Statistical analysis and dimensioning of a wind farm energy storage system

Analysis and simulation of dynamic performance for DFIG-based wind farm connected to a distrubition system

Local renewable resources such as wind and solar are often available in remote locations. Wind farms consist of many individual wind turbines which are connected to the electric power transm­iss­i­o­n ne­tw­o­r­k­. A wind farm can use the wind resources from a certain area efficiently. Double-fed induction generator (DFIG) is a gene­rating principle widely used in wind turbine (WT). DFIG are ab...

Energy Storage for a Stand-alone Wind Energy Conversion System

This paper deals with a wind-based stand-alone generating unit with Permanent Magnet Synchronous Generator (PMSG) and a Lead Acid Battery (LAB) for energy storage, during wind speed variation as well as transient performance under variable load. The main purpose is to supply 230 V/50 Hz domestic appliances through a single-phase inverter. Simulations and experimental results validate the stabil...

Electrical Energy Storage System for Wind Turbines

Energy storage devices and solutions are required for power quality and balance within wind systems. In the context of rapidly expanding of distributed energy sources, the wind energy converters are in the center of interest. In this case, the direct dependence of the power generation capability for a given wind speed represents a major problem of wind energy conversion with regard to large-sca...
