Energy storage is one of the key means for improving the flexibility, economy and security of
power system. It is also important in promoting new energy consumption and the energy …

The last few decades have seen renewable energy source (RES) integration growing at a
rapid pace and this trend is likely to continue. The displacement of conventional …

This paper presents a comparison of the small-signal stability properties for virtual
synchronous machines (VSMs) with dynamic and quasi-stationary representation of the …

Renewable energy sources normally provide low inertia, which allows a little time for
controlling the system. The inertia emulation has recently been introduced for photovoltaic …

In a DC microgrid (DCMG), the DC bus voltage is vulnerable to the power fluctuations
caused by the variations of intermittent renewable energy sources and local loads. A …

Currently, there is a large-scale penetration of renewable energy sources (RES) in power
systems around the world, most of which are based on the power converter technology. The …

Owing to generation and demand mismatch, the frequency deviation and the rate of change
of frequency (RoCoF) may become drastic at times in an islanded microgrid. This is due to …

Microgrids based on renewable energy require energy storage systems to mitigate the
power imbalances that arise due to variable and intermittent nature of renewable sources …

Remote areas that are not within the maximum breakeven grid extension distance limit will
not be economical or feasible for grid connections to provide electrical power to the …

The objective of this study is to optimise the use of virtual inertia given a virtual inertia budget
and a network topology. Following a brief investigation into inertia distribution, it was …
