Analysis and stabilization control of a voltage source controlled wind farm under weak grid conditions

Frontiers in Energy 2022, Volume 16, Issue 6,   Pages 943-955 doi: 10.1007/s11708-021-0793-5

Abstract: strategy referred to as the voltage source (VS) control.The primary intention of the VS control method is to achieve the high-quality inertial response capabilityTo this end, a frequency domain model of the wind farm under the VS control is first developed.A crucial finding is that the inertial response of VS control has negative impacts on the stability marginof VS control while fulfilling the demand of inertial responses.

Frontiers in Energy 2012, Volume 6, Issue 2,   Pages 184-192 doi: 10.1007/s11708-012-0185-y

Abstract: Thus, it is important that wind turbines also contribute to system frequency control.The modified inertial support scheme is proposed which helps the DFIG to provide the short term transientThe frequency deviation is considered by the controller to provide the inertial control.The optimal speed control parameters have been used for the DFIG to increases its participation in frequencycontrol.

Instrumented toys for assessing spatial cognition in infants

Domenico CAMPOLO, Fabrizio TAFFONI, Domenico FORMICA, Flavio KELLER, Eugenio GUGLIELMELLI

Frontiers of Mechanical Engineering 2011, Volume 6, Issue 1,   Pages 82-88 doi: 10.1007/s11465-011-0208-0

Abstract:

This paper describes an interdisciplinary approach to the assessment on infants’ behavior, with a focus on the technology. The goal is an objective, quantitative analysis of concurrent maturation of sensory, motor and cognitive abilities in young children, in relation to the achievement of developmental milestones. An instrumented block-box toy specifically developed to assess the ability to insert objects into holes is presented. The functional specifications are derived from experimental protocols devised by neuroscientists to assess spatial cognition skills. Technological choices are emphasized with respect to ecological requirements. An ad hoc calibration procedure is also presented which is suitable to unstructured environments. Finally, preliminary tests carried out at a local day-care with 12–24 months old infants are presented which prove the in-field usability of the proposed technology.
