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 proposed methodology focuses on drawing the sinusoidal current from the supply system even the presence of nonlinear loads in the system draws harmonic current. The harmonic power is provided by the Shunt Controller of UPQC, to restrict the harmonic components to be pulled at the supply, where as the series component is able to balance the voltage related problems such as unbalancing. The UPQC deals with the load harmonic power and the zero sequence power as well resulting to imbalance in the power system, additionally compensating the reactive power, so that the source voltage and the compensated current both will be in phase. The system performance under variable solar irradiance condition has been observed to be invariable. Keyword-UPQC, Phase Locked Loop, DC-link capacitor, Sinusoidal Current Control Strategy I. INTRODUCTION Now a days the necessity of alternative energy sources has given rise to concepts called Smart Grid and Microgrid. These two terms though are forms of power grid, have varied structure and perform with different degree of preparedness with respect to stability, quality and reliability of power being delivered. Stability is the ability of the power system to restore to normalcy after subjected to small or large disturbances. Good quality of power must have low interruption frequency, limited magnitude and period of over and under voltages along with less harmonic distortion, low flicker in the voltage at supply end, as well as less percentage of phase unbalancing and supply frequency fluctuation, etc. Reliability is the ability to supply continuous electricity irrespective of the demands of the consumers, even during disturbance conditions. In the present scenario the nature of electricity demand is various. Besides being fluctuating in nature the loads now a days are not free from distortions. In particular applications of Power Electronic controllers for various load equipments are mainly liable for poor quality of power. Besides the use of household Inverters and other such electrical equipments are the main culprits in this regard. Besides this there is an increasing competition among renewable energy generation industries to inject more power into the power pool, due to the nonavailability of large energy storage equipments. Since the renewable sources generate electricity at low cost, it's quite obvious to use them as the primary sources, though not always. So all these issues are putting onus on the power engineers to develop the compensating equipments that would mitigate the problems. Power Quality issues related to load voltages are sag, swell, unbalance, flicker, harmonics, etc. Similarly various Power Quality issues related to supply current are harmonics, unbalance loading, etc. The load has always the tendency of drawing the current depending on its type, irrespective of supply voltage to meet the requisite power demanded. Particularly the non-linear type of loads have tendency of drawing harmonic current and certain loads also draw unbalanced current, leading to disturbances in supply current. Since the current has to be generated by the supply system generator, it has to produce harmonic voltage to meet the power needed [1]. In case of non-stiff sources (sources with high input impedance) harmonic voltage gets introduced into the system. This problem is less severe in systems with stiff sources. But our practical system consists of mostly non-stiff sources. Besides this another reason for introduction of harmonics is imperfections of PWM control circuitry. In particular DG integrated systems with lower fault levels, there is increased vulnerability of system to harmonic penetration. Such PQ problems may be mitigated by using a custom power devices. Custom power is relevant to the use of power electronic controllers for distribution systems. Under this scheme an end consumer receives a prespecified quality power. It not only meets the rising demand, but improves the quality and fidelity of power supply. Out of several Custom Power devices Unified Power Quality Conditioner (UPQC) is quite popular. UPQC is a combination of SAF and ShAF, commonly known as UPQC. As the name suggests, it is concerned
