Enhanced Virtual Synchronous Generator Control for Parallel Inverters in Microgrids
TL;DR: An enhanced VSG control is proposed, with which oscillation damping and proper transient active power sharing are achieved by adjusting the virtual stator reactance based on state-space analyses and communication-less accurate reactive power sharing is achieved based on inversed voltage droop control feature and common ac bus voltage estimation.

A Voltage and Frequency Droop Control Method for Parallel Inverters
TL;DR: In this paper, a new control method for the parallel operation of inverters operating in an island grid or connected to an infinite bus is described, where each inverter supplies a current that is the result of the voltage difference between a reference ac voltage source and the grid voltage across a virtual complex impedance.

Energy storage and its use with intermittent renewable energy
John P. Barton,David Infield +1 more
TL;DR: In this article, a simple probabilistic method has been developed to predict the ability of energy storage to increase the penetration of intermittent embedded renewable generation (ERG) on weak electricity grids and to enhance the value of the electricity generated by time-shifting delivery to the network.

Wind turbines emulating inertia and supporting primary frequency control
TL;DR: In this article, a method is proposed to let variable-speed wind turbines emulate inertia and support primary frequency control, where the required power is obtained from the kinetic energy stored in the rotating mass of the turbine blades.

Robust Power System Frequency Control
TL;DR: In this article, the authors provide a comprehensive coverage of robust power system frequency control understanding, simulation and design, and develop an appropriate intuition relative to the robust load frequency regulation problem in real-world power systems, rather than to describe sophisticated mathematical analytical methods.
