摘要: 为减弱自然灾害及其他人为因素对电力系统的影响,文章提出了一种考虑可移动式储能与网络重构交互优化的弹性配电网灾后恢复策略。该恢复策略模型以最大化恢复供电负荷量为优化目标。首先,对灾害后的网络进行预估,分析得出形成微电网的个数,并进行网络重构。其次,根据网络重构结果对可移动式储能的接入位置进行优化,其中可移动式储能的移动遵循时间最短的原则;对移动后的配电网进行网络重构直至满足要求。文章所提策略能够在满足孤岛安全运行的基础上,达到最小的失负荷量,最大限度地利用可再生能源,减弱灾害对电力系统的影响,增强配电网的弹性和经济性。最后,以IEEE 33节点系统为例对不同灾害场景进行灾后恢复仿真,验证了所提策略的有效性和实用性。

Abstract:  In order to reduce the impact of natural disasters and other human factors on power system, a post-disaster recovery strategy of resilient distribution network considering the interactive optimization of mobile energy storage system and network reconfiguration is proposed in this paper. Considering the maximization of load recovery, this strategy firstly estimates the network after the disaster, analyzes the number of micro-grid formation, and carries out network reconstruction. Secondly, according to network reconstruction results, the access location of mobile energy storage system is optimized, and the removal of mobile energy storage follows the principle of the shortest time. Finally, a new network reconfiguration of the distribution network is carried out to meet the requirements. The strategy proposed in this paper can minimize the load loss and maximize the use of renewable energy on the basis of security operation of isolated islands. It reduces the impact of disasters on power system and greatly increases the resilience and economy of the distribution network. Finally, this paper takes IEEE 33-node system as an example to simulate disaster recovery in different scenarios, and verifies the effectiveness and practicability of the proposed strategy.
