论文摘要
电能系统正在发生重大变化，以提高系统可靠性并适应不断增长的功率需求。分布式能源资源（DER）的渗透包括屋顶太阳能电池板，储能，电动汽车等，可实现现场生成经济上的可派遣的电力，从而减少运营成本。 DER的有效控制需要实用程序与DER系统运营商之间的通信。用于DER管理和控制的通信协议缺乏复杂的网络安全功能，如果向DERS发出恶意控制命令，则可以损害电源系统的安全操作。为了克服与身份验证相关的协议问题，我们提出了可以在分布式网络协议v3（DNP3）上实现的螺栓安全性扩展。我们将身份验证框架（即Derauth）移植到DNP3中，并利用模拟的DER电池存储系统中的实时测量来增强通信安全性。我们使用DNP3 Master和Outstation设备在测试床设置中评估了我们的框架，并利用DER的熵来执行安全身份验证。
Electric energy systems are undergoing significant changes to improve system reliability and accommodate increasing power demands. The penetration of distributed energy resources (DERs) including roof-top solar panels, energy storage, electric vehicles, etc., enables the on-site generation of economically dispatchable power curtailing operational costs. The effective control of DERs requires communication between utilities and DER system operators. The communication protocols employed for DER management and control lack sophisticated cybersecurity features and can compromise power systems secure operation if malicious control commands are issued to DERs. To overcome authentication-related protocol issues, we present a bolt-on security extension that can be implemented on Distributed Network Protocol v3 (DNP3). We port an authentication framework, DERauth, into DNP3, and utilize real-time measurements from a simulated DER battery energy storage system to enhance communication security. We evaluate our framework in a testbed setup using DNP3 master and outstation devices performing secure authentication by leveraging the entropy of DERs.
