摘要
随着分布式能源在配电网中所占比重的增高,包含多个分布式发电单元的多微网系统(multi-microgrid system,MMS)受到人们的广泛关注。为降低铺设、布线和维护成本,MMS倾向于采用无线通信技术来实现其运行、控制及保护等关键功能,而这必然加大信息传输的风险,但目前对MMS的研究主要围绕物理控制防护展开。为此结合密码学技术,对MMS的安全能量路由机制进行了深入研究。首先分析了MMS面临的信息安全问题,指出其在完整性、可用性和机密性方面的安全风险。然后基于Io Ius框架和逻辑密钥层次结构,分别从微网和大电网发出能量请求两方面设计了其安全能量路由机制。最后针对能量路由机制的密钥管理问题,设计了相应的密钥管理方案。方案分析结果表明了所提机制的可行性。
With increasing proportion of distributed energy sources in distribution network, multi-microgrid system（MMS） including a lot of distributed generation units attracts more and more attention. In order to reduce cost of laying, wiring and maintenance operations, MMS tends to adopt wireless communication technologies to realize key functions such as operation, control and protection.This increases information transmission risks inevitably. But so far main research focus for MMS is on its physical control and protection. Combined with cryptography techniques, an in-depth research on secure energy routing mechanism for MMS is conducted. Firstly, this paper analyzes MMS information security issues and its security vulnerabilities in integrity, availability and confidentiality. Secondly, a secure energy routing mechanism for both macro-grid and micro-grid as energy applicants is designed based on Iolus framework and logical key hierarchy scheme. Finally, key management scheme is designed for the proposed energy routing mechanism, and a feasibility analysis is performed.
