Achieving the European Union renewable energy source penetration 2030 targets requires an increase in flexible resources to compensate for variability/intermittency of solar and wind generation ensure system safety balancing. Herein, two readily deployable flexibility solutions balance demand/supply as alternative building additional thermoelectric reserves are proposed. How transmission OPERAT...

OBJECTIVE This article reviews the evidence on the relationship between recent increases in utilization of diagnostic imaging and self-referral. The evidence shows that self-referral invariably leads to higher utilization and the attendant higher costs. CONCLUSION Because most physicians do not own advanced imaging equipment, their own best interests are being thwarted by the practice of self...

Physician ownership of in-office ancillary services (IOASs) has come under increasing scrutiny. Advocates of argue that IOASs allow physicians to supervise the quality and coordination of care. Critics have argued that IOASs create financial incentives for physicians to increase ancillary service volume. In this paper we develop a conceptual framework to evaluate the tradeoffs associated with p...

In this paper, we present a systematic exposition of generator-provided reactive support as an unbundled ancillary service under open access transmission. We discuss the nature and salient physical characteristics of reactive support and analyze their implications in acquiring VAr support as one of the ancillary services. The paper provides an analysis of the dominant component in the cost stru...

Automated demand response can be a valuable resource for ancillary services in the power grid. This paper illustrates this value with the first experimental demonstration of frequency regulation from commercial building Heating Ventilation and Air Conditioning (HVAC) systems. The experiments were conducted in a 40,000 sq. ft. commercial building located at the University of Florida campus. Deta...

Materials and methods This poster provides an overview of a unique agencybased integrated outpatient model for treating consumers with Clozaril and reports on 12 years of outcome findings (n = 114). These are the outcomes for the first 12 years of the Spectrum Clozaril Clinic for the period of 1993-2005. The “Spectrum Clozaril Clinic” model is built on an interdisciplinary team approach that em...

The modern low-voltage direct current (LVDC) distribution system merges ICT, power electronics and conventional grid technologies into single system. This paper gives an overview to the LVDC RULES research project and presents its first key results. The foundations of the project are laid by the lessons learned during earlier research projects. Impacts of providing ancillary services for the ne...
