The growing penetration of renewable energy sources (RES) in the electrical power sector has increased the amount of distributed generation (DG) units connected at the distribution system level. In this context, new balancing challenges have arisen, creating the need for a novel use case methodology to enable an active role at the distribution system level such that transmission system operators (TSOs) can coordinate with distribution system operators (DSOs) with regard to connected resources for balancing purposes. In this study, the exploitation of the DSO-connected resources for balancing purposes in a market environment is proposed and evaluated via a novel business use case (BUC) methodology based on the categorization of IEC 62913-1. More specifically, in order to address different balancing market situations, two scenarios are considered with regard to the BUC. The first one represents the data exchange between the TSO, the DSO, and the balancing service provider (BSP). The second one represents an alternative scenario where data are exchanged directly between the TSO and the DSO, where the DSO also takes on the role of the BSP. The proposed BUC was also developed in order to validate the required data modeling and exchange mechanisms between DSOs and TSOs in order to exploit DSO-connected resources for overall system balancing purposes across different time scales.

The electric power sector in countries suffering from crises and wars such as Syria, Iraq, Yemen, Libya, etc., is among the most affected infrastructures. Since this sector plays a vital role in the economic growth and in improving people’s quality of life, the post-crisis reconstruction of this sector must take into account the requirements and concepts of sustainable development (SD) in addition to technical and economic considerations. This article discusses the role that renewable energy sources (RES) can play in achieving SD in the post-crisis reconstruction phase of the Syrian Electric Power Sector (SEPS) as a case study. Based on the available data, the study period was chosen from 2005 to 2017 and divided into two periods. In the first period (2005–2010), which is the pre-crisis period, the structure of the SEPS and its main characteristics were described while the adoption of RES solutions and SD concepts were investigated. In the second period (2011–2017), the crisis period, the satiation of the SEPS and impact of the crisis were evaluated. The challenges that faced the adoption of SD concepts and RES solution were also addressed at this stage. Based on analysis and comparison of the available data, several scenarios were discussed to evaluate the role of RES in achieving SD in the post-crisis reconstruction phase of the SEPS. EnergyPLAN software was used for the techno and socio-economic evaluation of these scenarios. Our results emphasize the importance of the adoption of RES solutions in the reconstruction phase, as these can help promote SD concepts (reducing greenhouse gas emissions, protecting the environment, increasing energy efficiency, creating jobs, etc.) and securing the electric supply of the SEPS while enhancing its stability.

Power generation through the renewable energy sources has become more viable and economical than the fossil fuel based power plants. By integrating small scale distributed energy resources, microgrids are being introduced as an alternative approach in generating electrical power at distribution voltage level. The power electronic interface provides the necessary flexibility, security and reliability of operation between micro-sources and the distribution system. The presence of non-linear and the unbalanced loads in the distribution system causes power quality issues in the Microgrid system. This paper explores and reviews different control strategies developed in the literature for the power quality enhancement in microgrids.

Renewable energy sources (RES) are gradually becoming one of the key elements in the process of achieving energy efficiency worldwide. This trend can be observed in many developed Western economies—for example, in the United States, as well as in the United Kingdom. Hence, the role of innovative policies for promoting energy efficiency is becoming crucial in transition to the post-carbon economy. The shift to the carbon-free future make all actors to face forgoing commitments Nevertheless, customers and residential households are the first and the most important players in the pursuit of the energy-efficient future. Without them, carbon-free economy based on RES would never take the shape as envisaged. Our paper focuses on the innovative strategies and policies studying the effect and the scope of RES penetration into the households. We employ and empirical analysis of the effects from using RES in households using an example of the residential households in the northwest region of the United Kingdom (UK) with and without solar photovoltaic (PV) panels and electric vehicles (EV). We analyse the four scenarios that are aimed at analysing the system dynamics and providing differentiation between systems in terms of the varying values of the gross demand, tariffs, metered import, and the total revenue. Our results demonstrate that the solar PV leads to the transfer of costs and wealth regardless of the ownership of PV and EVs. Solar energy generation reduces the share of UK solar PV households per kWh costs of the distribution system which causes the augmenting of the per unit charges as well as to the changes in payments for the electricity that impoverishes less wealthy customer groups. It also becomes clear that with the increase of EV penetration, the existing energy efficiency schemes would have to be revised.

Over the last decades, the discussion on climate change, together with catastrophic events in the power sector, has raised global interest for radical policy changes. Since the year 2000, Germany´s Renewable Energy Sources Act (EEG) has been a forerunner in triggering large-scale decentralized deployment of renewable energy. Although built on a relatively large social consensus, the consequences of the German ‘Energiewende’ have also raised conflicts between communities and investor-oriented project developers. This chapter reviews the increasing role of energy co-operatives as means to involve civil society, mitigate conflicts in planning, and distribute subsidies more evenly among a variety of often rural stakeholders.

The subject of this chapter is the governance system of the distribution system operators (DSOs), i.e. the companies that own, operate and develop regional and local electricity networks. These companies are natural monopolies, and subsequently need strong regulation by public authorities and/or by consumers. The role of the DSOs has been changing fundamentally in recent years, together with the rest of the electricity system, due to the transition from stored fossil fuel-based electricity to electricity based on fluctuating renewable energy sources. The paper analyses the changing circumstances for the DSOs in the development of integrated smart energy systems, based on an innovative theoretical framework with a strong focus on ownership in the understanding of governance of natural monopolies. After a comparative analysis of shareholder versus consumer ownership, based on two cases, the paper sets up several conclusive recommendations about ownership, governance and the new role of the DSOs in the developing smart energy system.

The electrical power sector plays an important role in the economic growth and development of every country around the world. Total global demand for electric energy is growing both in developed and developing economies. The commitment to the decarbonization of economies, which would mean replacing fossil fuels with renewable energy sources (RES) as well as the electrification of transport and heating as a means to tackle global warming and dangerous climate change, would lead to a surge in electricity consumption worldwide. Hence, it appears reasonable that the electric power sector should embed the principles of sustainable development into its functioning and operation. In addition, events such as the recent European gas crisis that have emerged as a result of the massive deployment of renewables need to be studied and prevented. This review aims at assessing the role of the renewable energy in the sustainable development of the electrical power sector, focusing on the energy providers and consumers represented both by businesses and households that are gradually becoming prosumers on the market of electric energy. Furthermore, it also focuses on the impact of renewables on the utility side and their benefits for the grid. In addition, it identifies the major factors of the sustainable development of the electrical power sector.

The decarbonization of the power sector involves electrification and a massive deployment of variable renewable energy sources, leading to an increase of local transmission congestion and ramping challenges. A possible solution to secure grid stability is local flexibility markets, in which prosumers can offer demand-side flexibility to the distribution system operator or other flexibility buyers through an aggregator. The purpose of this study was to develop a framework for estimating and offering short-term demand-side flexibility to a flexibility marketplace, with the main focus being baseline estimation and bid generation. The baseline is estimated based on forecasts that have been corrected for effects from earlier flexibility activations and potential planned use of internal flexibility. Available flexibility volumes are then estimated based on the baseline, physical properties of the flexibility asset and agreed constraints for baseline deviation. The estimated available flexibility is further formatted into a bid that may be offered to a flexibility marketplace, where buyers can buy and activate the offered flexibility, in whole or by parts. To illustrate and verify the proposed methodology, it was applied to a grocery warehouse. Based on real flexibility constraints, historic meter values, and forecasts for this use-case, we simulated a process where the flexibility is offered to a hypothetic flexibility marketplace through an aggregator.

Abstract The integration of Dispersed Generation (DG) is by far the most important and challenging issue that modern power systems are facing nowadays, and is the only way of exploiting Renewable Energy Sources (RES) for electric production. This revolution is running particularly fast in Europe, where significant incentive schemes have been promoted by many Member States in order to match the targets decided by the European institutions. As a consequence of the important share of RES already connected (especially to low voltage and medium voltage networks), new technical challenges have to be faced both at a distribution network level and at a transmission system level. Some of these challenges are covered by Smart grids that represent a new framework for improved management of distribution and transmission networks with attention to interoperability, security, resilience problems, and quality of service (QoS). It is recognized that an intelligent use of Information and Communication Technology (ICT), as enabling technology, is the only approach able to solve new problems arising on energy networks due to larger DG penetration, without hindering system security and QoS.The paper focuses on the Italian case and in particular on the Italian regulatory framework for developing Smart Grids, and describes the technical foundations of the regulatory innovations introduced by the Italian energy regulatory authority (Autorità per l’energia elettrica e il gas - AEEG). After a selection process based on cost/benefit assessment, some demonstration projects for Smart Grid proposed by Distribution System Operators have been awarded with special capital cost remuneration (extra WACC of 2% for 12 years, on top of the ordinary WACC equal to 7% for distribution investments). The smart grid demonstration projects founded by AEEG introduce and test a new advanced management of DG in order to avoid the problems coming from reverse power flowing and maintain the necessary level of security, availability and quality of service.

Durch den Übergang in Smart Grids erhalten Stromnetze die notwendige Flexibilität, um auf die steigende Volatilität der Stromversorgung zu reagieren. Das standardisierte Smart-Grid-Architecture-Modell und die Use-Case-Methodik dienen dabei als Rahmen, um Smart Grids zu entwickeln. Ein methodischer Rahmen für den Aufbau von Industrial Smart Grids fehlt derzeit noch, ist aber besonders notwendig, um Energieflexibilitätsmaßnahmen für Industrieanlagen umzusetzen. Der hier vorgestellte methodische Ansatz liefert eine Blaupause für den Aufbau eines Industrial Smart Grid für Energieflexibilität. Mithilfe der Anpassung des Smart-Grid-Architecture-Modells und der Use-Case-Methodik wird ein Industrial-Smart-Grid-Architecture-Modell umgesetzt.   Through their transition into Smart Grids, electrical power grids gain the neccesary flexibiltiy to respond to increasing electrical supply volatility. The standardized Smart Grid Architecture Model and Use Case Methodology serve as framework to develop Smart Grids. Currently, there is still a lack of such a methodical framework for setting up Industrial Smart Energy Grids and it is particularly necessary to implement energy flexibility measures in industrial plants. The methodical approach presented here provides a blueprint for building an Industrial Smart Grid for energy flexibility by adapting the Smart Grid Architecture Model and the use case methodology .

Abstract Most researchers of the problems and prospects of the forest sector focus their attention on issues related to the concept of sustainable development. Sparsely wooded regions of Russia face a lot of obstacles, which makes the search for promising directions for the development of the forest sector in these regions with an active role of state support urgent. The work investigates the forest sector of Kursk region: the main problems and trends observed in its forest sector are noted, the key features of its forest resources are discussed. The directions for the development of the forest sector in the region and the related tasks of state support are formulated. All proposals are based on an orientation towards stimulating the use of local wood raw materials in those types of regional industries that are least demanding on the quality of raw materials. The following is proposed: (a) development of elements of “forest-oriented” environmental legislation; (b) regulatory support of demand for local renewable energy sources through diversification of heat supply to social infrastructure facilities; (c) setting quotas for the share of local wood raw materials consumed by enterprises.
