Each network contains it's bounding box within the convBoundary attribute of the <location> element To shift the reference system to the center, post-process your network with
netconvert -s old.net.xml -o new.net.xml --offset.x halfWidth --offset.y halfHeight where halfWidth is the third entry of convBoundary divided by 2 and halfHeight is the fourth entry divided by 2.
