AbstractThe energy turnaround created a high volatility in the energy production based on renewable energy. To integrate renewable energy economically in buildings and smart cities an additional concept of energy storage and energy supply based on energy management concepts must be claimed. The political views have changed during the last years and energy efficiency in buildings is seen important because 35% of greenhouse gas is produced by the final energy consumption. The deployment of local energy production concepts is an important step to energy turnaround. To generate and distribute energy effectively in buildings, digital components such as sensors, actuators, meters, and energy management systems must be installed in the buildings and the digital components must be able to communicate via communication networks. The paper describes systems for local energy generation, necessary communication networks for buildings and smart cities and digitization applications in industrial buildings. As an example of energy management, the Oktett64 system is presented, which is based on Enterprise IT technology and has implemented AI and blockchain technology. Digitalization with platforms such as Oktett64 are based on technologies that are superior to today's often commercially available Programmable Logic Controllers. The article also shows how the future mobile communications standards 5G beyond and 6G can offer special solutions for the digitization of buildings in their edge clouds.

Nowadays, in the context of climate change, efficient energy management and increasing the share of renewable energy sources in the energy mix are helping to reduce greenhouse gases. In this research, we present the energy system and its management and the possibilities of its development through the example of an ecovillage. The basic goal of such a community is to be economically, socially, and ecologically sustainable, so the study of energy system of an ecovillage is especially justified. As the goal of this community is sustainability, potential technological and efficiency barriers to the use of renewable energy sources will also become visible. Our sample area is Visnyeszéplak ecovillage, where we examined the energy production and consumption habits and possibilities of the community with the help of interviews, literature, and map databases. By examining the spatial structure of the settlement, we examined the spatial structure of energy management. We formulated development proposals that can make the community’s energy management system more efficient.

Decentralized Energy

Until recently, the prevailing idea was that for the functioning of the energy system it is necessary to be composed of large plants and for energy to move from the centre of production to cities and places of consumption. With the advent of decentralized energy production systems and new technologies for their use, the original model is changing more and more. EU Directive 2018/2001 on the promotion of the use of renewable energy sources (RES) designates “prosumers”, i.e. at the same time both producers and consumers of renewable energy, as well as RES communities, while EU Directive 2019/944 introduced the term “citizen energy communities”, i.e. civil energy communities, provided that this Directive, in addition to the distributive production of electricity from RES, also includes electricity from other sources. EU member states are obliged to adopt their own regulations regarding the implementation of the directives, and after that the appropriate incentive measures. The Energy Communities initiative offers citizens new opportunities in terms of active involvement in energy issues. As they are decentralized RES-based projects, they promote the practice of sustainable energy production and consumption, as well as energy storage and exchange within the community. Traditionally passive consumer becomes an energy “prosumer”, a co-owner of a RES plant and a member of the energy community. There are thousands of so-called RES cooperatives in Europe, which are the most common organizational form of energy communities and can play an important role in the process of decentralization of the energy system. The transition to decentralized energy production has many advantages, namely: the use of local energy sources, increased security of local energy supply, shorter transport distances and reduced losses in energy transmission, encouraging community development and creating local jobs. The purpose of this paper is to bring closer to the general public in Serbia the concept of energy communities, what they are and what their role is, with most of the work dealing with energy communities in the EU.

The energy sector is constantly changing. Electromobility, improvement of energy efficiency, smart cities these are just some of the challenges that the present power industry is facing. The main goal for the power industry is to ensure the energy security of its customers, to develop low-community technologies which are mainly based on renewable energy sources and local raw materials. The transition from a centralized energy sector based mainly on conventional power plants to a distributed energy sector requires constant control and management of the generation and demand for energy. One of the solution existing since 2016 are energy clusters. The concept of their functioning is based on the civil-law agreement of locally operating entities that produce, sell, store and consume electricity, heat and cold. The main purpose of introducing energy clusters is the development of distributed energy. Energy clusters ensure the improvement of local energy security with relatively low outlays and low environmental impact. Technological development and installations based on renewable energy sources make energy clusters a beneficial and cost-effective solution for local energy sector. The article presents the idea of energy clusters functioning, and describes the current status of development. It also includes the hybrid systems characteristics of RES systems as an effective source of energy. The conclusion includes the legitimacy of the energy cluster development based on RES installations.

Amidst the hype of a ‘new’ energy regime in India with a singular focus on renewable energy, this paper offers a more scrupulous reading of renewables to set up a critical energy discourse. It offers a three-part analysis where it begins by questioning the entrenched idea of ‘renewables as science’ and its instrumental use of metrics and measurements to convey an unbelievable reach and significance. Highlighting the consistent invocation of a calculative ethos, it shows how an ‘empirics of targets’ relying largely on the lure and lore of a single numeric, installed capacity, is persuasively employed to gloss over the crucial distinction between the potential and reality of renewables. An associated consequence is not only its pegging to the speculative value of market-based energy production but also that it remains rooted in the assumptions of an existing system, that is, the logic of a carbon lifeworld. Renewables, as a result, display the tell-tale sign of a sustainability paradox, raising questions about their ability to master a transition to a post-fossil performativity, exasperated as they are by internal contradictions embedded within their core characteristics – efficiency/sufficiency and, more importantly, tensions between utilities and infrastructure. With loose connections to parallel initiatives such as the Smart Cities Mission, the transformative potential of renewables is undercut as it remains embedded within an abstract grid imaginary, challenging any effort to actualise it in and through the urban.

Energy Demands

Electric power reliability is one of the most important factors in the social and economic evolution of a smart city, whereas the key factors to make a city smart are smart energy sources and intelligent electricity networks. The development of cost-effective microgrids with the added functionality of energy storage and backup generation plans has resulted from the combined impact of high energy demands from consumers and environmental concerns, which push for minimizing the energy imbalance, reducing energy losses and CO2 emissions, and improving the overall security and reliability of a power system. It is now possible to tackle the problem of growing consumer load by utilizing the recent developments in modern types of renewable energy resources (RES) and current technology. These energy alternatives do not emit greenhouse gases (GHG) like fossil fuels do, and so help to mitigate climate change. They also have in socioeconomic advantages due to long-term sustainability. Variability and intermittency are the main drawbacks of renewable energy resources (RES), which affect the consistency of electric supply. Thus, utilizing multiple optimization approaches, the energy management system determines the optimum solution for renewable energy resources (RES) and transfers it to the microgrid. Microgrids maintain the continuity of power delivery, according to the energy management system settings. In a microgrid, an energy management system (EMS) is used to decrease the system’s expenses and adverse consequences. As a result, a variety of strategies and approaches are employed in the development of an efficient energy management system. This article is intended to provide a comprehensive overview of a range of technologies and techniques, and their solutions, for managing the drawbacks of renewable energy supplies, such as variability and load fluctuations, while still matching energy demands for their integration in the microgrids of smart cities.
