主　　题：Operational reliability Restructured power system Wind power Simulation 

摘      要：In the last two decades,the wind power generation has been rapidly and widely developed in many regions and countries for tackling the problems of environmental pollution and sustainability of energy ***,the high share of intermittent and fluctuating wind power production has also increased the burden of system operator for securing power system reliability during the operational ***,the power system restructuring and deregulation have not only introduced the competition for reducing cost but also changed the strategy of reliability evaluation and management of power *** conventional long-term reliability evaluation techniques have been well developed,which have been more focused on planning and expansion rather than operation of power *** paper proposes a new technique for evaluating operational reliabilities of restructured power systems with high wind power *** proposed technique is based on the combination of the reliability network equivalent and time-sequential simulation *** operational reliability network equivalents are developed to represent reliability models of wind farms,conventional generation and reserve provides,fast reserve providers and transmission network in restructured power systems.A contingency management schema for real time operation considering its coupling with the dayahead market is *** time-sequential Monte Carlo simulation is used to model the chronological characteristics of corresponding reliability network *** method is also developed in the simulation procedures for improving the computational *** proposed technique can be used to evaluate customers’reliabilities considering high penetration of wind power during the power system operation in the deregulated environment.
