Long-term voltage stability of electric power systems hosting inverter-interfaced energy sources
(2021)
The study of power system dynamics refers to the motion of electro-mechanical and electro-magnetic quantities such as voltages, currents, rotational speeds, angles and powers under the action of forces caused by system disturbances. For decades, such dynamics have been extensively dominated by large Synchronous Generators (SGs). Not a surprising statement, considering that the power systems that we know today were built based on the SG concept since the closing decades of the 19th century. It all began in 1891, when ...

Development of feedback control for energy policy design to guarantee sustainable solar and wind power investment growth
(2021)
Energy transition in the power sector is one of the main pathways to achieving the climate targets. In order to stimulate renewable power development, regulatory policies play a vital role. However, these policies have so far attained only partial results or unexpected consequences due to the unsuitable designs. Therefore, the study addresses the question, “How do regulatory policies have to be designed in order to create a favorable environment for renewable power development?”
This work proposes to use feedback ...
