随着电网纳入越来越多的分布式能源（DER），提供新一代能源，为改善电网的运行创造了新的机会，同时也为保持电网的可靠性和安全性带来了巨大的挑战。为了提高电网性能，可利用分布式电源提供重要的支持功能，例如支持频率和电压水平，特别是如果它们作为高级配电管理系统（ADMS）的一部分得到通信方案的辅助。不幸的是，这种连接和电网支持功能也带来了额外的网络安全风险，可能会导致电网服务的退化，特别是在大量分布式发电的情况下。本文将首先讨论DERs支持系统和互操作性目标所需的通信，以及保护这些通信的安全要求和影响。讨论了与分布式交换机相关的一些常见安全机制，并使用了一个模拟的15总线配电馈线模型来演示分布式交换机通信的各个方面及其对电网性能的影响。这些结果有助于增进对安全实现DER通信的好处、需求和机制的理解，同时确保维护电网的可靠性。
As the power grid incorporates increasing amounts of distributed energy resources (DER) that provide new generation sources, new opportunities are created for improving operation of the grid while large challenges also arise for preserving grid reliability and security. To improve grid performance, DERs can be utilized to provide important support functionality, such as supporting frequency and voltage levels, especially if they are assisted by communication schemes as part of an advanced distribution management system (ADMS). Unfortunately, such connectivity and grid support functionality also creates additional cyber security risk with the potential for degradation of grid services, especially under conditions with high amounts of distributed generation. This paper will first discuss the communications needed by DERs to support system and interoperability objectives, as well as the security requirements and impact of securing these communications. Some common security mechanisms are discussed in relation to DERs, and a simulated 15-bus model of a distribution feeder is used to demonstrate aspects of the DER communications and impact to grid performance. These results help to advance understanding of the benefits, requirements, and mechanisms for securely implementing DER communications while ensuring that grid reliability is maintained.
