摘要/Abstract

摘要： 基于电力系统弹性定义及原理,将传统电储能设备与需求响应相结合,提出一种考虑广义储能的电网运行弹性优化方法。根据4种指标来综合评价5种基于拓扑的攻击方案,选取对系统性能最不利的攻击策略以模拟对电力系统的破坏。以系统运行成本最小为目标进行含风力电站、储能机组组合调度。针对灾时容灾阶段提出可改善运行期电网弹性的广义储能调度方法,并建立以系统弹性最大为目标的灾后恢复优化模型,通过遗传算法计算最优恢复策略。以IEEE-30节点系统为算例验证了广义储能改善系统灾后性能并提高电网运行弹性的有效性。

Abstract: Based on the definition and principle of power system resilience, combining the traditional energy storage equipment with the demand response, an optimization method of power system operation resilience considering generalized energy storage is proposed. Five attack schemes based on topology are evaluated according to four indexes, and the most disadvantageous attack strategy is selected to simulate the damage of power system. Taking the minimum operating cost of the system as the objective, a combined scheduling model involving wind power station and energy storage unit is carried out. A generalized energy storage scheduling method is proposed to improve the resilience of power grid in operation period in recovery stage, and an optimal model of disaster recovery is established to maximize the system resilience. The optimal recovery strategy is calculated by genetic algorithm. The IEEE 30-bus system is taken as an example to verify the effectiveness of the generalized energy storage in improving the system performance and the resilience of power grid operation.

Key words: resilient grid, generalized energy storage, power grid attack, recovery strategy
