正如第一章所讨论的，电力系统的基本功能是尽可能经济地满足系统负荷和能量需求，并合理保证连续性和质量[1]。相对低成本的电能和高可靠性的两个方面经常发生直接冲突，给电力系统管理者、规划者和运营商带来了一系列具有挑战性的问题。电力公司还面临着越来越多的不确定性，涉及其运营和规划未来系统的经济、政治、社会和环境限制。这对新设施的广泛合理性提出了越来越高的要求，并更加重视系统成本和可靠性的优化。资本和运营资源分配的整体问题中的一个组成部分是可靠性成本和可靠性价值的评估[2]。评估与提供可靠服务相关的成本的能力已相当成熟并被接受[3, 4]。相比之下，评估提供可靠服务的价值的能力尚未得到很好的建立，并且在这些方法被认为完全可以接受之前需要进行大量的工作。确定服务可靠性的价值是一项困难且主观的任务，因为直接评估目前似乎不可行。一种正在被广泛使用的实用替代方案是评估由于电力供应故障而给客户带来的影响和金钱损失。
As discussed in Chapter 1, the basic function of an electric power system is to satisfy the system load and energy requirements as economically as possible and with a reasonable assurance of continuity and quality [1]. The two aspects of relatively low cost electrical energy at a high level of reliability are often in direct conflict and present power system managers, planners, and operators with a wide range of challenging problems. Electric power utilities are also facing increasing uncertainty regarding the economic, political, societal, and environmental constraints under which they operate and plan their future systems. This has created increasing requirements for extensive justification of new facilities and increased emphasis on the optimization of system costs and reliability. An integral element in the overall problem of allocating capital and operating resources is the assessment of reliability cost and reliability worth [2]. The ability to assess the costs associated with providing reliable service is reasonably well established and accepted [3, 4]. In contrast, the ability to assess the worth of providing reliable service is not well established and considerable work will be required before these methodologies can be considered to be completely acceptable. Establishing the worth of service reliability is a difficult and subjective task, as direct evaluation does not appear to be feasible at this time. A practical alternative, which is being widely utilized, is to evaluate the impacts and the monetary losses incurred by customers due to electric power supply failures.
