Available transfer capability (ATC) is the transfer capability remaining in the physical transmission network for further commercial activity over and above already committed uses which needs to be posted in the electricity market to facilitate competition. ATC evaluation is a complicated task including the determination of total transfer capability (TTC) and existing transfer capability (ETC)....

In the present research, free convection heat transfer from isothermal concave and convex body shapes is studied numerically. The body shapes investigated here, are bi-sphere, cylinder, prolate and cylinder with hemispherical ends; besides, they have the same height over width (H/D = 2). A Numerical simulation is implemented to obtain heat transfer and fluid flow from all of the geometries in a...

Total transfer capability TTC is an important index in a power system with large volume of inter-area power exchanges. This paper proposes a novel technique to determine the TTC and its confidence intervals in the system by considering the uncertainties in the load and line parameters. The optimal power flow OPF method is used to obtain the TTC. Variations in the load and line parameters are in...

Electric power industries throughout the world have been restructured to introduce competition among the market participants and bring several competitive opportunities. Open access to the transmission system places an emphasis on the intensive use of the interconnected network reliably, which requires knowledge of the network capability. Available Transfer Capability (ATC) is a measure of the ...

The increasing uncertainty level caused by growing renewable energy sources (RES) and aging transmission networks poses a great challenge in the assessment of total transfer capability (TTC) available (ATC). In this paper, novel data-driven sparse polynomial chaos expansion (DDSPCE) method is proposed for estimating probabilistic characteristics (e.g., mean, variance, probability distribution) ...

Till now, many transfer capability techniques are performed in a simplified manner, with limited consideration of security constraints. This is unacceptable as the risks for not evaluating security impacts are high. There have been doubts on whether current techniques could provide secure transfer capability assessment and thus introducing a new challenge. This paper presents an optimal power f...

development of technological capability is one of the effective methods for promoting the firm competitive performance. transfer of suitable technology help the firm to make a strong position in its industry faster than using in-house r&d.; successfulness of a firm based on technology transfer process can be measured with different scales such as measurement of firm competitive performance thro...

Since the development of large scale power grid interconnections and power markets, research on available transfer capability (ATC) has attracted great attention. The challenges for accurate assessment of ATC originate from the numerous uncertainties in electricity generation, transmission, distribution and utilization sectors. Power system uncertainties can be mainly described as two types: ra...
