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 CO2 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 i...

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...

Energy Communities (ECs) are promoted by European Union to play a key role in achieving the goal of a just energy transition with active participation of citizens. Many countries are adopting relevant European Directives and integrate ECs in their legislative framework. To this direction, this paper concentrates on analyzing the existing conditions...

As European car manufacturers increasingly commit to fully electric vehicles in alignment with the European Green Deal and EU climate targets, the transition from internal combustion engines to electric vehicles necessitates a new skill set for engineers, particularly in Southeastern Europe. This paper examines the integration of industry feedback...

This paper presents a mixed-integer linear programming optimization model of a renewable energy community comprised of members with local generators, battery energy storage systems, electric vehicles, and heat pumps and thermal energy storage, thus representing a local multi-energy system. The goal of the paper is to analyze the impact of different...

Energy communities can take different measures to improve the economic savings derived from energy sharing, such as optimally aggregating members with diverse generation and load profiles or by shifting electricity demand throughout the day. Nevertheless, the magnitude of the cost savings from energy sharing are always bound by exogenous factors, s...

The financial benefits of energy sharing within a community are impacted by factors within the control of the community, such as internal rules for energy sharing, and by external factors, such as regulatory frameworks and fiscal policies. While much of the literature on energy sharing has focused on internal rules, there has been less attention pa...

The recent energy and economic crisis and the national status as candidate country for membership in the European Union (EU) indicates the need to prompt action to encourage active energy citizenship, so as to facilitate the energy transition and the decarbonization of the energy and heating system. Therefore, this paper seeks to contribute to the...

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...
