Abstract Electrical system frequently finds and issue due to unstable nature and power quality because of, in relation to great number of nonlinear charges. So, there is need to limit inside of these difficulties and produce fine voltage quality concerns. The Flexible Alternate Flow Transmission Systems (FACTS) are the framework made out of static gear works for the AC transmission of electrical energy. Unified_Power_Flow Controls (UPFC) are the excellent FACTS tools to attach series and shunt together and it could use for framing Power transmission sensitive and active power. Here in the paper, Unified Power Flow Control (UPFC) used to clear the voltage sink and Surge. Unified Control was developed and engineered using amplifiers and rectifiers. The real and reactive modifications in congruous control orientations at the receiver side. Use of Simulink of MATLAB checks quality of energy in the use of Unified Control.

This paper presents the modeling and simulation of 14-bus system using TCSC and UPFC. Thyristor Controlled Series Compensator (TCSC) and Unified Power Flow Controller (UPFC) are included in 14-bus system to improve the power quality of the power system. The voltage sag is created by adding an extra load at the receiving end. This sag is compensated by using FACTS devices like TCSC and UPFC. Improvement in the voltage and power are presented using simulation studies.

The developments in power quality are fast and difficult to predict. The majority of power quality issues experienced by industrial customers can be attributed to momentary interruptions, voltage sags or swells, transients, harmonic distortion, electrical noise, and flickering lights, among others. A new device may be invented tomorrow solving power quality problems. The FACTS devices could provide fast control of active and reactive power through a transmission line. The unified power-flow controller (UPFC) is a member of the FACTS family with very attractive features. This device can independently control many parameters, so it is the combination of the properties of a static synchronous compensator (STATCOM) and static synchronous series compensator (SSSC).The performance of AC Transmission system with Unified power flow controller under various power quality problems analysis described. The proposed system is formulated and research work is done by wavelet multi resolution analysis using Bior1.5 mother wavelet with MATLAB/SIMULINK software. It is observed that the effectiveness of AC power transmission through Unified power flow controller under power quality problems of sag, swell, transient, temporary faults and capacitive switching.

Power Flow Controller

Due to the intermittent nature of renewable sources, miss-matching between power generation and load power causes a deviation from the desired voltage and frequency in power supply. To solve this problem, a new control technique has been proposed for the power flow control with the unified power flow controller (UPFC) in grid-connected hybrid renewable energy systems such as photovoltaic-wind. The proposed control technique combines the binary version of the grey wolf optimization (bGWO) and recurrent neural network (RNN). Here, bGWO is utilized to generate the dataset of control signals for shunt and series converters of the UPFC. Based on the accomplished dataset, the RNN technique performs and predicts the optimal control signals of the UPFC. Likewise, the proposed control scheme regulates the voltage deviation and minimizes the power losses simultaneously. Then, the proposed model is executed in Matrix Laboratory/Simulink working stage and the execution is assessed with the existing techniques such as fuzzy logic controller, improved particle swarm optimization and grey wolf optimization. The optimized gain parameters and elapsed time of the proposed and existing technique is also analysed. The optimized gain parameters such as KpKi of the proposed hybrid technique are 2.5 and 150. The elapsed time of the proposed technique is 30.15sec. Overall, the comparison results demonstrate the superiority of the proposed technique and confirm its potential to solve the above-mentioned problems.
