“…After the connection of the PV systems to the grid, the reverse power flow due to the supply-demand imbalance was mentioned and possible solution for the situation can be fixed with the control of P-Q and Q-V in [14]. In [15], the solar inverter was used as a harmonic and reactive power compensator. The active-reactive power production balance of the inverter output was controlled in [16][17][18].…”

One of the most studied and funded renewable energy sources is solar energy, all over the world. Solar panels are used to obtain electrical energy from the sun. They should be used effectively due to their expensive structure and challenging installation. However, as the sun light only reaches to the earth during daylight hours, solar systems cannot generate active power during the night, or in cases where daylight is not enough, the whole power capacity of the solar inverters have not been used. In this study; it was shown that in addition to the active power generation during the daytime hours, the solar systems were able to generate reactive power with the remaining capacity of the inverter. Thereby adjusting the grid voltage was provided by the solar system's reactive power control. Designed solar system generates completely reactive power at nights. Thus, the efficiency of the solar systems has been increased by ensuring that the solar systems have used to keep the grid voltage within the values, which stated in the standards, by producing reactive power as well as active power. Matlab/Simulink was used to model the system when using hysteresis band method for system control.

“…To extract the power from solar panels, various power electronic converters are employed. The grid-connected solar photovoltaic (SPV) systems can be classified as single-stage [2,3] and double-stage systems [4][5][6]. A single-stage SPV system uses only a dc-ac voltage-source converter (VSC), in which the solar panel terminals are directly connected to VSC's dc terminals.…”

This study deals with the control and implementation of a dual converter-based grid-tied three-phase solar photovoltaic (SPV) system with series and shunt compensation capabilities. The SPV system consists of two back-to-backconnected voltage-source converters, namely neutral and shunt converters. The purpose of neutral converter is to provide voltage compensation services. The neutral converter does not use any series transformer to provide voltage compensation and makes use of the distribution transformer available at the site. The shunt converter delivers the solar power to the utility grid and the local loads. Moreover, the shunt converter provides the compensation of harmonic and reactive currents generated by the local loads. A new harmonics detection method and control algorithm are developed using adaptive noise suppression-based adaptive filters and implemented for the control of dual converter-based SPV system. The performance and efficacy of the dual converter-based SPV system and its control are demonstrated using MATLAB-based simulations and hardware-in-the-loopbased experiments.

Summary In this paper, a developed voltage control method for distributed single‐phase photovoltaic (PV) generators in unbalanced distribution networks is proposed. The reactive power capability of the PV inverters has been used to regulate bus voltages during irradiance or load variations. The amount of the reactive power required to optimize phase voltages is calculated using fuzzy logic control function, and hence, the power factor is precisely determined. The proposed control for the PV inverters is based on the dq‐current control to regulate the DC bus voltage and the amount of the reactive power. A hysteresis current control is used as a pulse width modulation gate generator. The proposed control precisely determines the amount of the required reactive power to regulate the system bus voltages to lie within standard limits. The efficiency of the proposed control is evaluated with a 10‐node, 5 kV/phase unbalanced three phase distribution system. The analysis includes different test cases under transient and steady state operations to ensure accurate representation of the actual system. The obtained results assess the quality of the network voltages of the studied system regarding voltage levels and the degree of the unbalance. Moreover, the proposed control is capable of operation under different power factors of the PV inverter.
