On the stability of inverter-based microgrids via LMI optimization
TL;DR: A decentralized state-feedback control approach for inverter-based microgrids with a linear matrix inequality (LMI) stability condition is proposed, which stabilizes the system, guaranteeing zero steady-state frequency deviations.
Modelling and Forecasting of Photovoltaic Generation for Microgrid Applications: from Theory to Validation
TL;DR: A model-based strategy to reconstruct the maximum power production of a PV power plant is proposed thanks to integrating measurements of the PV cell temperature, system DC voltage, and current, and is shown to outperform available state-of-the-art techniques and are able to capture the fastest fluctuations of small-scale PV plants.

A New Representation based on Virtual Capacitor for Virtual Synchronous Generators
TL;DR: It is shown that while the virtual capacitor shows the same performance as VSG, it gives a different physical representation that can be leveraged for design and study of multi-inverter systems.

Virtual Impedance Shaping for low voltage Microgrids
TL;DR: An outer virtual impedance loop is proposed to shape the output voltage in AC Microgrids to achieve harmonic current sharing and reducing total harmonic distortion (THD) even in scenarios of asymmetric sharing of highly non-linear loads.

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.
