Renewable energy sources are used to accommodate the ongoing increasing power demand. So, the integration of PV system controlled by the revised p-q concept which is revealed from instantaneous active reactive power concept and a suitable choice to meet the energy demand. Enormous utilization of power electronic converters deviates the quality of power. Series voltage compensation and shunt current compensation is done by the p-q theory. Revised p-q conceptstates the single instantaneous active power and the imaginary powers for active and reactive power compensation. This paper presents the revised p-q concept to generate the reference signals for integrated unified power quality conditioner (PV-UPQC-S). This proposed method enables the process of PV-UPQC-S under unbalanced voltage circumstances at the point of common coupling (PCC). This system incorporates the series voltage source converter (VSC) to control the unbalanced voltage by sharing the part of the reactive power of the load, which in turn reduces the rating of the shunt VSC. The integration of the PV system at the DC bus of UPQC serves the purpose of load sharing as well as power quality improvement to maintain the healthy grid condition. This concept is approved by simulating the proposed model in MATLAB/Simulink. The proposed model comprises of both linear and non-linear loads. The experimental results validates the perfect dynamical response of the given model.

“…The reference currents are calculated with the help of calculated reference active and reactive powers of the grid. These reference currents are compared with the source currents to generate the gate signals for the switches of the inverter [115,116]. This control algorithm has fast response with minimum error between calculated and reference signals.…”

Energy generation is facing a big challenge for meeting the load demand during peak hours. Power utilities are heavily depending on fossil fuels due to limited resources of non renewable energy generation. Therefore researchers and scientists are looking towards some distributed generators (DGs) to supply extra power during peak hours of energy curve. Solar power gives them an extra sniff to meet the load demand in that period. As a consequence grid-tied solar Photovoltaic (PV) system catches the eyes of researchers and industrialist mainly for reducing the burden of fossil fuel energy generation. Single stage or two stages PV systems are applicable for grid interconnection with or without battery backup. Double stage system is generally suggested for practical applications as it holds a benefit of power quality improvement. This article presents a comprehensive review on grid-tied solar PV system. The complete architecture of the grid-tied PV system includes the construction of PV array, MPPT methods, DC-DC converters, Inverters and control algorithms. Different control techniques and topologies with their merits and demerits for grid-tied systems are thoroughly reviewed. The comparisons of different conventional and advanced control techniques justify the practicability of this architecture. Different topologies and control methods of grid-tied PV system are studied thoroughly to justify the potential of grid-tied PV system.
