Synchronization and power sharing for droop-controlled inverters in islanded microgrids (2012, critical): “Limitations of the Literature: Despite forming the foundation for the operation of parallel VSIs, the frequency-droop control law (2) has never been subject to a nonlinear analysis [34].”
Synchronization of Parallel Single-Phase Inverters With Virtual Oscillator Control (2014, background): “To overcome shortcomings associated with load-sharing accuracy and system frequency/voltage deviations, recent efforts have focused on the overlay of a communication network between inverters to implement secondary- and tertiary-level controls [17], [26]–[28].”
Secondary Frequency and Voltage Control of Islanded Microgrids via Distributed Averaging (2015, background): “The reference inputs for the voltage loop are supplied by droop controllers, which are heuristic controllers based on active/reactive power decoupling [2], [6], [8], [18], [21].”
Voltage Stability and Reactive Power Sharing in Inverter-Based Microgrids With Consensus-Based Distributed Voltage Control (2016, background): “A quantitative analysis of the error in power sharing is provided in [16] for the control proposed therein.”
Conditions for stability of droop-controlled inverter-based microgrids (2014, methodology): “Then, additional methods such as the virtual output impedance (Guerrero et al., 2005) or alternative droop control laws (Zhong, 2013) could be employed instead of (4).”
Enhanced Virtual Synchronous Generator Control for Parallel Inverters in Microgrids (2017, background): “The idea to use ac bus voltage as a common reference shares some similarities with the approaches presented in [21], [39], and [40].”
Small-Signal Modeling and Parameters Design for Virtual Synchronous Generators (2016, background): “There are related research discussing how to reduce the voltage drop caused by droop effect and load effect [25], [26], and it is not discussed here.”
Droop-Based Distributed Cooperative Control for Microgrids With Time-Varying Delays (2016, background): “Roughly speaking, the basic control strategy for microgrids is the hierarchical control [4], including primary control (droop control) [5], [6], secondary control (restoration of voltage and”
