Series-Connected Adaptive Stabilizer for the Grid Connected Inverter at Weak Grid
2018 Asian Conference on Energy, Power and Transportation Electrification (ACEPT), 2018This paper proposes a series-connected adaptive stabilizer (SAS) to fix the instability problem between the grid-connected inverter (GCI) and the weak grid via shaping the grid impedance. Different from the traditional stabilization method, the SAS does not need to know the information about the GCI, therefore, it can be treated as a module ...

A single-phase grid-connected PV inverter with improved grid-connected current
The 27th Chinese Control and Decision Conference (2015 CCDC), 2015This paper presents an effective method, which can address the existing dc-link double-line-frequency voltage ripples in single-phase grid-connected PV inverters, to improve the grid-connected current. The instantaneous power pulsations at grid side cause double-line-frequency fluctuations of the dc-link voltage in single-phase grid-connected PV ...

Development of grid-connected inverters for micro-grid
2014 Clemson University Power Systems Conference, 2014As an important part of the smart grid, the micro-grid contains distributed energy sources, loads, and control devices. An energy storage system and a doubly fed induction generator based wind turbine associated with an ultracapacitor are the main micro grid sources in this paper.

IEE Colloquium on Developments in Photovoltaic Electricity Production, 1997
The large central station PV system feeding power into the utility grid was the vision of the early pioneers in photovoltaics. It is still the "holy grail" sought by much of the PV industry. Here, the author describes, however, that there are two grid-connected markets which are much closer to being real market opportunities-embedded generation and ...

Grid-connected photovoltaic systems for grid voltage correction
2014 15th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA), 2014Researchers have invented recently the grid-connected photovoltaic systems to compensate for the power consumption of loads connected to grid either partially or totally. In this paper, grid-connected photovoltaic systems are used also to solve the electric grid problems, specifically any disturbance in amplitude of the grid voltage at the point of ...
