Any distribution system with large integration of renewable energy based dispersed generations exposed to   several difficulties clearly appeared while evaluating complex large-scale system Available Transfer Capability (ATC), where it is considered as one of the indices reflecting levels of reliability and security for power systems. This paper presents a review of ATC determination of the hybrid wind connected system using Probabilistic Collocation Method (PCM) under transient stability, voltage constraints. Applications of PCM technique in several electrical fields of power system transient-state evaluation are also debated, compared with Monte Carlo method. The first results shows the vast time saving obtained using PCM, with satisfied accuracy. The main goal of the review is to exploring different available usages of PCM technique and their corresponding suitable so that a reasonably precise and effective PCM algorithm can be determined for the concerned system, the relevant theory is outlined here, and unpretentious examples are applied to illustrate the applicability computation of ATC value implementing PCM method, as well as an example with a more credible power system, are obtainable. The feasibility of the suggested method would be validating through in the IEEE-24 RTS bus system.

Reliability of network is need of the hour in the present power system market and is constrained by capability of the network. The network calculations are performed using accurate and high efficient strategies. In order to perform power transactions in the system, the computation of available transfer capability is essential which a metric of capability of the system. Generally, effect wattless power is not taken into account in the methodologies for computation of linear available transfer capability. In this paper, a methodology which considers the reactive power flows for enhancement of linear ATC is presented. In order to perform analysis theoretically, a standard IEEE 3 bus system is considered. Another case study i.e., 14 bus system available in IEEE test systems is used for simulation analysis. FACTS technology is incorporated in the existing system in order to enhance capability of the network. To facilitate transfer maximum power in the system, an optimal power-flow-based ATC enhancement model is formulated and presented along with simulation results. Studies based on the IEEE 3-bus system and 14-bus systems with TCSC demonstrate the effectiveness of FACTS control on ATC enhancement.

Abstract This paper presents a methodology to evaluate transient stability constrained available transfer capability (ATC). A linear and fast line flow–based (LFB) method was adopted to optimize the ATC values. This enabled the direct determination of the system source–sink locations. This paper formulated different market transactions considering bilateral and multilateral impacts in the stability constrained ATC. The proposed method was demonstrated on the WECC 9-bus and IEEE 39-bus systems. The critical energy performance index (CEPI) enabled the direct identification of candidates for contingency screening based on ranking. This index helped to reduce the list of credible contingencies for ATC evaluation and, therefore, the computation time. The results of the proposed ATC method are consistent with the literature and can be deployed for fast assessment of the impact of transactions in an electric power system.

Due to increase in population and industrial growth, insufficient energy resources to generate or transmit the power in power system, increase in load causes power demand in the electrical power system. These power demand leads to voltage instability, increase the losses, reduces the power transfer capability and stability of the power system. To overcome this stability problem FACTS devices are optimally located in the power system to examine the stability of the system. To locate the FACTS devices different optimization algorithms are used in order to improve the stability of the electrical power system.
