A lack of multi-level connectivity between the management systems of smart grid actors and cyber-physical systems of distributed energy resources (DERs) impedes transition toward decentralized grid architecture driven by active network management. This article focuses on Web of Things (WoT) concept as a possible enabler of uniform machine type access to DERs. The results of the paper provide a blueprint of WoT adoption patterns in smart grid domain through the example of microgrid management system (MGMS). Moreover, this article delivers work-in-progress implementation of the metadata registry that facilitates the automated service-oriented discovery of MGMSs by aggregator management systems for purposes of market and grid.
