电力系统潮流调整须针对越限等问题动态修正控制变量,而结果判断和数据调整工作高度依赖人工且专家经验难以量化推广。大语言模型(LLM)技术快速迭代进步,由LLM驱动的智能体框架在处理复杂任务和实现自动化决策方面展现出强大的适应性、灵活性和鲁棒性。文中提出了一种基于LLM的电力系统潮流自适应计算调整方法,利用LLM的推理能力增强策略调整的适应性,调用潮流计算模块实时验证策略可行性,构建了动态感知、自主决策与持续优化的闭环工作流。在计算调整过程中引入检索增强生成技术以提供安全运行约束与辅助决策支持,实现了复杂约束下潮流计算及调整的全流程自动化。在IEEE 30节点和IEEE 118节点系统的算例分析验证了LLM在电力系统自动化计算分析方面的应用潜力。
Power flow adjustment in power systems requires dynamic correction of control variables in response to problems such as limit violations. However
result judgment and data adjustment rely heavily on manual work
and expert experience is difficult to quantify and generalize. With the rapid iteration and advancement of large language model (LLM) technology
LLM-driven agent frameworks have demonstrated strong adaptability
flexibility
and robustness in handling complex tasks and realizing automated decision-making. This paper proposes an adaptive calculation and adjustment method for power flow in power systems based on LLMs. The reasoning capability of LLM is used to enhance the adaptability of strategy adjustment
and the power flow calculation module is invoked to verify the feasibility of strategies in real time
forming a closed-loop workflow with dynamic perception
autonomous decision-making
and continuous optimization. Retrieval augmented generation is introduced during the calculation and adjustment process to provide safe operation constraints and auxiliary decision-making support
realizing the full-process automation of power flow calculation and adjustment under complex constraints. Case studies on the IEEE 30-bus and IEEE 118-bus systems verify the application potential of LLM in the automated calculation and analysis of power systems.
