The TTC is then selected based on the risk concept. The uncertainty of the forecast demand, forecast generation output from the wind power generation system, equipment unavailability, and fault locations is fully realized and integrated into the calculation by means of a probabilistic method, Monte Carlo simulation.

In this paper, the PX model based on the steady-state model of an induction generator for the wind power generation system is proposed. To analyze such impact, the model of wind power generation system is required. As is known, the impact of the wind power generation is mainly attributed to its uncertain generation output strongly depending on the wind speed. This paper primarily focuses on the TTC calculation of a power system with a large penetration of wind power generation.

As a result, it has become necessary to include the investigation of such impact in the analyses. Although this sector offers a number of advantages, a large penetration of this sector may result in an unfavourable impact on the system security and reliability. This sector is expected to continue growing with more installed capacity. Renewable energy offers a number of great appeals due to its sustainability, environmentally friendliness, and as a low-cost resource for the future electricity production. Recently, a rapid growth of generation from renewable energy resources, e.g., wind and solar energies, has been witnessed worldwide. K E Y W O R D S capacity benefit margin, graph theory, multi-area power systems, reliability, wind power generation List of Symbols and Abbreviations: The proposed technique can be employed by utilities for CBM estimation in the presence of renewable energy sources.

Simulations using the IEEE 24-bus reliability test system in MATLAB show that the proposed technique is significantly better in terms of scalability and accuracy as compared to existing techniques. The proposed technique is based on graph theory and can be used to calculate CBM in the presence of multi-deficient areas and renewable energy sources, in particular, WP. To solve these issues, this article incorporates wind power (WP) generation in CBM computation. Moreover, existing techniques for CBM calculation are based on iterative optimization and may not scale well to more than one deficient area. However, despite the global awareness on the continuous shift from conventional power generation sources to renewable energy sources, the assessment of CBM in the presence of renewable energy has not been addressed. Various techniques have been employed in literature to evaluate CBM. It is usually estimated by evaluating the reliability of the generating units of interconnected systems to know the amount of external generation required during emergency supply shortage. Capacity benefit margin (CBM) is the amount of transmission capacity reserved between interconnected systems for emergency power exchange between utilities. According to the tests applied in the Northwest China power network to perform ATC calculation and analysis, this method guarantees more exact results by simulating actual transfer increasing mode of the Northwest China power network.Įnergy sustainability and reliability issues have created great concerns globally, instigating various utilities to create interconnections with one another for system security and techno-economic benefits. In this paper, a combined method including linear distribution factors and repeated power flow (RPF) is proposed to perform ATC calculation, meanwhile, two scenarios can be selected to simulate power transfer increment: One is to increase the total generation output in source area as the load in sink area increases The other is to decrease the same amount of generation in sink area while the generation output in source area is to be increased. Widely used ATC calculation software-Powerworld simulates power transfer increment through decreasing generation output in sink area (receiving-end) using the repeated power flow method, but this simulation model does not accord with the actual circumstances of electricity shortage in China.

In the environment of the power market, available transfer capability (ATC) is a measure of transfer capability remaining in the physical transmission network for future commercial activity over and above already committed uses, then it is an important parameter for all companies participating in the power transmission activities.
