Utility restructuring, technology evolution, public environmental policy, and expanding power demand are providing the opportunity for microturbines and fuel cells to become important energy resources. Deregulation has begun to allow for the provision of various ancillary services, such as load-following. In order to investigate the ancillary services ability of these units in distribution syst...

A study of the impact of coin8urance on phye& ciun 2li8it8, physician expense, ancillary 8e?YJiCe8, and ancillary services eopense. When a SQ-percent coinsurance rate was introduced to the Palo Alto Group Health Plan, the members’ demand for me&al care wa8 significantly reduced, other thing8 remaining the 8ame. Th,i8 study differ8 from the preceding article in that it hold8 all other oariableo ...

Demand response is a key element of future power systems due to its capacity defer grid investments, improve demand participation in the market, and absorb renewable energy source variations. In this regard, can play an important role delivering ancillary services systems. The lack standardization programs prepared for traditional generators have blocked these services. Nowadays, increasing nee...

Statistics from the 1978 survey of the National Inventory of Family Planning Services are presented on demographic and institutional characteristics of service sites that provide medical and nonmedical family plannlng services. Data are given on the physical location of the service sites, their operating responsibility, the number of patients served, medical and ancillary services provided, and...

This article provides an overview of neonatal intensive care unit (NICU) treatment costs. It discusses data sources as well as the methods for measuring costs, contrasting the strengths and weaknesses of alternate approaches. In addition, detailed information on NICU treatment costs is presented from a nationally representative sample of 25 hospitals with NICUs. The sample consists of 3288 very...

In this paper, impacts of various uncertainties such as random outages of generating units and transmission lines, forecasting errors of load demand and wind power, in the presence of Demand response (DR) programs on power generation scheduling are studied. The problem is modelled in the form of a two-stage stochastic unit commitment (UC) which by solving it, the optimal solutions of UC as well...

To examine the type and effectiveness of various strategies used by Royal Australian Air Force (RAAF) fast jet (FJ) aircrew in self-referral and management of flight-related neck pain, a 6-section, 18-question survey tool was distributed to 86 eligible RAAF aircrew. Selective results from the sections evaluating aircrew demographics, incidence of flight-related neck pain, and the self-referral ...

This paper integrates Discrete Particle Swarm Optimization (DPSO) and Sequential Quadratic Programming (SQP) to propose a DPSO-SQP method for solving unit commitment problems ancillary services. Through analysis of services, including Automatic Generation Control (AGC), Real Spinning Reserve (RSR), Supplemental (SR), the cost model was developed. With requirements energy balance, operating cons...

Wind energy is producing a larger share of power on many utility grids as more wind turbines are installed, providing motivation for wind turbines to provide ancillary services that are necessary for power grid reliability. The ancillary services considered in this paper consist of actively controlling the power output of the wind turbines to track power set-point commands, participate in frequ...
