Virtual Resistance Tradeoff Design for DCMG Grid-Forming Converters Considering Static- and Large-Signal Dynamic Constraints
TL;DR: It is found that virtual resistance influence on system stability is opposite to that on voltage deviation; thus, a tradeoff method based on the containment principle is developed.

Voltage and frequency stability analysis of AC microgrid
TL;DR: In this article, the authors mainly analyzed the micro sources with different types of loads and dispersion characteristics in different operating modes using droop control method and showed that the droop-control method is necessary to bring the system instability while providing efficient and robust electricity to the micro grid.

Control of parallel connected inverters in stand-alone AC supply systems
TL;DR: In this article, a control scheme for parallel-connected inverters in a standalone AC supply system is presented, which uses feedback of only those variables that can be measured locally at the inverter and does not need communication of control signals between the inverters.

Wireless-Control Strategy for Parallel Operation of Distributed-Generation Inverters
TL;DR: Adapt virtual output impedance is proposed in order to achieve a proper reactive power sharing regardless of the line impedance unbalances and can be properly shared due to the addition of a current harmonic loop in the control strategy.
