A widely embraced approach to mitigate the dynamic degradation in low-inertia power systems is mimic generation response using grid-connected inverters restore stiffness of grid. In this article, we seek challenge and advocate for a principled design based on systematic analysis performance trade-offs inverter-based frequency control. With aim, perform qualitative quantitative study comparing e...

The frequency droop response of conventional turbine driven synchronous generators with respect to load increases is normally used in order to have stable operating characteristics for multiple generators operating in parallel over large geographical regions. This presents a challenge for renewable energy sources that interface to the transmission grid through static inverters that do not exhib...

This paper addresses the problem of dynamic frequency control in a diesel-based mini-grid. It is shown that a virtual synchronous machine (VSM) can support dynamic frequency control by adding virtual inertia and damping to the system. However, it is found that the typical formulation of damping power does not work properly when the grid forming gen-set operates in droop mode because of the unkn...

In an islanded microgrid, while considering the complex nature of line impedance, the generalized droop control fails to share the actual real/reactive power between the distributed generation (DG) units. To overcome this power sharing issue, in this paper a new approach based on feed forward neural network (FFNN) is proposed. Also, the proposed FFNN based droop control method simultaneously co...

The Droop quota is traditionally rounded up to the next integer. It has been pointed out by Lundell and Hill that this can have negative consequences. We give two further examples of such consequences, showing that rounding the Droop quota can cause violations of monotonicity and proportionality. This supports the conclusion by Lundell and Hill that it is better to use the exact Droop quota wit...
