本文提出了一种可能的方法，为城市和郊区配电网的用户提供差异化的可靠性选择。为了根据客户的喜好提供不同的可靠性选项，公用事业公司可以部署分布式发电（DG）、分段开关（常闭开关：NCSs）和tie开关（常开开关：NOSs）。在停电期间，DG作为备用发电机组，可以为有需要的客户提供更高的可靠性。此外，公用事业公司可能需要重新配置网络，以便ncs和NOSs以最佳方式运行，向优先客户提供电力。该问题被表述为一个优化问题，其目标是在保证向优先用户供电的同时最小化公用事业责任。优化是离线执行的，最佳开关组合存储在数据库中，供公用事业实时使用。客户对不间断服务的偏好信息是向公用事业公司的ncs、nos和DG提供投资信号所必需的。本文还表明，只要这些投资的成本低于公用事业公司因无法提供服务而必须支付的责任成本，公用事业公司就会投资于提供差异化的可靠性方案。
This paper proposes a possible approach to providing differentiated reliability options to customers in urban and suburban distribution networks. To offer different reliability options based on customer's preferences, a utility can deploy distributed generation (DG), sectionalizing switches (Normally Closed Switches: NCSs) and tie switches (Normally Open Switches: NOSs). During power outages, DG, as backup generation unit, is a means of providing higher reliability to customers who require it. Furthermore, a utility may need to reconfigure the networks such that NCSs and NOSs operate in an optimal way to deliver power to priority customers. The problem is formulated as an optimization problem with the objective of minimizing utility liability while assuring the supply of power to priority customers. The optimization is performed off-line and the optimal switch combinations are stored in a database for use by the utility in real time. The information about customer preferences for uninterrupted service is needed to provide investment signals for NCSs, NOSs, and DG to utilities. The paper also demonstrates that utilities would invest in providing differentiated reliability options as long as the cost of these investments is lower than the liability cost utilities must pay for failing to deliver service.
