Due to the increased demand on electric power, power systems have become highly stressed. This has caused the frequent occurrence of cascading failures, where the failure of one line leads to a series of failures causing a system blackout. Adding high speed control of different electrical parameters of the power system can help improve the reliability of the power system and relieve some of that stress. In this research, the effects of adding static VAR compensators (SVCs) and distributed generation units has been studied from a reliability perspective. Since installing this equipment can be expensive, an algorithm has been developed to obtain the optimal bus location to install such devices, such that reliability is improved. Furthermore, Monte Carlo simulation is used to provide a measure for the improvement in system reliability in the presence of transmission line failures. Results show that injecting real and reactive power generally improves system reliability. However, increasing the amount of injection and increasing the number of buses injected to indefinitely does not necessarily enhance the reliability of the system any further. As such, caution must be exercised when deploying SVCs or distributed generation sources when the goal is to improve system reliability.

“…The significance of HVDC controller considered as part of UPFC device is a structure of the back-to-back converter that governs the conversion of ac-dc-ac. HVDC is assigned for frequency and phase independent short or long distance overhead or underground bulk power transmission with high speed controllability [32]. This provides greater real power transmission and less maintenance.…”

“…From research findings, power system monitoring, inverter, dynamic voltage regulator (DVR), static synchronous compensator (STATCOM), unified power quality conditioner (UPQC), and energy storage system are approaches that are used in alleviating power quality issues [9]. A UPFC is an electrical device for providing fast-acting reactive power compensation on high voltage electricity transmission networks [10]. UPFC provides power flow control together with independent voltage control.…”

Wind energy conversion systems are the quickest developing renewable source of electrical energy having tremendous environmental and social advantages. In this paper proposed an optimal reactive power dispatch (ORPD) technique of wind power plants in grid connected power system. The ORPD issue is a vital issue in the operation of power frameworks. It is a nonlinear and mixed integer programming issue, which decides ideal qualities for control parameters of reactive power makers to upgrade particular target capacities while fulfilling a few specialized requirements. The ORPD technique consists of ACO and ANFIS controller for improving the performance of multiple wind turbines and the steady state stability of the power system in terms of active and reactive power flow of a transmission line. The ACO algorithm is used to extract the maximum power from WECS. The generated maximum power is transmitted through the UPFC connected HVDC link. The performance of the UPFC is improved with the ANFIS controller based on the actual and the reference power parameters of the grid connected power system. Furthermore, UPFC is utilized to control active and reactive flow of power in a transmission line. The proposed method is implemented in MATLAB/Simulink platform and tested with the different wind speed condition. To verify the effectiveness of the proposed model, the obtained results in the deterministic case is compared with the existing methods like GA and PSO.

“…Recently, interests in high voltage direct current (HVDC) systems has been growing due to interconnection between the mainland and off-shore wind farms [1][2][3], power flow control for alternating current (AC) power girds [4][5][6], long distance transmission, and introduction of the supergrid, which is a large scale power grid interconnected between national power grids [7][8]. For these reasons, development of controllers and protection systems for the various HVDC system applications has been studying.…”
