This paper aims to obtain suitable control for the Standalone Photo Voltaic (SAPV) system to meet consumer demands in weather conditions. A SAPV system is developed with a solar array with Maximum Power Point Tracking (MPPT), a Boost converter, and an inverter. This system uses controllers for maximum power output tracking, constant DC output of the Boost converter, and constant output voltage and frequency with Pulse Width Modulation (PWM) control mode. MPPT, boost converter, and inverter controller parameters are designed and tuned, respectively. Proportional gain (Kp) and Integral gain (Ki) values and the Sliding Mode Method (SMC) tune the controller parameters. The innovative aspect of this work is to propose a standalone PV system with controllers based only on the sliding mode control approach. Moreover, the current controller provides an output current of high quality with a THD of 1.6 %. Effectiveness and robustness of the proposed scheme modeled and simulated under OPAL-RT real-time Software in Loop (SIL) platform with MATLAB Simulink under fast variations of irradiance and temperature. Various analyses have been carried out for examining the proposed Sliding Mode Controller-based standalone photovoltaic system.

“…This is achieved by making an optimal follow-up of the maximum power point (MPP), which means keeping the system working at the operation point where the extraction of power is maximum. Therefore, maximum power point tracking (MPPT) techniques are introduced to extract maximum power from PV panels to significantly use the PV panel power [8,9].…”

Non-Linear Sliding Mode Controller for Photovoltaic Panels with Maximum Power Point Tracking

In this paper, nonlinear sliding mode control (SMC) techniques formulated for extracting maximum power from a solar photovoltaic (PV) system under variable environmental conditions employing the perturb and observe (P and O) maximum power point tracking (MPPT) technique are discussed. The PV system is connected with load through the boost converter. A mathematical model of the boost converter is derived first, and based on the derived model, a SMC is formulated to control the gating pulses of the boost converter switch. The closed loop system stability is verified through the Lyapunov stability theorem. The presented control scheme along with the solar PV system is simulated in MATLAB (matric laboratory) (SMC controller and PWM (Pulse Width Modulation) part) and PSIM (Power electronics simulations) (solar PV and MPPT algorithm) environments using the Simcoupler tool. The simulation results of the proposed controller (SMC) are compared with the classical proportional integral derivative (PID) control scheme, keeping system parameters and environmental parameters the same.

“…It contributes to global warming and environmental pollution. In order to save the environment, renewable energy sources such as wind or photovoltaic panels have been used (Rocio et al, 2018, J. Kern M. Russell 1978. Accelerated growth in electricity demand while reducing the use of fossil fuels has forced the use of renewable energy sources.…”

Automatic position control of the solar cell (APCoSC) is a project of the system, whose task is to direct the surface of the photovoltaic cell perpendicular to the sunrays falling on it and to follow the sun. The main parts are the base and pole, on which the cell is mounted. The base consists of a fixed part that provides a stable mounting on the ground, and a rotating part with mounted motor, which can perform a full 360 * rotation. The mast ends with a handle which, can tilt the solar panel automatically up to 90 degrees vertically by using a motor. The sun position sensor is built of 4 ambient light photosensors (APDS) arranged in the shape of a plus, enclosed in a casing, to which the sun's rays fall through the round opening. The case can be attached directly to the solar cell, or a handle using an adapter, in such a way as to form a parallel plane with the cell. The STM32 microcontroller manages the system and engine operation. The sun position sensor can work at a temperature of -30 to 85 Celsius, which ensures its universal use in many places on the earth. The photovoltaic cell produces the most energy when the sun's rays fall perpendicular to its surface, which is why the automatic tilt adjustment is used. In large cities, APCoSC is used on flat roofs of houses, where there are many obstacles such as other buildings around. The system adapts itself to the position of the sun and selects the most favourable position of the solar panel in real time.
