Distribution Storage Networks

Distribution storage networks are interconnected distribution-level bulk energy storage devices that function as core infrastructure elements to provide both grid resilience and defense against IoT-based cyber grid security threats. The recognition that these are core grid functions changes how storage of this type valued, financed, and operated as compared to storage for ancillary grid services. Distribution storage networks make use of fast bilateral storage to buffer the grid from edge device-based volatilities; this is the essence of both its resilience capability and its cyber defense capability. These storage networks must be core grid components because resilience is an intrinsic grid characteristic and both it and cyber defense of the distribution grid are the responsibility of the distribution utility.

As core infrastructure, distribution networks can be treated via least cost/best fit rather than through benefit/cost analysis. Operation of such systems is consonant with standard utility operating and safety practices, control systems, and financial models, thus presenting very little in the way of barriers to adoption, unlike the third party ownership models. In addition, storage deployed in this manner is not just firm-dispatchable, it is also firm-designable, meaning that the utility can place the amount of storage it needs in the locations where it is needed for grid operational purposes at the time that it is needed.
