Query: Data Model, Collection and Evaluation Framework for Local Energy Systems   Distributed ledgers are a new type of database technology that allows open
access to data stored across distributed, decentralised, publicly maintained
infrastructures. Current implementations of the such ledgers expect competition
between participants, are often energy hungry, poor in maintaining the natural
structure of data and suffer from scalability constraints. The aim of my
research work is to develop a distributed ledger-based middleware for data
modelling and collection on household energy generation and use, while
addressing scalability and energy inefficiency concerns of the ledger for this
particular application domain. The energy data collected and made available
through this middleware will be used for digital energy service delivery (e.g.,
automated peer to peer energy trading, topological estimations, etc.). The
middleware also provides a platform for a consumer focused digital energy
service delivery, as well as service model evaluation. The model evaluation
will enable the prospective service users to evaluate the suitability of the
given service for their needs before making a decision of service subscription.
