Single Phase Transformerless Inverter Topologies For Grid-Tied Photovoltaic System: A Review
Single Phase Transformerless Inverter Topologies For Grid-Tied Photovoltaic System: A Review
Faculty of Engineering University of Malaya
Grid-tied inverters are the key components of distributed generation system because of their function as an effective interface between renewable energy sources and utility. Recently, there has been an increasing interest in the use of transformerless inverter for low-voltage single-phase grid-tied photovoltaic (PV) system due to higher efficiency, lower cost, smaller size and weight when compared to the ones with transformer. However, the leakage current issues of transformerless inverter, which depends on the topology structure and modulation scheme, have to be addressed very carefully. This review focuses on the transformerless topologies, which are classified into three basic groups based on …

The production of PV power depends on different meteorological parameters. Accumulation of dust is one of the factor which reduces the output power. The recent study was done in Tripura, India and there is maximum of 13% and minimum of 9% reduction in efficiency has been observed during the period of experiment
Zigbee-Based Data Acquisition System For Online Monitoring Of Grid-Connected Photovoltaic System
Zigbee-Based Data Acquisition System For Online Monitoring Of Grid-Connected Photovoltaic System
Faculty of Engineering University of Malaya
For grid-connected photovoltaic (PV) system, monitoring is considered as a crucial aspect for observing the stability and performance of the system. The simplest method is to have the data collected and transmitted across data cables. Due to the cost and technical limitations of the data cable, the monitoring station needs to be located reasonably close to the monitored plant. Apart being inconvenient, the use of data cable often adds capital and maintenance cost to the system. In this research project, a Zigbee-based wireless monitoring system is developed for online monitoring of a grid-connected photovoltaic system. Parameters like temperature, irradiation, PV …

Photovoltaic energy is used in different applications and especially in water pumping and irrigation in remote areas. However, the performances of a photovoltaic pumping system can be degraded with variations of insolation and in order to maximize the efficiency of the photovoltaic energy system, it is necessary to track the maximum power point of the PV array. Many methods have been developed to determine the maximum power point (MPP). In this paper we present the results of performance optimization of a PV pumping system in Bejaia (Algeria) climate. The pumped water is desired to satisfy the domestic needs of three …

Due to the continuous decrease of the solar cells cost, photovoltaic energy is used in different applications. The most important one is the water pumping system powered by photovoltaic generators. These systems can work with or without storage battery. With the increased use of this application, more attention has been paid to their optimum utilization. Many methods have been developed to determine the maximum power point (MPP). In this paper, to control the DC bus voltage, we apply field oriented control (FOC) strategy to induction motor (IM) supply by a photovoltaic (PV) system. And to maximize the efficiency of the …

Global interest in harnessing renewable energy resources has dramatically increased due to the confluence of several factors. The world cannot continue to relay for long on fossil fuels for its energy requirements. Fossil fuels reserves are limited. In addition, when burnt, these add to global warming, air pollution and acid rain. These systems are non- polluting, don’t deplete the natural resources in the long run. The advantages of using solar energy are the cost reduction of installation in the case of non availability of electric grid, reduction of electricity bill and contribution to the protection of the environments (Clean and …

The electrical energy using renewable hybrids are known, medium-term interest thanks to their flexibility vis-à-vis the primary energy sources. The objective of this work is the study of a hybrid central power, which combines two renewable energy sources (wind, solar) with storage and an emergency generator. The management of different energy sources is ensured by a manager who controls the opening and closing switches, depending on weather conditions (illumination, wind speed).
