This paper presents a newly developed EDC (Economic Dispatching Control) function for Tohoku EPCO's new EMS system. In this new EDC, we can minimize total fuel cost under system security constraints such as "AFC margin considering band width and ramp rate in future band changing schedule" and "power flow constraint considering future maintenance schedule". We formulate EDC problem as "continuous variable (generator output) optimization" under "combinatorial optimization of band schedule". To optimize this problem, Problem Space Search method and interior point QP method are adopted. Test results and the actual operation show that, this new EDC can follow against steep increase and decrease of electric demand cooperating with AFC. This EDC has been operating successfully in Tohoku EPCO since June 2003.
