This study deals with a solar photovoltaic demonstration project composed of four types sub-plants that will be operated in the Saemangeum Seawall coast. The aimed to investigate most efficient sub-plant types. Hydrodynamic analyses were undertaken obtain loads exerted on floating power plants which two kinds frame structures supported shed- and gable-type panels, producing three floaters. inte...

This paper presents a new system configuration for a large-scale Photovoltaic (PV) power system with multi-line transmission/distribution networks. A PV power plant is reconfigured in a way that two adjacent power system networks/ feeders can be interconnected. The inverter modules in a PV power plant are configured such that the system is represented as a back to back inverter connected multi-...

A power system is a nonlinear one. When turbulence occurs in the power system, the stability of the system depends on the initial operating conditions and the nature of the turbulence. Nowadays renewable energy sources including photovoltaic have a key role to meet high demand of modern societies and to maintain voltage of the buses, while they also provide clean electrical energy. However, inc...

The cell has optimum operating point to be able to get maximum power. To obtain Maximum Power from photovoltaic array, photovoltaic power system usually requires Maximum Power Point Tracking (MPPT) controller. This thesis research work will provides a small power photovoltaic control system based on fuzzy control with FPGA technology design and implementation for MPPT. The proposed maximum powe...

The reactive-power service will be or is already obligatory for new grid-connected photovoltaic systems. The paper investigates the impact of the reactive-power service on the energy yield of a photovoltaic system and its effect on the inverter sizing and economic yield. Based on simulations and analysis of an operating photovoltaic system we show that energy losses due to the reactive-power se...

Step-up transformers are used to connect large PV plants to the utility network, their sizing being often accomplished only taking into account the PV plant peak power. However, a largely unpredictable power injection on the main grid is obtained if a too large rated power is selected, leading to grid instabilities. This may result in plant shutdowns, while requiring a remarkable reserve power ...

Solar power and wind are the most promising distributed energy sources. The photovoltaic system has attracted significant attention in recent years. Although their benefits are numerous, they are known to create power quality issues, because of the power electronic converters they use. This paper investigates if there is a possibility to improve power quality only by connecting a solar photovol...
