Power Transfer Capability Recognition in Deregulated System under Line Outage Condition Using Power World Simulator

Abstract

The major challenges in deregulated system are determination of available transfer capability on the interconnected transmission lines. Electricity industry deregulation is the required for creating a competitive market throughout the world, which instigate new technical issues to market participants and Power System Operators (PSO). Power transfer capability is a crucial parameter to decide the power flow in the lines for further transactions and the estimation of Transfer Capability decides the power transactions based on the safety and ability of the system. This parameter will decide if an interconnected network could be reliable for the transfer of bulk power between two different areas of the network without causing risk to system consistency. The Power Transfer Distribution Factor (PTDF) is the sensitivity index, which decides the transfer capability in the interconnected network under deregulated power systems. This experiment is conducted on IEEE-6 bus system using Power World Simulator to determine the transfer capability in deregulated system under line outage condition.

Probabilistic Assessment of Available Transfer Capability Incorporating Load and Wind Power Uncertainties

“…Several studies in the literature review examine ATC value, and the proposed computation approaches are primarily divided into deterministic and probabilistic methods. Related efforts employing deterministic approaches such as the continuation power flow method, optimal power flow methods, repetition power flow method, and linear approximation methods are discussed in [3]- [10]. Recently, because various power system factors are unpredictable, probabilistic techniques are increasingly being employed to estimate the statistical characteristics of ATC by accounting for uncertainties such as load fluctuation, generator dispatch, transmission line interruption, and renewable energy intermittency.…”
