Abstract-The Modern Power System faces new problems and challenges due to restructuring of power systems. Congestion and voltage stability issues are major impact on the present modernized electric power system network. In the modern electric power system network, utilization of Transmission lines are maximized close to or beyond their thermal limits to satisfy the increased power consumption and trades due to unexpected power transactions. If such unplanned power exchanges were not controlled, the power flow on some transmission lines may become overloaded. This phenomenon is called as congestion. Congestion also occurs due to failure or outage of transmission lines in power system. One of the most challenging problems to operate power system in stable condition is overloading of transmission lines by the private entities. The establishment of Flexible-Alternating-Current-Transmission-System (FACTS) devices is more encouraging in relieving congestion, regulates the power flow and upholds the stableness of the electric power system network. Thyristor Controlled Series Compensation (TCSC) device is utilized to relieve congestion and regulate voltage stability of the system. In this research paper alleviation of overloading of transmission lines is carried out in a newly developed fourteen bus test system by interrupting a transmission line. The fourteen bus test system is modeled and simulated using Matlab-Simulink software. The simulation process is carried out under testing condition of fourteen bus system with one line interrupted and improved the performance of system with TCSC.

“…In this, the optimal generators rescheduling has been obtained for three block bid structure submitted to the ISO in a day-ahead market. In [2], an attempt on congestion management by considering the impact of constant current, impedance, and power (ZIP) load model along with the load variation pattern in a day-a-head hybrid electricity market. In [3], methods to the relieve congestion by generation rescheduling and/or load shedding under sever congestion are presented.…”

Abstract:The power system becomes more severe under contingency conditions. In general, the contingencies may be outage of transmission lines or generators. To identify the effect of outages on system security, the contingency analysis is one of the analytical tools. The congestion on a system must be manages using generation rescheduling and with the proper control of the compensation equipments. The transmission line outage sometime increases the total power system losses, cascading outage of transmission lines, etc. Finally, the system leads to collapse condition. To avoid this type of uncontrolled condition, the power system security needs to be analyzed under transmission line outage condition. In this paper, the most critical transmission lines are identified using line collapse proximity index values and the system severity is analyzed in terms of transmission line loadings, bus voltage magnitude variations are tested on standard IEEE-14 bus test system and the analytical results are presented in numerically and as well as graphically.

“…Whenever transmission network congestion occurs how it segregates the wholesale electricity market and forces the market to change its price from a common market clearing price to locational market price [4]. The voltage profile become poor during peak loading of the network and can lead to congestion during such events [5]. The security of the transactions has become essential in the new environment for better planning and management of competitive electricity markets.…”

Congestion is termed as the operating condition in which there is not enough transmission capacity to Contribution/ OriginalityThe paper's primary contribution is to find MCP and LMP for Pool based transaction. The Congestion so addressed by the real and reactive power rescheduling bids of generators. The revised rates for MCP and LMP are calculated. It is obtained that the congestion is relieved in problem under study.
