An article has been published in the international journal Energies
The peer-reviewed open-access journal Energies has published the article “Energy Analysis and Exergy Optimization of Photovoltaic-Thermal Collector” written by the project partners PhD candidate Sonja Kallio and Prof. Monica Siroux from INSA Strasbourg ICUBE University of Strasbourg.
The article was published in the Special Issue “Building Performance Simulation, Energy Efficiency and Renewable Energy Resources for Buildings”.
In the study, the operation of the solar-based micro-cogeneration system (PVT) under two different European climates was analyzed in terms of energy and exergy performance. The comparison between the PVT and photovoltaic (PV) panel performance was conducted as well. Finally, the PVT design was optimized using the multi-objective optimization technique.
The full PDF version of the publication can be download from the Energies website.
A photovoltaic-thermal (PVT) collector is a solar-based micro-cogeneration system which generates simultaneously heat and power for buildings. The novelty of this paper is to conduct energy and exergy analysis on PVT collector performance under two different European climate conditions. The performance of the PVT collector is compared to a photovoltaic (PV) panel. Finally, the PVT design is optimized in terms of thermal and electrical exergy efficiencies. The optimized PVT designs are compared to the PV panel performance as well. The main focus is to find out if the PVT is still competitive with the PV panel electrical output, after maximizing its thermal exergy efficiency. The PVT collector is modelled into Matlab/Simulink to evaluate its performance under varying weather conditions. The PV panel is modelled with the CARNOT toolbox library. The optimization is conducted using Matlab gamultiobj-function based on the non-dominated sorting genetic algorithm-II (NSGA-II). The results indicated 7.7% higher annual energy production in Strasbourg. However, the exergy analysis revealed a better quality of thermal energy in Tampere with 72.9% higher thermal exergy production. The electrical output of the PVT is higher than from the PV during the summer months. The thermal exergy- driven PVT design is still competitive compared to the PV panel electrical output.

State of Art Report
Work package 2 output: State of Art Report has been published and can be uploaded from the project website.
The Elsevier journal Energy and Buildings published an article “Development and experimental evaluation of grey-box models of a microscale polygeneration system for application in optimal control” written by the project partners from Hochschule Offenburg, Hochschule Karlsruhe and University of Freiburg.
Optimisation based economic despatch of real-world complex energy systems demands reduced order and continuously differentiable component models that can represent their part-load behaviour and dynamic responses. A literature study of existing modelling methods and the necessary characteristics the models should meet for their successful application in model predictive control of a polygeneration system are presented. Deriving from that, a rational modelling procedure using engineering principles and assumptions to develop simplified component models is applied. The models are quantitatively and qualitatively evaluated against experimental data and their efficacy for application in a building automation and control architecture is established.
The Elsevier journal Heliyon published an article “Application and analysis of a model based controller for cooling towers in compression chiller plants” written by the project partners Parantapa Sawant and Jens Pfafferott from Hochschule Offenburg.
Cooling towers or recoolers are one of the major consumers of electricity in a HVAC plant. The implementation and analysis of advanced control methods in a practical application and its comparison with conventional controllers is necessary to establish a framework for their feasibility especially in the field of decentralised energy systems. A standard industrial controller, a PID and a model based controller were developed and tested in an experimental set-up using market-ready components. The characteristics of these controllers such as settling time, control difference, and frequency of control actions are compared based on the monitoring data. Modern controllers demonstrated clear advantages in terms of energy savings and higher accuracy and a model based controller was easier to set-up than a PID.

Project Workshop at the Offenburg University of Applied Sciences
About 40 participants came to the first user workshop within the ACA-MODES project at the Offenburg University of Applied Sciences on Friday, 31 January 2020, to learn more about the planning and operation of decentralised energy systems.
During the workshop, the ACA-MODES project team gave the industrial partners, energy consultants, energy service providers, municipalities, energy cooperatives and scientists insights into the practical application of advanced tools for modelling and simulation of hybrid energy systems, for model predictive control and for data analysis. In addition, experts from renowned energy system research institutions and regional partners presented case studies and gave the participants insights into sector coupling and grid integration of building energy systems, which can be flexibly adapted to the size and market structure of the local energy system. During the lunch break, the participants were also able to get an impression of the new Regional Innovation Centre for Energy Technology (RIZ), which is currently under construction.
In the end, all participants agreed that the goal of the ACA-MODES project team – to build a bridge between science and users – had been achieved.
