   University essay from Linköpings universitet/Energisystem

   Author : Jesper Hilleberg; [2023]
   Keywords : Battery Storage; Battery Energy Storage System; Grid Reinforcement; Flexibility; Lithium-ion battery; li-ion battery; Large Scale Grid Storage; BESS; Energy Storage; Peak Power Demand; Batterilagring; Batterilagringsystem; Nätförstärkning; Nätförstärkningsåtgärd; toppeffektlaster; Flexibilitet; Flexibilitetslösning; litiumjonbatteri; li-ion batteri; BESS; energilagring;

   Abstract : An increased amount of intermittent electricity production, more electric vehicles (EV), and an overall electrification of society may all cause a higher variability between the balance of supply and demand on the electric grid. Battery storage has been identified as a solution to the emerging problem asit can be charged during hours of low power demand and then discharged to help meet the power demand during peak loads.

4. 3. Kartläggning av klimatarbete och klimatkrav i elnätsbranschen

   University essay from SLU/Dept. of Energy and Technology

   Author : Marcus Blomberg; [2022]
   Keywords : klimatpåverkan; elnät; offentlig upphandling; livscykelanalys; Green House gas protocol; scope 3;

   Abstract : The climate change is a growing issue that is put high up on the agenda for countries as well as businesses. In 2015 both EU and Sweden initiated joint initiatives to actively promote reduction of climate impact and stop the increase in global temperature. READ MORE

5. 4. Techno-economic analysis of Battery Energy Storage Systems and Demand Side Management for peak load shaving in Swedish industries

   University essay from KTH/Kraft- och värmeteknologi

   Author : Benjamin Skog Nestorovic; Douglas Lindén; [2020]
   Keywords : Peak load shaving; battery energy storage system; demand side management; Fast Frequency Reserve market; power tariff; Effektoppsreducering; batterilagringssystem; efterfrågeflexibilitet; Fast Frequency Reserve; effekttariffer;

   Abstract : The Swedish electrical grid has historically been robust and reliable, but with increased electrification in numerous sectors, out-phasing of nuclear power and a high market diffusion of wind power, the system is now facing challenges. The rotational energy in the system is expected to decrease as a result of higher shares of intermittent energy sources, which can affect the stability of the grid frequency negatively. READ MORE

6. 5. Grid Tariff Design for Efficient Utilisation of the Distributor Grid : A qualitative study with actors on the Swedish electricity market

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Matilda Haikola; Malin Söderberg; [2020]
   Keywords : Grid tariffs; Demand response; Time-of-use; Real-time-pricing; Critical-peak-pricing; Distribution grid; Distributed energy resources; Flexibility markets.; Elnätstariffer; Efterfrågeflexibilitet; Distributionsnät; Flexibilitetsmarknader; ;

   Abstract : The Swedish electricity system is transitioning due to the establishment of climate policy goals and trends related to technology and demographics. The transition has resulted in an increased demand for electricity. READ MORE
