In this newsletter, we are happy to bring you some of the most interesting outcomes of the project. ENGIE Laborelec explains the potential gains to the wind energy production by having the suitable data analysis tools, and the University of Aalborg investigates the impact of compressing monitoring data from the wind and solar parks. IBM presents the Streams and Incremental Learning (SAIL) library created in the context of MORE, and Athena Research details the method for detecting soiling of solar parks.
You are cordially invited to the bi-annual IBM-Athena colloquium series on the industry challenges due to the exponential growth of time-series data. The colloquium series strives to cover the challenges arising from high frequency and/or high volume time series data in various sectors like RES, water, inventory management etc.

Wind turbines generate optimal power output when the turbine blades are perpendicular to the wind direction. However, due to technical errors or malfunctioned sensors, this is not always the case - when a wind turbine does not face the wind it is defined as yaw misalignment. Detecting and correcting yaw misalignment creates a direct impact on the bottom line of wind farm companies.

MORE's 8th Plenary meeting (7th & 8th of December 2021) was hosted by the Information Management Systems Institute of the Research Center "Athena". For the first time, due to the COVID-19 pandemic, the meeting took place as a physical event at Athena's premises in Athens. In the context of this productive meeting, we discussed and resolved communication issues between the modules and reviewed the first year of the project.

MORE participates in the 85th Thessaloniki International Fair, which will take place with a physical presence at the Thessaloniki International Exhibition Center. This year's event is dedicated to Greece, with the central theme of the triptych Past-Present-Future, in the context of the 200th anniversary of the Greek Revolution. The aim is to contribute to the redefinition of the needs of Greek society, to stimulate its historical memory and to bring closer the citizen with the new digital services and technologies, the innovations, but also the Greek production. We are waiting for you at the stand of the General Secretariat for Research and Innovation (HALL 7, STAND 3) from 11 to 19 September.

The aim of this deliverable is to document how ModelarDB has been modified to efficiently ingest sensor data when running on edge nodes. The existingversion of ModelarDB is optimized for the data centernodes as it interfaces with unmodified versions of Apache Spark and Apache Cassandra for query processing and storage respectively. Thus, the emphasis is on selecting and integrating an alternative open-source query engine and storage layer that are optimized for the edge nodes. The storage layer is required to store the ingested data until it can be transferred to the data centernodes, while the query engine is required to execute queries on the sensor data during ingestion.

This deliverable presents how modelscan be used to compress large amounts of time series data efficiently. This is needed to be able to store and analysethe huge amounts of sensor data available from modern wind turbines and solar panels. The currently available MORE datafrom ENGIEis then investigatedin details. It is found thatmany parts of the time series can be modelled by a quadratic function.Based on this a new model type is proposedto be added to the ModelarDB model-based Time Series Management System (TSMS). Further, it is found that many of the time series can be derived from other timeseries. Based on this it is proposed how to avoid physical storage of time series that can be derived from othertime series.The ENGIE dataset is also compressed by use of models in ModelarDB and it is found that even with lossless compression, the required storage is reduced by 19% and with an error bound of 10%, the reduction is bigger than 76%, compared to the original data size.

Deliverable 5.1 is a baseline document for the MORE project, outlining generic user requirements as well as specific use cases. The later will be used for compliance testing of the architecture and for the subsequent verification and performance estimation of the MORE system. The use cases were selected to be both representative of actual needs (with commercial exploitability), as well as challenging in terms of the MORE system KPIs. Overall, six use cases are described, equally spanning wind and solar RES applications.The selected use cases address a range of high-level system requirements, from “real time” feedback from the cloud to the edge, to application of complex analytics over vast amount of timeseries data, to support costly maintenance decisions. Some use cases call for improvements in existing processes, whereas the rest introduce novel capabilities for future RES plants. Thus, by validating the feasibility and performance of the implementation of the use cases, we expect to demonstrate the gains from the introduction of MORE system to existing processes, as well as the adaptability of the MORE platform to support future functionalities in the RES production plants.

The aim of the deliverable to describe the overall plan of the project, the processes for monitoring and reporting, the risk mitigation plans and operational oversight.There is emphasis on updating the risk and quality strategiesand on documenting the detailed plans for the next 6 months of the project.The document covers implementation procedures and structures and sets out key responsibilities for the engagement and interaction with relevant stakeholders and the European Commission.The described procedures are updates and detailed versions of the one put forward on the GAand the proposal. They reflect the updated consortium, the decisions taken in the context of Consortium Agreement and demonstrate how the Consortium will achieve the project objectives, how the oversight ofpartners’ progress on specific tasks will take place and how the Consortium will securethe timely delivery of project results.
