1. Parallel Operation of Grid-Forming Power Inverters
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. READ MORE

4. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study
University essay from Högskolan Dalarna/Institutionen för information och teknikAbstract : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. READ MORE

5. Estimating CO2 reductions from renewable energy sources : The impact of power system nonlinearities
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Replacing conventional generation with renewable generation in power systems is essential for reducing CO2 emissions. It is important to know how effective renewables are in reducing CO2 emissions. Since CO2 reduction cannot be measured directly, different methods have been used to estimate reduction of CO2 emissions. READ MORE
