摘要:

为了降低高比例光伏接入对供电电能质量的影响和提高极端灾害发生时的供电保障能力,更具灵活性和经济性的移动储能是提升配电网抗灾能力的有效措施之一。根据高比例光伏接入场景下配电网在灾害发生后对移动储能的需求,构建了计及经济性、脆弱性和移动储能容量3个方面的移动储能配置多目标优化模型,并在极端灾害场景下提出了基于可分离移动储能初始位置布置和应急响应调度的两阶段弹性提升优化调度模型,通过调度控制可分离移动储能的接入位置和充放电功率,实现极端灾害下的供电应急恢复,并提高移动储能在平时和灾时的复用价值,最后通过算例验证了所提方法的有效性。

Abstract:

To mitigate the impact of high-penetration photovoltaic (PV) integration on power quality and enhance the reliability of power supply under extreme disasters, mobile energy storage (MES) with its greater flexibility and cost-effectiveness has been identified as one of the effective measures to improve the disaster resistance of distribution networks. This paper proposes a multi-objective optimization model for determining the configuration of MES under high-penetration PV integration scenarios, considering three key aspects including economic efficiency, vulnerability and MES capacity. Additionally, a two-stage resilience-enhancing optimization and scheduling model is developed for extreme disaster scenarios, which incorporates the initial deployment of separable MES and their emergency response dispatch. By dynamically scheduling the access locations and charge-discharge power of the separable MES, the proposed method ensures emergency power restoration under extreme disasters while maximizing the reuse value of MES during both normal and disaster conditions. Finally, case studies validate the effectiveness of the proposed method.

Key words: mobile energy storage, configuration, pre-deployment, fault recovery, resilience and disaster resistance enhancement
