Introduction Economic dispatch is the main function of EMS To some extents,it is the generation plan, including unit commitment,hydro-thermal plan,exchange plan,repair plan and fuel plan. According to the period:short-term plan,i.e., AGC,short generation plan (in a day or a week);mid-term plan,one month to one year; long-term plan,several to tens of years, including the development plan of power sources and power grid 电力拿镜广城洲量写控制四川省童点实验蜜 家电网
