Optimized filter for battery energy storage on alternate energy systems

摘要

A system for operating a power generation system 100 within a battery storage/discharge mode includes a power convertor 162 having a DC link 126, 136, a switching module 142 coupled to the DC link, a storage device 144, and a filter coupled between the storage device 144 and power converter 162. The filter may correspond to a normal mode filter configured to limit normal mode voltage from being applied to the storage device 144. A common mode filter may be associated with the storage device 144. The storage device 144 may correspond to one or more batteries 143 while the power generation system 100 may correspond to a wind-driven generator 120.
