Uniform Web of Things based Access to Distributed Energy Resources via Metadata Registry

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.publishedVersionPeer reviewe

Information Exchange Platform for Enabling Ancillary Services from Distributed Energy Resources

The operation of the electrical grid is going through a major change. In future, also small-scale distributed energy resources (DERs) need to be utilized in system operation. Increasing penetration of DERs set new challenges for the grids but also open new possibilities in grid and system operation. Smart utilization of DERs would decrease the total costs of the system but barriers for widespread DER ancillary services still exist and include, amongst others, the lack of widely accepted interoperable communication interfaces and the inadequate number of studies going beyond simulations. This paper describes the development of an information exchange platform that enables interoperable data exchange between different energy system actors enabling more efficient use of customers’ and other market actors’ DERs in system operation. The operation of the developed information exchange platform is demonstrated with an example use case that considers utilizing DERs for frequency control through the frequency containment reserve market.acceptedVersionPeer reviewe

Integrated Business Platform of Distributed Energy Resources:Case Finland

The present energy system is facing various challenges in the near future due to changing demand and productions structures. Novel ideas are required to address the control of large number of the flexible resources. The paper aims to introduce integrated business platform of distributed energy resources in Finland. The platform is used to exchange information between laboratories, pilots, and actual facilities of all market participants. The paper describes the bare minimum information exchange requirements of some use cases for the integrated business platform to enable novel business opportunities for monitoring, verification, and application of flexibility services of microgrids and energy communities for the purposes of transmission and distribution grid management. The proposed information exchange platform is based on definition of use cases for the smart grid architecture model.publishedVersionPeer reviewe
