-----------------------------------------------------------ABSTRACT----------------------------------------------------------It is very important to maintain supply reliability under the deregulated environment. The transient stability problem is one of the major concerns in studies of planning and operation of power systems. Although the equalarea criterion method is useful in determining the ...

Objective. Evaluation of the efficacy of Crest Herbal Crystal Toothpaste in "clearing internal heat." Methods. This was a randomized, double-blind, controlled parallel design clinical test of a product that was already on the market. 72 subjects were randomly assigned to control group (group A with Colgate Herbal Salty Toothpaste) or treatment group (group B with Crest Herbal Crystal Toothpaste...

Supply chain design problems can be analyzed as cooperative linear production games. The maximal total payoff and the optimal coalition of a “market responsive” supply network can be obtained from the solution of the mixed-variables Linear Programming problem. Then, using duality theory, the “Owen set” can be constructed in order to allocate the payoff among the members of the optimal coalition...

Sustained forest management of Cunninghamia lanceolata (Chinese fir) plantations in subtropical China is restricted by the limited availability of quantitative data. This study combines inventory data and tree-ring analysis of Chinese fir from natural and plantation forests that were subjected to controlled burning or brush clearing site preparations. Inter-annual variation of Chinese fir tree-...

In an environment of Over-The-Counter trading with asymmetric information about the quality of the counterparty, we study traders’ incentives to screen their counterparties under different clearing arrangements. When traders can choose the clearing arrangement, they decide which types of transactions to clear under each arrangement, with significant consequences for transparency and collateral ...

As part of the day-ahead market clearing process, MISO solves one of the most challenging Security Constrained Unit Commitment (SCUC) models. With the footprint expansion and increased financial activities, the day-ahead market unit commitment may encounter performance challenges from time to time. This paper reviews MISO’s day-ahead market clearing process and identifies the factors contributi...

as one of the most promising distributed generation (dg) sources, wind power technology has been widely developed in recent years. doubly fed induction generator (dfig) is currently employed as one of the most common topologies for wind turbine generators (wtgs). this generator operates as a synchronous/asynchronous hybrid generators. therefore, it is necessary to power engineers find understan...

The research on electromechanical transient stability of power systems is great significance. Analyzing the parameters simulation system and its improved with typical short-circuit faults, this paper studies improvement. Firstly, based SIMULINK MATLAB, a double-loop single-machine-infinite-bus built. experiments under circumstances three-phase short circuit single-phase grounding faults are the...
