Non-utility owned distributed energy resources (DERs) are mostly untapped currently, but they can provide many grid services such as voltage regulation and service restoration, if properly controlled, and can improve the distribution system's reliability when coordinated with utility-owned assets such as self-healing control and microgrids. This paper integrates transactive energy control into the distribution system reliability evaluation to quantitatively assess the impact of non-utility owned DERs on reliability improvement. A transactive reactive power control strategy is designed to incentivize the DERs to provide reactive power support for improving voltage profiles thus enabling additional customer load restoration during an outage. Also, an operational sequence to coordinate the non-utility owned DERs with the utility owned self-healing control and utility owned microgrids is designed and integrated into the service restoration process with the operational constraints guaranteed by checking the three-phase unbalanced power flow for post-fault network reconfiguration. The reliability indices are then calculated through a Monte Carlo simulation. The transactive reactive power control strategy is tested on a four-feeder distribution system operated by Duke Energy in the U.S. Results demonstrate that the non-utility owned DERs with the transactive control improve the reliability of both the system and critical loads by more than 30%.

将无功能量集成到具有微电网的自愈配电系统的可靠性评估中

非公用事业拥有的分布式能源（DER）目前大多尚未开发，但如果控制得当，它们可以提供许多电网服务，例如电压调节和服务恢复，并且与公用事业拥有的资产（例如自愈控制和微电网。本文将交互能源控制集成到配电系统可靠性评估中，以定量评估非公用事业拥有的分布式能源对可靠性改进的影响。交互无功功率控制策略旨在激励 DER 提供无功功率支持以改善电压分布，从而在停电期间实现额外的客户负载恢复。还，通过检查故障后的三相不平衡潮流来保证运行约束，以协调非公用事业拥有的 DER 与公用事业拥有的自愈控制和公用事业拥有的微电网的操作序列被设计并集成到服务恢复过程中网络重新配置。然后通过蒙特卡罗模拟计算可靠性指标。交互无功功率控制策略在美国杜克能源公司运营的四馈线配电系统上进行测试 结果表明，具有交互控制的非公用事业公司拥有的分布式能源将系统和关键负载的可靠性提高了 30% 以上.
