Abstract:It is very important for an interconnected power system under the m arketing circumstance to quantitatively analyze its stability on- line for tracking the actual operation condition and make decision for stability control adaptively.Preventive control and emergency control have been studied separately till now.In this paper,coordination between them is form ulated as a nonlinear hybrid programm ing on logic- difference- differential- algebraic equations with m any constraints including stability. The objective function is the sum of the daily cost for preventive control and the probabilistic cost for em ergency control. An optimization procedure is proposed for the coordination,which integrates the unique EEAC technique for quantitative analysis of stability and a hybrid programm ing for non- convex nonlinear optim ization. This procedure refreshes the decision table in a sub- real- time fashion.
Keywords:power systems  preventive control  em ergency control  logic- difference- differential- algebraic equations  optimization
