“…Control algorithms play a crucial role in controlling the output voltage of the system. They control by generating switching signals for inverter switches [19]. There are many control algorithms like sinusoidal pulse width modulation (SPWM) as well as space vector modulation (SVM) [20] and many more, which are classified according to different criteria [21].…”

The deviation from the ideal waveform causes disturbances and failure of end-user load equipment. Power traveling a long distance from the generation plant to the end-user leads to deterioration of its quality, and the intensive utilization of power leads to serious issues in the grid resulting in power quality problems. To make the system effective and able to meet modern requirements, flexible AC transmission system (FACTS) devices should be installed into the grid. The interline power flow controller (IPFC) is the latest FACTS device, which compensates for both active and reactive power among multi-line systems. The converters used in the IPFC are crucial as they can be adjusted to regulate the power flow among the lines. This paper proposes a cascaded IPFC with hysteresis and proportional resonant voltage controllers. Some main drawbacks of controllers like steady-state errors and reference tracking of converters can be easily achieved by the PR controller, which makes the system efficient and can be used for a wide range of grid applications. Hysteresis and PR controllers are explained in detail in the following sections. A comparative analysis is carried out among control algorithms to choose the suitable controller which maintains stability in the system.

“…The UPFC is one of the FACTS family members with very versatile uses [18][19][20][21], it has the ability to control the transmission line parameters (voltage, impedance, and phase angle) at the same time. It consists of two converters: series converter and a shunt converter are connected by a common DC link capacitor, which can simultaneously control the transmission line active and reactive power flow as well as to UPFC bus voltage [22][23][24]. This paper presents a simulation study of UPFC, connected with four busses (B1, B2, B3 and B4) system of 100-MVA, 500 KV and two of three-level 48-pulse GTO based converters in order to eliminate the harmonics and decrease the total harmonic distortion (THD).…”

The Power quality of the electrical system is an important issue for industrial, commercial, and housing uses. An increasing request for high quality electrical power and an increasing number of distorting loads had led to increase the consideration of power quality by customers and utilities. The development and use of flexible alternating current transmission system (FACTs) controllers in power transmission systems had led to many applications of these controllers. A unified power flow controller (UPFC) is one of the FACTs elements which is used to control both active and reactive power flow of the transmission line. This paper tried to improve power quality using a fuzzy logic controller (FLC) based UPFC, where it used to control both active and reactive power flow, decreas the total harmonic distortion (THD), correct power factor, regulate line voltage and enhance transient stability. A comparison study of the performance between the system with a conventional PID controller and FLC has been done. The theoretical analysis has been proved by implementing the system using MATLAB/SIMULINK package.The Power quality of the electrical system is an important issue for industrial, commercial, and housing uses.

“…However, the well-known disadvantages of the conventional PI and their adaptive versions encourage researchers to apply the intelligent controllers such fuzzy logic, neural network, neurofuzzy, etc. Among the main advantages of intelligent controllers for grid connected inverter system [6][7][8][9][10][11] are: their ability to deal with any non-linearity of arbitrary complexity and their designs do not require a mathematical model of the system and theoretically. Thus, the intelligent controllers are ideally suited for controlling grid connected inverter system.…”

Phase angle detection of the grid voltage is an imperative part of control in most applications, especially for the synchronization of the current injected by the grid-connected photovoltaic inverters. Consequently, fast and accurate detection of the phase angle, frequency and amplitude of the grid voltage are indispensable data to ensure a correct generation of reference signals and operation of the grid connected inverters. We present in this work a new phase-locked loop (PLL) method for single-phase systems. The novelty is to generate an orthogonal voltage system using a second-order generalized integrator (SOGI), followed by a Park transformation, whose quadrature component is forced to zero by the fuzzy logic, in order to obtain rapid detection and a more accurate picture of the phase angle. Furthermore, simulation results with PSIM software will be submitted to verify the performance and effectiveness of the proposed method strategy. Finally, the experimental test will be used to extract the result and discuss the validity of the proposed algorithm.
