Research on Self-healing Control of Smart Grid Based on Multi-agent System Consistency

自愈控制能够使智能电网运行中出现的安全隐患得到及时发现和有效解决,进而保障电网稳定、可靠运行。多智能体系统(MAS)是基于人工智能、互联网技术和一致性算法,将若干个智能体连接起来形成的复合体系,可弥补单个智能体存在的运算速度慢、处理能力差等缺陷,进一步提高了电网自愈控制的智能化水平。本文首先介绍了智能电网自愈运行状态的转换和自愈控制系统的组成,随后基于故障自愈要求,给出常用的几种自愈方法。并通过仿真实验,对基于多智能体一致性的自愈控制功能实现效果进行验证,结果表明能够在故障发生后快速响应并通过自愈控制恢复稳定运行,达到了理想预期。

Self-healing control can timely discover and effectively solve the hidden dangers in the operation of smart power grid, thus ensuring the stable and reliable operation of power grid. Multi-agent system(MAS) is a composite system based on artificial intelligence, Internet technology and consistency algorithm, which connects several agents to form a composite system. It can make up for the shortcomings of a single agent, such as slow computing speed and poor processing ability, and further improve the intelligent level of power grid self-healing control. This paper first introduces the transformation of smart grid self-healing operation state and the composition of self-healing control system, and then gives several commonly used self-healing methods based on the requirements of fault self-healing. Simulation experiments were carried out to verify the realization effect of the self-healing control function based on the consistency of multi-agent. The results show that the self-healing control can quickly respond to the failure and restore the stable operation, which achieves the ideal expectation.
