“…In a gridconnected PV system, a group of PV modules are configured in parallel and in series (Nss x Npp modules) to produce a PV array to generate the required current and voltage. The output of the PV array varies according to the inputs represented by solar radiation and temperature, where the standard inputs according to standard test conditions (STC) are 1000 W/m 2 of solar radiation at a temperature of 25 o Celsius [18]. In this study, the researchers modelled the PV cell circuit after combining the source current (Iph), parallel resistance (Rp), and the series resistance (Rs).…”

Distributed generation (DG) based on a photovoltaic system (PV) connected to a power system is a very promising solution to meet the present demand for energy and to reap the advantages of using clean energy. With the exponential increase in the deployment of distributed energy sources based on renewable energy, the reactive power drawn from the grid has increased dramatically compared to the active power. This affects the quality of the power from the network. Reactive power is usually required to regulate the power factor and the grid voltage so as to improve the ability of the system to handle power. In this paper, the reactive power capability of a PV inverter connected to the grid was determined using the MATLAB/Simulink program. The amount of active power and reactive power injected into the network were independently controlled by their reference values. The study showed the effectiveness of the effect of injection/absorption of reactive power on raising/lowering voltage and improving power quality by reducing the Total harmonic distortion of the voltage and current under different operating conditions.

PurposeSilicon photovoltaics technology has drawbacks of high cost and power conversion efficiency. In order to extract the maximum output power of the module, maximum power point (MPP) is used by implying the nonlinear behavior of I-V characteristics. Different techniques are used regarding maximum power point tracking (MPPT). The paper aims to review the techniques of MPPT used in PV systems and review the comparison between Perturb and Observe (P&O) method and incremental conductance (IC) method that are used to track the maximum power and gives a comparative review of all those techniques.Design/methodology/approachA study of MPPT techniques for photovoltaic (PV) systems is presented. Matlab Simulink is used to find the MPP using P&O simulation along with IC simulation at a steady temperature and irradiance.FindingsMATLAB simulations are used to implement the P&O method and IC method, which includes a PV cell connected to an MPPT-controlled boost converter. The simulation results demonstrate the accuracy of the PV model as well as the functional value of the algorithms, which has improved tracking efficiency and dynamic characteristics. P&O solution gave 94% performance when configured. P&O controller has a better time response process. As compared to the P&O method of tracking, the incremental conductance response rate was significantly slower.Originality/valueIn PV systems, MPPT techniques are used to optimize the PV array output power by continuously tracking the MPP under a variety of operating conditions, including cell temperature and irradiation level.
