This paper presents a user-friendly design method for accurately sizing the distributed energy resources of a stand-alone microgrid to meet the critical load demands of a military, commercial, industrial, or residential facility when the utility power is not available. The microgrid combines renewable resources such as photovoltaics (PV) with an energy storage system to increase energy security for facilities with critical loads. The design tool's novelty includes compliance with IEEE standards 1562 and 1013 and addresses resilience, which is not taken into account in existing design methods. Several case studies, simulated with a physics-based model, validate the proposed design method. Additionally, the design and the simulations were validated by 24-hour laboratory experiments conducted on a microgrid assembled using commercial off the shelf components.

Sticky notes are ubiquitous in design processes because of their tangibility and ease of use. Yet, they have well-known limitations in professional design processes, as documentation and distribution are cumbersome at best. This paper compares the use of sticky notes in ideation with a remediated digital sticky notes setup. The paper contributes with a nuanced understanding of what happens when remediating a physical design tool into digital space, by emphasizing focus shifts and breakdowns caused by the technology, but also benefits and promises inherent in the digital media. Despite users' preference for creating physical notes, handling digital notes on boards was easier and the potential of proper documentation make the digital setup a possible alternative. While the analogy in our remediation supported a transfer of learned handling, the users' experiences across technological setups impact their use and understanding, yielding new concerns regarding cross-device transfer and collaboration.
