Wave Architecture Applications Wave Apps are managed by the Wave Application Manager (WAM). Wave Apps are extensions to Wave that add business logic to meet user-specific objectives. System System level objectives are carried out by the Distribution Network Manager (DNM). The DNM stores the full representation of the DER portfolio including assets, connectivity, and capabilities of the overall system. Groups Groups of Assets are hosted and managed by Control Area Managers (CAM). Groups give Spirae Wave™ the ability to aggregate DER into dynamic portfolios assignable to different system capabilities. Assets Assets are hosted by Energy Resource Managers (ERM). Spirae Wave™ uses a standardized catalog of assets to easily interface with and manage assets.

Lessons Learned • While grid connected, low cost operation is generally preferred by microgrid owners.

• Better management of renewable and load transients required if peak management is

the objective and/or a penalty is associated with exporting power to the grid – not sufficient to just increase renewable penetration.

• While islanded, better management of renewable and load transients required to ensure prolonged and safe operation of the microgrid – not sufficient to just increase renewable penetration.

• Better management of energy storage state-of-charge is required. Energy storage can play an important role in management of transient capacity in a microgrid.
