In General, the dispersed power supply system is possible to be robust and small compare with centralized power system. In the satellite system, we aim to downsize the power supply system by using the dispersed power system and cooperative control, which is constructed by solar panel and some bi-directional DCDC converters. In this paper, we describe the evaluation results for the behavior of the...
This paper presents a mathematical analysis of a medium scale Photovoltaic (PV) power generation system connected to the distribution network and of its control system, in which the conversion stage is unique thanks to the absence of a boost chopper. Boost choppers are usually used as actuator for maximum power point tracking (MPPT). The conducted analysis leads to the conclusion that the used inverter...
A high-frequency photovoltaic pulse charger (PV-PC) for lead-acid battery (LAB) guided by a power-increment-aided incremental-conductance maximum power point tracking (PI-INC MPPT) is proposed. The PV-PC implemented by a boost current converter (BCC) is to eliminate sulfating crystallization on the electrode plates of the LAB and to prolong the battery life. The BCC associated with the PV module is...
The distributed flexible network PV (photovoltaic) system is a kind of dc micro-grid which is composed of several PV generation systems, a battery bank and loads. Controller of each converter takes local information and control the converter autonomously. However, there are several problems like voltage rise in dc link causing loss of maximum power control by sudden change of circumstances like as...
In this study, simulation of the single phase grid interactive photovoltaic system is proposed. The proposed system consists of a maximum power point tracking boost converter and a grid interactive voltage source inverter. Interval type-2 fuzzy logic controller is used to track the maximum power point of photovoltaic arrays. Photovoltaic supplied DC electric energy is inverted to AC and imported to...
We propose a boost converter for a stand-alone power supply system using single photovoltaic cell with maximum power point tracking based on two strategies.: ultra-low voltage input, operating energy of the boost converter powered by own output. It realized by discrete parts and low power consumption MCU. The boost converter starts at less than 0.4 V. It also starts at 88W/m2 of sunlight radiation...
The DC distribution in the multisource systems seems to be a reasonable solution because the supplied energy is in the DC form for several sources, such as the photovoltaic panels (PV), the batteries, and the Ultracapacitors. Additionally, the major parts of the used electronics devises in the buildings operate with the DC current, such as computers, air conditioning, and multimedia. Based on these...
This paper proposes the speed sensorless fuzzy MPPT control of grid-connected PMSG for wind power generation. The proposed fuzzy MPPT control is simple since it does not need any knowledge of wind turbine characteristics and speed sensor. Based on small wind power generation, the boost chopper is used to implement the proposed fuzzy MPPT control. There is a specific value of duty cycle which yields...
In this paper, we propose a thermoelectric power generation system with highly efficient ultra low input boost converter having MPPT. The proposed converter starts at input voltage of less than 0.5V and is useful for the thermoelectric power generation system. MPPT is also effective for this system and its tracking efficiency is nearly 100 %. The proposed system effectively draws the power from thermal...
