The main purpose of this paper is to discuss the basic understanding of active and reactive power flows in photovoltaic (PV) based distributed generation injected power system and how these power flows will influence the performance and stability of a power system. the harmonic currents injected into the utility grid may be a serious problem since they could lead to unacceptable levels of wave ...

A solar photovoltaic system produces electricity by converting energy from the sun. By the end of 2016, the global installed solar photovoltaic capacity reached 305 GW. Its growth is impressive in the last years; in fact, it was only equal to 41 GW in 2010. However, Europe has installed only 6.9 GW in 2016 (−1.7 GW in comparison to previous year) and this annual power installed is equal to 9% o...

In this paper three-phase isolated source and non-isolated source cascaded two level inverter (CTLI) topology is used for grid connected photovoltaic (PV) system. The CTLI is one of the widespread topology in multilevel inverter. In this work, both topology isolated source and non-isolated source CTLI system are operated to supply active power with available solar irradiance and to supply react...

The increasing penetration of renewable sources with power-electronic interfaces in power systems is raising technical problems and the overall efficiency of photovoltaic systems can decrease dramatically. In this context, the optimal layout for the photovoltaic system is required. The most adequate strategy to connect the renewable system to the electrical power grid or to supply the end users...

A hybrid Photovoltaic/Thermal (PV/T) solar system integrates photovoltaic and solar thermal technologies into one single solar energy device, with dual generation of electricity and heat energy. The aim of the present study is to evaluate the potential for introduction of the PV/T technology into Northern China. For this purpose, outdoor experiments were conducted on a prototype of a PV/T water...

Hybrid photovoltaic thermal (PV/T) solar system comprises a solar collector which is disposed on photovoltaic solar cells. The disadvantage of a conventional photovoltaic cell is that its performance decreases as the temperature increases. Indeed, part of the solar radiation is converted into electricity and is dissipated as heat, increasing the temperature of the photovoltaic cell with respect...

K-water installed the first domestic 100kW floating photovoltaic system on the water surface of multipurpose dam reservoir in October 2011. Also, it installed a 500kW floating photovoltaic generation facility nearby in October 2012 for commercial power generation. Based on these, it installed a 10kW marine photovoltaic generation facility at Sihwa Lake in October 2013. In this paper, static loa...

In the recent years, the solar energy becomes one of the most important alternative sources of electric energy, so it is important to improve the efficiency and reliability of the photovoltaic (PV) systems. Maximum Power Point Tracking (MPPT) plays an important role in photovoltaic power systems because it maximize the power output from a PV system for a given set of conditions, and therefore m...
