Grid impact indicators hold valuable information
about a prosumer when interpreted carefully. This makes them
quite useful for benchmarking different demand side management
schemes and studying active buildings. In this paper,
the effects that battery storage has on five such indicators
have been addressed in detail. Their values were calculated by...
Three load matching indicators (self-consumption rate, self-sufficiency rate, loss of load probability) and the CO 2 emissions were evaluated for 55 Cypriot households with 3 kWp rooftop photovoltaic (PV) generators. The calculations were performed using 30-minute generation and consumption data from a large scale smart meter project in Cyprus. To...
This paper provides a systematic review of 34 large-scale projects of power-to-heat demand response. The projects have been classified in terms of location, size, technical implementation and objective. The chronological ordering of the reviewed projects enables key takeaways to be drawn considering other developments in the energy sector, such as...
Due to the potential for deploying distributed generation, improving energy efficiency and adopting sustainable energy-related practices, consumers provide significant value in the energy sector transformation. If their interests and goals are similar, they can group together and form energy communities. Energy communities enable consumers to joint...
This paper proposes an energy sharing method for collective self-consumption called virtual net-billing. The proposed method enables the members of an energy community to fairly share energy in real-time, based on their individual contribution. To achieve this, a mathematical model is developed, which separates the total self-consumption of the com...
Grounded in the idea of meeting the needs of generations across time, sustainable development bears a close relationship to the way in which humanity consumes energy. Nevertheless, the historic notion that energy demand growth reflects improved living standards, economic development and prosperity are challenged when sustainability constraints and...
The energy shared through collective self-consumption determines the economic savings of an energy community and the revenue losses of its electricity supplier. In this paper, we statistically explore this quantity, based on a sample of 200 hypothetical energy communities. It is found that a typical community shares (4.69 ± 1.26) % of the annual ge...
Long term-energy planning has gradually moved towards finer temporal and spatial resolutions of the energy system to design the decarbonization of the society. However, integrated assessment models (IAMs), focusing on a broader concept of sustainability transition, are typically yearly-resolution models which complicates capturing the specific supp...
In recent years, a growing number of prosumers are beginning to form coalitions to jointly invest in renewable energy projects and share energy among themselves, either through peer-to-peer markets or collective self-consumption. The aim of this paper is to evaluate the fairness of three methods that can be used to financially settle the energy sha...
The impact of waste policies and measures from National Determined Contributions (NDCs) on the Sustainable Development Goals (SDGs) is unexamined and creates conditions for policy conflict and incoherence. This participatory case study of North Macedonia quantifies synergies and trade-offs. Our results show twelve times more synergies than trade-of...
Since 2015, the intended climate actions of the Paris Agreement signatories have been reported as nationally determined contributions (NDC). These climate actions are fully aligned with the 13th Sustainable Development Goal (SDG) which calls for urgent action to combat climate change. The same, however, cannot be said for their relation to the othe...

This paper is an editorial for the virtual special issue (VSI) of Renewable and Sustainable Energy Reviews (RSER) dedicated to the 14th Conference on Sustainable Development of Energy, Water and Environment Systems (SDEWES 2019) held from October 1, 2019 to October 6, 2019 in Dubrovnik. The VSI published both high quality review papers and original...
The Agenda 2030 defines 17 Sustainable Development Goals (SDGs) that act as a common global framework when pursuing economic development alongside reduced environmental damage and social equality. Achieving sustainable communities is related to one of these goals. In that context, energy communities have been introduced as legal entities that empow...
Recent evidence shows that the energy system is on the verge of a new leap driven by significant cost reductions of renewables, appalling environmental concerns and a tendency to digitize and decentralize the operation of energy systems. In this new paradigm, it is the role of science to enable the transition towards a sustainable energy system by...
Implementing sophisticated battery control algorithms by overriding the inverter’s built-in battery controls may introduce technical bottlenecks and additional costs. Such an approach is therefore rarely justified for small scale, behind-the-meter storage. This paper focuses on determining the parameters of an inverter-enabled rule-based control st...
Coupling batteries with photovoltaic generators in buildings can improve the building’s self-consumption and reduce its reliance of the grid. To quantify the effects of different battery charge/discharge rates on self-consumption and peak power exchange, four grid impact indicators have been analyzed – self-sufficiency rate, self-consumption rate,...
In order to determine the most suitable storage system for buildings with photovoltaic generators (PVs), a holistic analysis of the energy consumption is often required. In that sense, this paper provides a comparative assessment of thermal and battery storage in the context of nearly zero energy buildings (NZEBs). A NZEB with a PV, heat pump and a...
Many traditional heating systems which are based on fossils face challenges such as lack of investment or unfavorable price regulations, low technical performance, environmental impacts and negative consumer perceptions. The CoolHeating project which is, funded by the EU’s Horizon 2020 programme and presented in this paper promotes the implementati...
The fact that the heating and cooling demand in Europe accounts for around half of its final energy consumption has gained much attention, since very little had been done in the past to address this issue in a sustainable manner. Therefore, it is important to promote renewable heating and cooling concepts. The CoolHeating project, funded by the EU’...
The energy hub concept has proven itself highly useful for the integrated modelling of smart energy systems and has been widely applied for analyzing systems of multiple, mutually interconnected consumers of different energy carriers. A thorough literature review sheds light on the tendency of recent works to simplify the network flows, mainly thro...

The Balkan Med (BM) region is facing the challenge of sustaining and increasing the growth of PV systems that is endangered by several barriers and their unpredictable nature. This is especially important in the built environment as member states are developing plans to increase the number of Nearly Zero Energy Buildings (NZEB), which most probably employ PV’s , in order to reach their 2030 climate change targets.
As the number of NZEBs increase, PV integration in the distribution grids of BM region will be very difficult, unless buildings become more grid-friendly and policies/regulations are suitably adapted
In the above context, the overall objective of project is to enhance the penetration of PV’s in built environment. This will be achieved by using storage, which will transform the building into a more predictable power source. With the high solar potential of the BM region and the decreasing cost of PV/storage systems, such a solution is becoming cost-efficient as well Project aims to change the way buildings with PV’s are treated (i.e. selling energy to grid) and instead conceptualize them as systems that must efficiently interact with grids. Also, it aims to alleviate the above barriers and pave the way for unobstructive NZEB development
Main outputs are
1) an innovative management scheme of PV+storage hybrid, making buildings grid-friendlier;
2) a generalized model capable to assess alternative policies related to implementation of such hybrids;
3) An online user-friendly tool able to provide a good first estimate of the profitability of such systems under a specified policy, targeting prospective investors and stakeholders;
4) An advanced tool able to evaluate multiple policy scenarios, targeting policy makers;
5) Set of joint regulation recommendations in the form of roadmap for BM region, targeting grid operators and relevant stakeholders/engineers;
6) Set of joint policy recommendations targeting mainly policy makers and interested stakeholders.
The planned approach comprises
1) design the novel management scheme;
2) establish a variety of pilots in each country to maximize impact;
3) widely disseminating results and outputs in the BM region and beyond;
4) bring together key actors to receive feedback and produce targeted outputs to the BM region;
5) follow an open source approach with freely available data & tools to trigger replication.
