To identify and tackle barriers in PV deployment.
To enhance the penetration of PVs in built environment.
To enhance buildings grid interaction using electric energy storage systems in 5 pilot areas. To design and implement proper policies and regulations.
European Union’s energy targets for 2030 include the transformation of the building stock to Nearly Zero Energy Buildings - nZEBs. NZEBs are characterized by reduced net-energy demand, where most of their energy needs are met by renewable energy sources, especially Photovoltaics. Consequently, in the following years, a considerable amount of intermittent solar generators will be connected in the electrical grid posing new challenges concerning the secure and reliable grid operation. As the number of NZEBs increases, PV integration in the distribution grids of BalkanMed region will be very difficult, unless buildings become more grid-friendly and policies and regulations are suitably adapted. High PV penetration levels may result in unacceptable stress on the electrical grids during hours with high solar power generation. The most important technical challenges that may arise include overvoltages, overloading of network equipment, and fault protection issues. To effectively address these challenges, the integration of Energy Storage Systems in NZEBs is considered as the most promising solution.
Enhancing storage integration in buildings with Photovoltaics (PV-ESTIA) is a project funded by the transnational Cooperation Programme Interreg V-B "Balkan-Mediterranean 2014-2020" and co-funded by the national funds.
The primary goal of PV ESTIA project is to:
The main project outputs are:
In the framework of the PV-ESTIA project, the performance of the proposed Innovative Management Scheme will be thoroughly evaluated under real-field conditions. All pilot installations are selected carefully with the aim to examine if and how the size of the Energy Storage Systems and the different geographical conditions affect the performance of the proposed innovative management scheme.
The two groups of pilot installations include the following cities:
First Group of Pilots includes:
The research committee building of the Aristotle University of Thessaloniki has been selected as pilot site for the installation of both 15 kWp PV system and 15 kWh ESS. Thе building is equipped with a building energy management system (BЕMS), thus allowing the full implementation and evaluation of the proposed innovative management scheme.
In this pilot site, a 20 kWh ESS will be additionally installed to the existing 20 kWp PV installation. The pilot site is located at the dormitories building of the Western Macedonia University οf Applied Sciences.
Six ESSs with nominal capacity of 7 kWh will be installed in five different prosumers with existing PV installations. Additionally, a 20 kWh ESS will be added to the existing PV installation in the municipality building of Nicosia.
Five prosumers will be selected for installing an ESS with a nominal capacity of 7 kWh to validate the performance of the proposed innovative management scheme.
7 kWh ESS will be established on the main building of the University of Skopje.
Second Group of Pilots
The second group of pilots includes the installation of Smart meters in prosumers and consumers installations.
Measurement data will be acquired continuously for a period of at least one year and an exhaustive statistical analysis will be performed to derive typical consumption and generation profiles for the Balkan-Med region.
The first international conference of the BalkanMed Programme
Date: 2017-11-29 18:11:28
The first international conference of the BalkanMed Programme project Enhancing Storage Integration in Buildings with Photovoltaics - PV ESTIA took place at the University of Cyprus. It served as a discussion platform about tackling barriers in integration of energy storage systems in buildings with PVs and their interaction with the grid. Assoc. Prof. Georgios Christoforidis provided information about the PV ESTIA project and how do we aim to change the way buildings with photovoltaics interact with the grid, thus paving the way towards nZEBs. Prof. Grigoris Papagiannis from the Aristotle University of Thessaloniki (AUTH) opened up the discussion how to tackle and avoid technical barriers of storage, do we need incentives for energy storage and should we focus on decentralized or centralized energy storage?

It also provided valuable insights into BalkanMed Communication & Dissemination Rules.
TRCWM presents a scientific paper during the 5th IEEE International Energy Conference in Limassol
Date: 2018-07-04 15:28:50
A presentation of a scientific paper related to PV-Estia project was implemented by the Technolocigal Research Center of Western Macedonia in June, 2018 during the 5th IEEE International Energy Conference in Limassol, Cyprus. The paper will be available in large international databases (IEEE Xplore, Scopus, etc) in the following months, ensuring that interested scientists and stakeholders will become aware of the work done in the PV-ESTIA project. It examines voltage quality problems in Low Voltage (LV) Distribution Networks (DNs) due to high Photovoltaic (PV) and Electric Vehicles (EVs) penetration. The proposed methodology considers Battery Energy Storage Systems (BESSs) along with the PV units in order to store the energy surplus that causes overvoltage during the high PV generation. This stored energy is utilized at night when the majority of the EVs is expected to be charged. Moreover, a Unified Particle Swarm Optimization (UPSO) algorithm is used in order to optimally schedule EVs charging during the night and under different charging modes. This scheduling is implemented under either an assumed continuous charging mode or an intermittent one. The objective function is set to be the optimal voltage profile. A real LV DN with real measured load data is examined. Variations have been taken into account about some EVs’ parameters and the results indicate that the voltage profile is significantly improved under the proposed charging schedule by the UPSO. If this charging schedule is combined with efficient exploitation of the BESS stored energy then the improvement is even higher. The proposed approach also improves energy efficiency towards the implementation of the Nearly Zero Energy Buildings (NZEB) concept.
