Power Capability

In a standalone photovoltaic (PV) system, a bidirectional DC converter (BDC) is needed to prevent the battery from damage caused by DC bus voltage variation. In this paper, BDC was applied in a standalone solar PV system to interface the battery with a DC bus in a standalone PV system. Therefore, its bidirectional power capability was focused on improving save battery operation while maintaining high power quality delivery. A non-isolated, buck and boost topology for the BDC configuration was used to interface the battery with the DC bus. PID controller-based control strategy was chosen for easy implementation, high reliability, and high dynamic performance. A simulation was conducted using MATLAB Simulink program. The simulation results show that the implementation of the BDC controller can maintain the DC bus voltage to 100 V, have high efficiency at 99.18% in boost mode and 99.48% in buck mode. To prevent the battery from overcharging condition, the BDC stops the charging process and then works as a voltage regulator to maintain the DC bus voltage at reference value.

Small scale PV systems are mainly used in Distributed Generating systems (DG).The problem with PV DG system is for designing this system high voltage gain need to be required. In order to achieve this high gain we are choosing Grid connected PV system that is large scale Grid connected PV system In Grid connected PV system Power Electronic devices such as converters and inverters are main parts along with PV panels. In our work we have designed a solar PV system with varying irradiation in MATLAB/SIMULINK and enhance its output capacity before its integration with the grid. To design a suitable controller for per phase designed power converter such that it produces better output results than the traditional converter. The controller has to be designed along with buck boost control of DC output from the system instead of designing a whole new and separate control algorithm for inverter. It was concluded that active power output from the system from approximately 1MW in conventional inverter has improved to 12MW in the proposed scheme.

Solar Pv System

In this project, a new system for power supply for remote areas has been proposed. In the proposed system, solar PV based system with battery storage for stand-along application has been discussed. In addition, the use of a multilevel inverter and high-gain DC/DC converter has been proposed. The proposed multilevel inverter generates a nine-level output voltage waveform with quadruple voltage gain. The proposed DC/DC converter is based on the concept of a switched-inductor with voltage lift switched-capacitor and has been verified for a voltage gain of 20. The experimental results confirmation the satisfactory performance for stand-alone applications of the proposed converters.

Power Point

The inexhaustible source of energy which produced from sun through radiation and it is readily available source at free of cost. Solar Photo Voltaic (PV) systems are used as a primary source to produce power. The solar PV system needs DC-DC converter with enhanced voltage gain as well as efficiency. A typical DC-DC converter provides constrained gain and productivity as increase in requirements. For organization of battery Bidirectional converter is used which allows the energy flow in both the direction. The complete working of below voltage PV system and battery that is used are worked by using various dc converters from which the efficiency and gain level can be improved. Maximum Power Point Tracking (MPPT) is employed to receive peak power from solar PV by sustaining DC line voltage and satisfy power requirements. The perturb and observe (P&O) algorithm is mostly used to obtain the high voltage from solar PV. The entire framework is designed and simulated using MATLAB-Simulink toolbox.

A Performance

Sunlight is energy that can be converted into electrical energy. One of the uses is by applying it to the roof ofthe building. The application in this building has restrictions such as the placement of the PV moduleshorizontally and vertically. In the study comparing the results of energy obtained from the PV system withhorizontal and vertical positions with a standard degree angle in the direction of azimuth sunlight. Positionusing the horizontal produces more energy and reaches a performance ratio of more than 80%.
