Secondary control for reactive power sharing in droop-controlled islanded microgrids [PDF]
2012 IEEE International Symposium on Industrial Electronics, 2012 This paper focuses on the islanded operation of microgrids. In this mode of operation, the microsources are required to cooperate autonomously to regulate the local grid voltage and frequency. Droop control is typically used to achieve this autonomous voltage and frequency regulation.

Exponential-function-based droop control for islanded microgrids
Journal of Modern Power Systems and Clean Energy, 2019 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 ...

Optimal Adaptive Droop Control for Effective Load Sharing in AC Microgrids [PDF]
, 2016 During the past few years, microgrids (MGs) have been becoming more attractive as effective means to integrate different distributed energy resources (DERs). To coordinate active and reactive power sharing among DERs, conventional droop control method is

Demonstration of sustained and useful converter responses during balanced and unbalanced faults in microgrids [PDF]
, 2012 In large power grids where converter penetration is presently low and the network impedance is predominantly reactive, the required response from converters during faults is presently specified by phrases such as “maximum reactive output”.
