Abstract :
This paper presents an advance stratagem to prevent contingencies and solve the optimal problem of economic and security dispatch. The dispatch takes outage and limitation of technical constraints into account. In order to ensure state steady stability for accidents, preventive control algorithm (PCA) based on the generalized reduced gradient method processing a preventive contingency set jointly. The technique determines the active power dispatch and voltage of each generating unit before contingent condition so as to minimize the energy re-dispatch cost subject to dispatch, network, and security constraints. A secure process is proposed to control the power system and provide operators with emergency suggestions in deregulated market.
