Special Issue Information

Dear Colleagues,

This Special Issue titled “Renewable Energy Integration toward a Sustainable Energy Transition” aims to collect original research, survey, and review articles on technologies, innovations, strategies, and solutions, which support the integration of renewable energy sources (RES) into all energy markets and the grid management, to achieve a sustainable energy transition. Focus shall also be laid on the safe utilization of grid resources and the end-customer inclusion, e.g., their impact and required behavior adaptation.

We may expect a scalable distributed smart energy system, both grid- and market-wise. Therefore, distributed control is a core topic, as well as the multi-supplier regime required to enable end-customers to transparently buy and sell energy on a share-by-share basis, possibly time- and usage-related. This requires capable demand-and-supply balancing that integrates grid safety based on adequate metering and accounting solutions.

Energy management based on precisely timed energy flows traded ahead of time, for example, via a private ledger system (blockchain), is an option, as well as traditional demand supply and excess purchase by aggregators, and also novel flat rate offers where, for example, purchasing an electric vehicle is bundled with the energy required for driving it. These independent supplies will probably co-exist on an open market.

The topics of interest include, but are not limited to:

  • Broad scale distributed RES integration: technical, operational, market-wise
  • Achieving behavioral change: assessing barriers, interrelations, and risks
  • Cooperative energy management: energy communities and solutions alike
  • Smart grid control strategies: distributed control for safety and robustness
  • Interoperability: secure open interfaces and operations among systems
  • Sustainable tariffing: impact and acceptance prediction, systemic risks
  • Customer-centered solutions: end-user integration in active transition
  • Utility services: providing, selling, and delivering added flexibility
  • Success stories, deployment examples, and regulatory issues solved

A Generic Framework for the Definition of Key Performance Indicators for Smart Energy Systems at Different Scales

The growing integration of intermittent renewable energy sources (RESs) and the increasing trend of shutting down fossil-fuel-based power plants has brought about the need for additional flexibility in energy systems. This flexibility can be provided in various forms, including controllable generation and consumption, storage, conversions, and exchanges with interconnected systems. In this context, an increasing focus is placed on the development of smart energy systems (SESs) that combine different types of distributed energy resources (DERs), information and communication technologies (ICTs), demand side management (DSM), and energy conversion technologies. The utilization of SESs can lead to multiple benefits for the stakeholders involved; therefore, the assessment of their performance is a primary concern. Due to their multidisciplinary nature, there are no known or universally accepted standards for assessing the performance of SESs. Previous efforts only define key performance indicators (KPIs) for individual homogeneous subsystems, focusing on a specific SES type and application area. This paper focuses on the development of a novel comprehensive KPI framework that can be applied to any type of SES, regardless of the application area. The proposed framework consists of four layers that specify the application area, the main SES requirements, and the involved stakeholders’ objectives. Next, the KPIs are identified for each of the stakeholders’ objectives. The proposed KPI framework is applied to the use case of a European research project with different application areas, to demonstrate its features. Finally, a repository of KPIs is identified for each use case with respect to the aforementioned SES requirements. Full article

To realise the energy transition, every renewable source shall at least partially contribute to the demand–supply balancing, including customer-owned controllable loads and energy sources. Their commonly small size and spatial occurrence suggests addressing volatility issues locally, using local flexibilities to mitigate their impact. This calls for simple and effective signalling that enables interaction among local stakeholders, including local producers and customers. According interfaces and information formats appear to not yet exist. In this article, we propose a traffic-light-like system that enables the local grid operator to trigger situation-aware customer behaviour, supporting grid stability when needed and, in return, allowing customers to fully exploit temporary grid capacity when no safety or stability issues persist. The applied intuitive deduction method based on existing coordination mechanisms and objectives indicates, without proof, that the proposed granular traffic light system can enable the distribution grid flexibility required to facilitate more renewable energy being produced and inserted by local customers, to relieve grid levels above from transporting and equalising volatile energy shares, and to improve the economics of distributed renewable energy sources.

The installation of rooftop PV systems in residential buildings and dwellings has increased rapidly in the past decade, and these systems have become a major source of renewable energy in many countries. This paper presents a new method of estimating the potential of rooftop PV systems to meet energy demands in residential districts by introducing a roof suitability factor. The method of assessment is based on an online tool called SunSPot, which uses a solar radiation heat map layer of building roofs and the PVSYST solar performance software. A sample of 400 houses from four suburbs considered in the Sydney City Council 2030 sustainability plan was selected to conduct the performance analysis of rooftop PV systems and develop a formula that can estimate the suburban annual energy production. The results show that if the dwelling roofs in residential suburbs could be covered by PV arrays it would produce enough electricity to exceed the local electricity demand and, in some suburbs, a surplus of more than 87%.
