NEWSLETTER #1  PV ESTIA

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
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. These technical issues can be effectively tackled, using energy storage systems (ESSs) to store locally the energy that is not consumed during high generation periods. Additionally, installation of ESSs in buildings with PVs can increase the self-consumption by storing the surplus energy for later use and thus provide relief to the stressed feeders. Тhere is a strong need to develop a management scheme for the efficient coordination among PVs , energy storage systems, and the energy needs of the building.

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:
  • Enhance the integration of Photovoltaics and Energy Storage Systems in the building environment in 5 pilot areas, thus facilitating the transition towards Nearly Zero Energy Buildings;
  • Identify and tackle barriers in PV deployment;
  • Provide a new energy management solution for residential and commercial buildings, taking into consideration potential interactions with the electrical grid;
  • Transform buildings into a controllable energy source;
  • Design and implement proper policies and regulations.

The main PV ESTIA outputs are:

  • An innovative management scheme of PV+storage hybrid, making buildings grid-friendlier;
  • A generalized model assessing alternative policies related to implementation of such hybrids;
  • An online tool providing profitability estimation of such systems;
  • An advanced tool evaluating multiple policy scenarios;
  • Set of joint regulation recommendations in the form of roadmap for BalkanMEd region and joint policy recommendations targeting grid operators and relevant stakeholders. 

In the framework of the PV-ESTIA project, the performance of the proposed PV+storage Innovative Management Scheme will be thoroughly evaluated under real-field conditions. Pilot installations will be 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:

  • Kozani, Greece
  • Nicosia, Cyprus
  • Plovdiv, Bulgaria
  • Skopje, Macedonia
  • Thessaloniki, Greece

THE FIRST GROUP OF PILOTS:

THESSALONIKI:

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.

KOZANI:

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

NICOSIA:

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.

PLOVDIV:

Five current and new prosumers will be selected within the Plovdiv area for installing an ESS with a nominal capacity of 7 kWh to validate the performance of the proposed innovative management scheme.

SKOPJE:

7 kWh ESS will be established on the main building of the University of Skopje.
 


THE 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.
