An Improved Droop Control Strategy for Reactive Power Sharing in Islanded Microgrid [PDF]
For microgrid in islanded operation, due to the effects of mismatched line impedance, the reactive power could not be shared accurately with the conventional droop method.

A neural network-based adaptive power-sharing strategy for hybrid frame inverters in a microgrid
The capacitive-coupling inverter (CCI) is more cost-effective in reactive power conditioning and enhanced reactive power regulation ability when compared with the inductive-coupling inverter (ICI).

Decentralized Optimal Servo Control System for Implementing Instantaneous Reactive Power Sharing in Microgrids [PDF]
© 2010-2012 IEEE. Active power is dispatched among distributed generation (DG) units in microgrids (MG) by means of f/P droop control loop, which controls the frequency set-point of voltage source converter (VSI). Since the frequency is a global variable,

Power Management Strategy for Photovoltaic based Distributed Generators Operating in Parallel
In many countries, the grid-code or standards do not allow the Photovoltaic (PV) inverters to exchange reactive power with the grid. Recently, some countries have relaxed the standards.

Exponential-function-based droop control for islanded microgrids
An exponential-function-based droop control strategy for the distributed energy resources (DERs) is proposed to reduce the reactive power-sharing deviation, limit the minimum value of frequency/voltage, whilst improving the utilization rate of renewable ...
