目前的英国配电网规划标准，工程建议P.2/6 (P2/6)，定义了在第一和第二回路停电条件下可接受的供电中断持续时间，作为群体需求的函数。此外，P2/6还规定了分布式发电（DG）的容量值，用于将来的电路容量规划。该方法不考虑配电网的其他要素。本文分析了在负荷增长驱动下，采用DSR延迟电网升级时配电系统的可靠性性能。该分析使用了作为低碳伦敦项目一部分执行的试验中的实际DSR性能数据。使用概率风险建模框架评估DSR对供应安全的贡献，以进一步了解以下主题：(i)网络环境下DSR技术的可靠性贡献，（ii） P2/6在估计供应安全贡献方面的优势和弱点，（iii）合同冗余的好处，（iv）交付中DSR巧合（共模故障）对安全贡献的影响。(v) DSR的规模和量级对供应安全贡献的影响。
The present UK distribution network planning standard, Engineering Recommendation P.2/6 (P2/6), defines the acceptable durations of supply outages following first and second circuit outage conditions as function of group demand. In addition, P2/6 specifies a capacity value for distributed generation (DG) to be used in future circuit capacity planning. The approach does not consider other elements of the distribution network. This paper analyses the reliability performance of distribution system when DSR is used to defer network upgrades driven by load growth. The analysis uses actual DSR performance data from trials that were executed as part of the Low Carbon London project. The DSR contribution to security of supply is assessed using a probabilistic risk modelling framework to further inform a number of topics (i) reliability contribution of DSR technologies in a network context, (ii) strengths and weaknesses of P2/6 in estimating contribution to security of supply, (iii) benefits of contractual redundancy, (iv) impact of DSR coincidence in delivery (common mode failures) on contribution to security, and (v) impact of DSR scale and magnitude on contribution to security of supply.
