An Accurate Power Flow Method for Microgrids with Conventional Droop Control
Energies, 2022 With conventional droop control, the droop relationship between the voltage and reactive power is not purely linear because of the filter reactance. This paper focuses on the theoretical analysis to account for this characteristic and presents a precise ...

Autonomous Control of Electric Vehicles Using Voltage Droop
EnergiesThe surge in electric vehicles (EVs) in Denmark challenges the country’s residential low-voltage (LV) distribution system. In particular, it increases the demand for home EV charging significantly and possibly overloads the LV grid. This study analyzes the impact of EV charging integration on Denmark’s residential distribution networks.
