Voltage Stability of Droop - Controlled Microgrids * ( Extended
As the deployment of distributed generation continues, an increasing number of DC/AC power inverters will be interfaced into the electric grid. Groupings of these power inverters, along with distributed storage and load, are referred to as microgrids. Microgrids offer the potential for unprecedented reliability and flexibility, but also pose new control challenges. Inverters in microgrids must ...
متن کاملConditions for stability of droop-controlled inverter-based microgrids
We consider the problem of stability analysis for droop–controlled inverter–based microgrids with meshed topologies. The inverter models include variable frequencies as well as voltage amplitudes. Conditions on the tuning gains and setpoints for frequency and voltage stability, together with desired active power sharing, are derived in the paper. First, we prove that for all practical choices o...
متن کاملDroop-Controlled Inverters in Microgrids are Kuramoto Oscillators ?
Motivated by the recent interest in smart grid technology and by the push towards distributed and renewable energy, we study the parallel operation of DC/AC inverters in a lossless microgrid. We show that the parallel interconnection of DC/AC inverters equipped with conventional droop controllers is precisely described by the Kuramoto model of coupled phase oscillators. This novel description, ...

An Enhanced Droop Control Scheme for Islanded Microgrids
Due to the line impedance impact on islanded low-voltage microgrids, traditional droop control cannot guarantee the proper power sharing between distributed generation (DG) units. In the meanwhile, droop control would cause voltage and frequency deviation, which will influence the power quality of customers. This paper proposed an enhanced droop control scheme with autonomous frequency restorat...
