Methods to ensure the adequate primary frequency response of low inertia power systems
… systems with lower inertia and reduced governor response. The expected continuation of this decline motivates research on economical methods to ensure primary frequency response (PFR) adequacy and prevent frequency-related emergency actions. This dissertation describes both demand-side and …

Nonlinear acoustics in the presence of an object with sum or difference frequency sensing
… occurs at sum or difference frequencies of the primary fields and naturally breaks into (A) nonlinear waves generated by wave-wave interactions, and (B) second-order scattered waves that include the effect of centriodal motion of the object driven by a complete second-order wave-exciting force. …

Wind farm simulation modelling and control
… farm controller design with the objectives of primary frequency response and power optimisation has also been investigated.

Valuing of inertia and fast-acting storage devices in interconnected power grids
… result in: 1) less inertia and maybe worse primary frequency responses (from transient stability perspective of view); 2) stricter ramping requirement (from system operation perspective of view). Fast-acting storage devices can provide both energy and ancillary services through some specific …

Droplet behavior on superhydrophobic surfaces: Interfaces, interactions, and transport
<p>The primary objective of the present work is to study droplet dynamics on smooth hydrophobic and textured superhydrophobic surfaces, and to understand the dependence of interfacial interaction mechanisms on surface morphology. ^ A detailed understanding of the dynamics of droplet response to an …
