由于配电部门固有的大量故障,配电公司负责达到一个可接受的可靠性指标;否则,他们将面临投诉.因此,监管机构通常有义务对网络的可靠性改进进行投资,但对可靠性的投资通常是从配电公司的角度出发的,而与顾客满意度无关.一方面,用户对配电中断的敏感性是不相同的,若只提高网络的可靠性,而没有考虑到负载的重要程度和可靠性要求的差异;另一方面,配电公司试图尽可能地降低投资成本.本文从资产管理策略的角度,介绍了一种新的联合交换机配置方法,它可以降低交换机的成本.为此,在不同类型的策略中进行了两种开关布局规划,以比较它们的结果.首先,在减少系统未提供的总能量(ENS)的基础上执行开关控制.然后,通过修改策略,从配电公司的角度进行模糊开关布局,只考虑最敏感于被称为重要或临界负荷的中断的负载点的总数.此外,通过满足相关约束,忽视低敏感用户的可靠性.这是一种基于负荷重要性的规划,它可以相对于以往策略实现的切换成本降低,并意味着与可靠性和相应约束相关的风险管理.在模糊网络环境下,采用模糊方法和新的切换机制来建模和控制与临界负荷相关的风险,并对系统的风险进行建模和控制.%Since distribution sector is inherent into high amount of failures, distribution companies (DISCOs) are responsible of attaining an acceptable value for the reliability indices and otherwise they will face up to complaints. So they are usually obligated by regulators to invest on reliability improvement of network. But this investment on reliability is usually from the DISCO's viewpoint and is also irrespective of customer satisfaction level. In other words, customers are not at the same level of sensitivity to interruptions but DISCO improves the reliability of network without considering the differences in importance degree of loads and their level of reliability requirement. On the other hand DISCOs attempt to reduce their investment costs as much as possible. This paper introduces a novel approach in the field of joint switch placement that can reduce the switch cost from the perspective of asset management policies. To this end, two switch placement plannings in different types of strategies are performed to compare their results. Firstly as witch placement is performed based on reducing the total energy not supplied (ENS) of the system. Then by revising the strategy, a fuzzy switch placement is performed from the DISCO's point of view which just considers the total ENS of load points most sensitive to interruptions known as important or critical loads. Furthermore, by meeting the related constraints, the reliability of low sensitive customers is disregarded. This is a load importance based planning which can result in switch cost reduction relative to the amount achieved in previous strategy and implies the management of risks associated with reliability and respective constraint. Fuzzy method and new switching mechanism in fuzzy environment of network are implemented to modeling and controlling the risks associated to ENS of critical loads and also the ENS of system.
