The output power from renewable energy sources fluctuates because of weather variations. This paper proposes an effective power quality control strategy of renewable energy sources connected to power system using photovoltaic (PV) array and supercapacitor. A supercapacitor is connected to the DC bus of PV power generation system for power quality control of the grid-connected renewable energy sources...
This paper describes a design of grid-simulator for an experiment of transient stability of grid-connected renewable energy system. A transient analysis of renewable energy system has been researched by a simulation, because a direct connection of renewable energy system to the real utility under transient grid conditions is dangerous and it is hard to produce the transient grid conditions with direct...
An unintentional islanding may result in personnel and equipment safety hazards. In order to detect the islanding, an anti-islanding method for the photovoltaic power generation and active filter (PV-AF) system was proposed by the authors. However, when multiple PV systems are connected to the same distribution line, the detection of islanding is more difficult than the single PV system is connected...
This paper deals with harmonics and reactive power compensation method by grid-connected Photovoltaic (PV) generation system. The experiment is carried out on the proposed single-stage grid-connected PV generation system, and controlled by digital signal processor TMS320F2812. The experimental results include converter operating features either as active power filter or static synchronous compensator...
