The presence of high levels of Renewable Energy Resources (RES) and especially wind power production poses technical and economic challenges to System Operators, which under this fact have to procure more Ancillary Services (AS) through various balancing mechanisms, in order to maintain the generation-consumption balance and to guarantee the security of the grid. Traditionally, these critical services...
A somewhat novel approach is presented in this paper to predict, analytically, the vortex-induced vibration (i.e. Aeolian vibration) of an overhead power line's single conductor due to wind. An analytical solution is derived to the basic problem of the Aeolian vibration of a conductor span with equivalent supports on both ends by using the energy balance principle as well as the semi-empirical equations...
■ Positive impact on transient voltage performance from inverter-based generation - better damping and faster voltage recovery due to low inertia and faster controls (if a PV plant regulates voltage) ■ For large system studies, very detailed models of the generators are not necessary ■ Without Low Voltage Ride Through Capability (for example, with large amount of distributed solar PV), loss of large...
