Penetration of distributed energy resources (DERs) is rapidly increasing in the bulk power system (BPS); they are growing to be a significant portion of generation. As such, grid-support capabilities are being developed and implemented; IEEE Std. 1547 mandates new interconnection and interoperability standards to achieve these capabilities and allow remote users to change behaviors to many devices. However, as their presence increases, the impact of DERs on the BPS also increases. Therefore, if a disturbance occurs in the DER system, its effects could propagate throughout the BPS. These disturbances could range from equipment malfunctions to resource variability to cyber attacks. This document will discuss general requirements needed for developing a distributed cryptography module for implementation in DER systems. First, we will examine the composition of DER systems in Section 2. Procedures to identify critical assets and the security of DERs is discussed in Section 3. Section 4 introduces cryptography concepts and Section 5 discusses implementation needs and options. Finally, practical considerations are provided in Section 6 and conclusions are provided in Section 7.
