For those working in the sector of energy efficiency, we present the Optimal sizing calculator developed by LARES team within the project Store4HUC, financed trough the Interreg Central Europe programme. It is an in-depth tool for the advanced users like energy experts and others working in that field. Optimal parameterisation of photovaltaic and battery energy storage systems are supporting the customers to save costs and be more environmental friendly at the same time!
Photovoltaic (PV) systems are widespread renewable energy sources that can be installed at a variety of locations. Because of their sun dependence, they provide more than enough energy during the day, but no energy during the night. Since the prices of selling electrical energy to the utility grid are considerably lower than the prices of buying the energy, having a battery energy storage system (BESS) can ensure that the excess of energy is stored and used later. Not only does a PV system in a combination with a BESS reduce monthly electricity bill for a consumer, it equally contributes to the environmental protection in terms of reduced CO2 emissions.
To maximize the contributions while minimizing the price of the installations, the calculator finds the optimal sizes of a PV and a BESS for a site. Those sizes are peak power of the PV system, energy capacity and power converter rated power of the BESS. The calculator uses typical yearly consumption profiles of a variety of consumers, but if you have your own consumption profile recorded you can use it to calculate your optimal parameters more accurately.
You can download this valuable tool for free here and soon find out your optimal kWp-kW-kWh combination!
In this short video our researcher Filip Rukavina is explaining how to download the Optimal Sizing calculator, install it and get it started.

On January 26th, Croatian radio station, Radio Sljeme broadcasted an interview with 3Smart project coordinator dr. sc. Mario Vašak within their science show ''Iz svijeta znanosti''. Dr. sc. Mario Vašak hosted the show at the Faculty of Electrical Engineering and Computing to present the main objectives of the 3Smart project and to familiarize the listeners with the 3Smart concept as well as with the importance of the whole energy sustainability concept. An audio recording of the show can be reproduced by clicking on the following link: Audio
On 16th January 2017 a public presentation of the 3Smart project was held in Zagreb on the premises of University of Zagreb Faculty of Electrical Engineering and Computing who is the lead partner on the project. The event attracted a significant number of participants from different sectors representing government, industry and academia. The project 3Smart is funded by the European Union through the Interreg Danube Transnational Programme.
| On January 17th, Jutarnji list, Croatian daily newspaper published an article about project 3Smart (Smart Building - Smart Grid - Smart City where the University of Zagreb Faculty of Electrical Engineering and Computing is the lead partner. The article highlights the importance of such a project recognizing the need for sustainable, reliable solutions for the transmission, distribution and use of energy resources and the role of the Innovation Centre Nikola Tesla in this and future projects.
