Comprehensive approach of power system contingency analysis
J. Deuse, Member, IEEE, K. Karoui, Member, IEEE, A. Bihain, J. Dubois
Abstract—Security of supply in power system supposes that the robustness of the system can be guaranteed in case of credible contingencies. This robustness relies on structural rendancy and on security margins. Traditionally, the “-1” contingency analysis has been used for such check. This methodology leads to the definition of “sizing incidents”, or credible contingencies[1]. The system is said “N-1” secure if it remains within its operating domain for these “sizing incidents”. Today some trends exist for relaxing the application of this criterion. This means that some emergency control actions must be implemented in the system for guaranteeing its security. This asks for their representation in the methodological approach used for evaluating the security of supply. This is not possible with traditional tools.
Index Terms—Interconnected power system, instrial power system, load flow analysis, power generation control, reactive power control, voltage control, power system dynamic stability, power system transient stability, static VAR compensator.
I. INTRODUCTION
T HE continuity of service in developed system is certainly the main concern of system operators. For reaching high level performances, electric sector had, until recently, all necessary means at disposal: rigorous planning of the development of the system, integrated management of generation and transmission, investment capacities in concordance with technical objectives agreed between the different components of the society. This favorable situation permitted to maintain power system operation at sufficient distances from its physical limits, with few concerns about what could happen if such limits were overtaken. Very deep incidents, quite rare, revealed often some risks attached to particular deterioration mechanisms, which were previously completely ignored by operators.
Power system unbundling is progressively modifying the conditions for such controlled management of power system security. Indeed, the free access to the interconnected system, bilateral contracts settled between generating companies and consumers make conditions of operation more and more unforeseeable. The quest for the maximum economical efficacy leads to the use of interconnection capacities far above levels expected when they were built.
All these changes lead to the operation of the system nearer to their physical or to their stability limits; this increases the risk of transgression of these limits in case of emergencies

⑹ 谁有关于电力系统方面的英文论文
An electric power system (or simply power system) is a network of electrical components used to supply, transmit and utilise electric power. The quintessential example of an electric power system is the network that supplies a region's homes and instry with power - for sizable regions, this power system is known as the grid and can be broadly divided into the generators that supply the power, the transmission system that carries the power from the generating centres to the load centres and the distribution system that feeds the power to nearby homes and instries. Smaller power systems are also found in instry, hospitals, commercial buildings and homes. The majority of these systems rely upon three-phase AC power - the standard for large-scale power transmission and distribution across the modern world. Specialised power systems that do not always rely upon three-phase AC power are found in aircraft, electric rail systems, ocean liners and automobiles.
