In circumstance around electric power system, we
have subjects on slow down of increasing electric power
demand, cost down, deregulation and so on. Then at
a glance, we have no promotion of introducing SCG
in power system. However, SCG, which is cheap, of
high efficiency and of good performance in power system, has utility values and will be introduced in power
system. For examples, in power system which has a
lot of IPPs to be introduced as deregulation, SCG
has very powerful for voltage stability and system stability with little controls. SCG is considered to be useful for solving problems appeared in future power
system.
