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

2. Frequency Stability of Power Electronic Based Power System with 100% Renewable Energy.
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The modern power system is aiming to progress away from conventional synchronous machine based power generation towards converter dominated system that leads to extensively high penetration of renewable energy such as wind and PV. This transition of modern power system toward converter based renewable energy comes with new challenges as the conventional synchronous generation is being replaced by converter based power system (CBPS).

3. Decentralized Secondary Frequency Control in an Optimized Diesel PV Hybrid System
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : This research argues that a diesel-based isolated electrical system can be optimized byintegrating a high share of solar photovoltaic (PV) generation and that the frequencystability of such system can be improved by including the PV participation in frequencyregulation. A case study is developed in order to explore an island’s expansion of theinstalled generating capacity and its optimization. READ MORE
