School of Electrical Engineering, VIT University. Vellore – 632014. Tamilnadu. India In this paper, we present a novel maximum power point tracking method for a photovoltaic system consisting of a photovoltaic panel with a power electronic converter; the whole is feeding a battery. This maximum power point depends on the temperature and irradiation conditions. A robust control using a PI regula...
Renewable energy sources and in particular Photovoltaic (PV) system are implemented in large scale in many countries for power generation. The characteristics of PV arrays are non-linear i.e., the change in temperature and irradiation levels results in change of power generated by the PV arrays. DC-DC converters are connected between the PV system and the load as power conditioning unit to regu...
The test, construction and design of an electronic system in order to measure the electrical characteristic curves of the photovoltaic (PV) module is reported, this electronic system reflects toward the PV module a variable resistance, sampling and capturing the PV module current and voltage, after using software the current and voltage signals are process in order to determinate the power, and...
Electrical efficiency can be increased by combining photovoltaic (PV) and the thermoelectric (TE) systems. However, a simple and cursory combination is unsuitable because the negative impact of temperature on PV may be greater than its positive impact on TE. This study analyzed the primary constraint conditions based on the hybrid system model consisting of a PV and a TE generator (TEG), which ...
As the world strives towards finding alternative sources of power generation, photovoltaic generation has become an increasingly prevalent alternative energy source on power systems worldwide. This paper studies the effects that incorporating photovoltaic generation has on the existing power systems and their power system protection schemes. Along with the addition of this emerging alternative ...
This paper presents a detailed analysis for determining the impact of adding large three phase photovoltaic (PV) systems in secondary (building) power distribution networks. The analysis highlights the protection relay coordination problems arising due to the increase in network fault levels caused due to the contribution from PV generators. A typical distribution network for power supply to la...
In this paper, we analyze the potential for solar photovoltaics (PV) to be deployed on a very large scale and provide a large fraction of a system’s electricity. We explicitly examine how the hourly availability of PV interacts with the limited flexibility of traditional electricity generation plants. We find that under high penetration levels and existing grid-operation procedures and rules, t...
Photovoltaic based reverse osmosis desalination systems (PV/RO) present an effective method of water desalination especially in remote areas. The increase of the feed water temperature leads to an amelioration of the plant performances. Photovoltaic Thermal Collector (PV/T) represents an ideal power source as it provides both electric and thermal energies for the reverse osmosis process. Nevert...
This paper presents the dynamic simulation model to characterize water pumping and heating installation using PV/Thermal panel (PV/T) is developed. The model consists of a set of mathematical equations governing the main components of the system; namely: transparent cover, solar cell, absorber plate and operating fluid. The model is based on the analysis of the energy balance which includes the...
This paper presents 200 KW three phase standalone photovoltaic systems supplying pumping station consist of four pumps 40 KW rating. The system utilizes a two stage energy conversion power conditioning unit topology composed of a DC-DC boost converter and three level-three phase voltage source inverter (VSI). The Boost converter in this paper is designed to operate in continuous mode and contro...
