An electric energy Residential Information System
The eeRIS platform is a research project that aims at providing useful information to electric energy residential consumers with regards to their electric energy consumption. The ultimate goal of the project is for the consumers to get a better understanding of their consumption’s nature and to subsequently be able to reduce it.
The aforementioned goals are set to achieved by the following actions:
- Design and implementation of a low cost, high accuracy smart metering device, which will be connected to a central point of the residential electric installation. This device will provide sampled electric measurements such as total current and voltage values.
- Design and implementation of a low cost computation device that will be able to collect measurement values sampled by the smart metering device, process them and communicate the results to the end user.
- Implementation of algorithms for the processing of the electric consumption measurements, that include the disaggregation of the overall measurements to individual load curves, the statistical analysis of the data as well as their transformation to a form comprehensible by the end user.
- Implementation of back-end services for storing and processing the results of the data processing by the computation device and the applied algorithms.
- Implementation of the necessaary User Interface that will bridge the back-end services and the end user, driven by the optimization of the end user experience as a primary requirement, as well as the dissemination of the suggested solution to the market.
The smart meter is a low cost, high accuracy device, which is connected to a central point of the electric residential installation and provides sampled measurements of the total current and voltage values. The sampled measurements include values both in the basic frequency, as well as in harmonic frequencies.
eeRIS platform will manage electric energy consumption data with characteristics that classify them to the field of Big Data. Therefore, a dedicated Big Data Management System (BDMS) was designed and implemented to support Big Data in the first place. The BDMS, called cenote, provides a RESTful API for receiving and handling requests, such as requests for storage and retrieval of chunks of data.
Consumption Measurements Analysis Algorithms
The measurements analysis algorithms will serve multiple functionality, covering current consumer information requirements with respect to their energy consumption, as well as possible future services that might be requested by Energy Providers (EPs) or Distribution Network Operators (DNOs) in return for a more profitable energy supply contract. To that aim, the original measurements data will first be decomposed to individual load curves and, at a later stage, the resulting information will be transformed to a user-friendly format, so it is easier comprehensible by the end users.
The Power Systems Lab (PSL) of the Electrical and Computer Engineering department of the Aristotle University of Thessaloniki covers knowledge and technical areas such as electric energy generation, transmission and distribution as well as economic function and sustainability of power systems, among others. PSL has been involved in more than 70 European, bi-lateral and national contract projects, mostly related to the research and development of power systems, renewable energy sources, electric power and consumption control, environmental impacts from power generation and applications of Information Technologies. It also co-operates closely with local energy authorities, energy market participants and power producers.
The Inelligent Systems & Software Engineering Labgroup (ISSEL) has proven to be an active member of the Aristotle University’s research and development by having participated in more than 30 projects, that are related to research in the field of intelligent systems, autonomous agents, service-oriented robotics as well as applied machine learning, knowledge discovery and informatics applications. The Intelligent Systems and Software Engineering Labgroup with a scope of Software Development for Information Processing and Data Analytics has established a quality management system that is in conformance with the International Standard EN ISO 9001:2015.
etris was established in 2013 with the aim to provide services and products in the field of electronics applications. The company is comprised of Electrical and Computer Engineers with many years of experience and offers business solutions via dedicated services and products, such as the development of electronic devices as well as the repair of electronic equipment. Furthermore, the company meets the requirements of the industrial and the general technological sector by thoroughly studying each individual need to always offer the most reliable solution.

Second project meetup
The second project meetup, with the participation of all stakeholders, took place at the facilities of the Dissemination Center for Research Results of the Aristotle University of Thessaloniki on 17 January 2019. During the meetup, the various teams presented the results of their work so far, as it was planned in the September meetup. Finally, future goals and detailed planning for their completion were set.
First project meetup
The frist project meetup took place at the facilities of the Dissemination Center for Research Results of the Aristotle University of Thessaloniki on 5 September 2018. In the presence of all the stakeholders, the main focus of the meetup was the definition of the initial goals of the project and the adoption of a common understanding and work plan to reach them.
