Mixed-potential-function-based large-signal stability analysis of DC microgrid with constant power loads

open access: yesFrontiers in Energy Research, 2023
With the development of power grid technology, a large number of constant power loads (CPL) are introduced into the power grid system. The negative damping characteristic of CPL poses a great challenge to the stability of power grid under the condition ...

Power Oscillations Damping in DC Microgrids [PDF]

open access: yesIEEE Transactions on Energy Conversion, 2016
This paper proposes a new control strategy for damping of power oscillations in a multi-source dc microgrid. A parallel combination of a fuel cell (FC), a photovoltaic (PV) system and a supercapacitor (SC) are used as a hybrid power conversion system (HPCS). The SC compensates for the slow transient response of the FC stack.
