“…Among the two classifications of instantaneous power theory, one of them has already been described, i.e., instantaneous transformation) is avoided. In this process instead of calculating real and imaginary power, active and non-active current is computed from abc phase voltage and currents [13].…”

The basic aim of the electric power sector is to produce power as when required at the suitable sites, then transmitting and distributing to various load centres or consumers, retaining the quality (sustaining frequency and voltage at stated value) and fidelity of supply at an economical tariff. The primary purpose is to have a brief idea about various power quality advancement techniques and to learn the prospects of various harmonic mitigation methods with a focus on Sinusoidal current control strategy (SCCS). The SCCS is a time domain control strategy established on instantaneous p-q theory. The control strategy has been elaborated here in details and has been implemented using MATLAB 2016A. The results have been given and described in details explaining efficacy of the above control strategy. Since sinusoidal current control strategy is a simple and effective control strategy it has tremendous potential for application in the Distributed Generation oriented system. Further researches can be extended toward application machine learning techniques for the improvisation of control performance of the active power filters.

“…The operation of SSSC either with or without an external source acts as a cascaded compensating device with output voltage independently controllable of the line current with an objective to increase or decrease the total reactive voltage drop across the line and thereby the transmitted active power is controlled [10][11].…”

This paper deals with Five-Level Flying Capacitor Multilevel Inverter (FCMLI) based Static Synchronous Series Compensator (SSSC) as used for the series compensation of transmission line. Here, voltage is injected in series with the transmission line. It is preferred to other compensating devices because apart from controlling the active and reactive power flow, it helps to damp out unwanted oscillations, such as reducing the Sub-Synchronous Resonance (SSR), Ferro-resonance and thus helps in improving the Power Quality (PQ). Hence, FCMLI is used which helps to ameliorate the output waveform and reduces the auxiliary filtering requirements. Moreover, the control logic for the inverter that has been shown in such a way that voltage stress across each capacitor connected to DC-link voltage is equal. The control logic has been implemented in MATLAB/Simulink environment and the result is shown as there are no SSR phenomena and considerable less line loss.

“…The UPQC system was able to supply reactive power needed to increase power factor, reduce voltage and current distortion and help inject active power by PV into the load. A conceptual study of UPQC on three phase four wire (3P4W) system connected to linear and non-linear loads simultaneously has been carried out [8]. A sinusoidal current control strategy drives UPQC in such a way that the supply system draws a constant sinusoidal current under steady state conditions.…”

This paper presents enhancement of load active power transfer using Unified Power Quality Conditioner-Photovoltaic-Battery Energy Storage (UPQC-PV-BES) system. This system is connected to a three phase three wire (3P3W) system with a voltage of 380 V (line to line) and 50 hertz. The proposed model is also compared with UPQC and UPQC-PV respectively. The parameters investigated are load voltage, load current, load active power, and efficiency. BES functions to save excess energy generated by PV, distribute it to the load, avoid interruption voltage, and regulate the charging process and energy utilization. The fuzzy logic controller (FLC) is proposed and compared with proportional integral (PI) method to control DC voltage variable and input DC reference voltage, to produce a reference current source on hysteresis current controller on shunt active filter in 12 disturbance scenarios (scns). In Scenario (Scn) 1 to 5, the 3P3W system uses three combinations of UPQC with PI controller and FLC, still keeps load voltage and load current above 300 V and 8 A. Whereas in Scn 6, only the UPQC-PV-BES with FLC is able to maintain load voltage and load current higher compared to UPQC and UPQC-PV combinations as 304.1 V and 8.421 A, respectively. In Scn 1 to 5, the 3P3W system uses three combinations of UPQC with PI controller and FLC, capable of producing load active power above 3600 W. Whereas in Scn 6, only a combination of UPQC-PV-BES with PI controller and FLC is able to produce a load voltage of 3720 W and 3700 W, respectively. In Scn 1 to 6, UPQC-PV-BES results in lower efficiency compared to using UPQC and UPQC-PV. However, in Scn 6, UPQC-PV-BES with FLC is able to produce load voltage, load current, and load active power higher than UPQC-PV and UPQC. Thus, the UPQC-PV-BES model using FLC is able to compensate load voltage and load current, as well as to enhance load active power, especially for an interruption on source bus. This research is simulated using Matlab/Simulink.
