| 摘要: |
| 针对当前极端灾害场景对于电力系统频率安全考虑不足的问题，提出了台风灾害下考虑系统频率安全的多种灵活性资源协同弹性规划模型。基于Batts台风风场和线路故障率模型确定台风灾害下考虑连锁故障演化流程，获取系统的故障场景。分析台风灾害引发的各种扰动，构建灵活性资源参与调频的动态频率响应模型，基于transformer的符号回归获取频率安全约束的显示表达式，并将其嵌入规划模型。在路网耦合的背景下，构建考虑各种灵活性资源的灾前规划和灾中灾后动态调度的两阶段鲁棒弹性规划模型框架。在IEEE 39节点系统上进行算例仿真，分析台风灾害下考虑频率安全约束的有效性，验证了构建的弹性规划模型能够有效减少负荷损失和系统频率波动。 |

| Abstract: |
| To address the issue of insufficient consideration of frequency security in power system under extreme disaster scenarios, a collaborative resilience planning model of multiple flexible resources conside-ring system frequency security under typhoon disaster is proposed. Based on the Batts typhoon wind field and line fault rate model, the process of cascading failure evolution under typhoon disasters is determined to obtain system fault scenarios. Various disturbances caused by typhoon disasters are analyzed, and a dynamic frequency response model involving flexible resources in frequency regulation is constructed. Using transformer-based symbolic regression, an explicit expression for frequency security constraints is derived and embedded into the planning model. Then, in the context of road network coupling, a two-stage robust resi-lience planning model framework is established, incorporating pre-disaster planning and dynamic scheduling during and after the disaster with various flexibility resources. Simulation case studies of the IEEE 39-bus system are conducted to analyze the effectiveness of the frequency security constraints under typhoon disasters, verifying that the proposed resilience planning model can effectively reduce load loss and system frequency fluctuations. |
