Abstract
The chapter analyses the role of smart grid technology in the German energy transition. Information technologies promise to help integrate volatile renewable energies (wind and solar power) into the grid. Yet, the promise of intelligent infrastructures does not only extend to technological infrastructures, but also to market infrastructures. Smart grid technologies underpin and foster the design of a “smart” electricity market, where dispersed energy prosumers can adapt, in real time, to fluctuating price signals that register changes in electricity generation. This could neutralize fluctuations resulting from the increased share of renewables. To critically “think” the promise of smart infrastructure, it is not enough to just focus on digital devices. Rather, it becomes necessary to scrutinize economic assumptions about the “intelligence” of markets and the technopolitics of electricity market design. This chapter will first show the historical trajectory of the technopolitical promise of renewable energy as not only a more sustainable, but also a more democratic alternative to fossil and nuclear power, by looking at the affinities between market liberal and ecological critiques of centralized fossil and nuclear based energy systems. It will then elucidate the co-construction of smart grids and smart markets in the governmental plans for an “electricity market 2.0.” Finally, the chapter will show how smart grid and smart metering technology fosters new forms of economic agency like the domo oeconomicus. Such an economic formatting of smart grid technology, however, forecloses other ecologically prudent and politically progressive ways of constructing and engaging with intelligent infrastructures.

Abstract
Purpose
At present the energy generation and distribution landscape is changing rapidly. The energy grid is becoming increasingly smart, relying on an information network for the purposes of monitoring and optimization. However, because of the particularly stringent regulatory and technical constraints posed by smart grids, it is not possible to use ordinary communication protocols. The purpose of this paper is to revisit such constraints, reviewing the various options available today to realize smart‐metering networks.
Design/methodology/approach
After describing the regulatory, technological and stakeholders' constraints, the authors provide a taxonomy of network technologies, discussing their suitability and weaknesses in the context of smart‐metering systems. The authors also give a snapshot of the current standardization panorama, identifying key differences among various geographical regions.
Findings
It is found that the field of smart‐metering networks still consists of a fragmented set of standards and solutions, leaving open a number of issues relating to the design and deployment of suitable systems.
Originality/value
This paper addresses the need to better understand state‐of‐the‐art and open issues in the fast‐evolving area of smart energy grids, with particular attention to the challenges faced by communication engineers.

Abstract
Purpose
The purpose of this article is to propose and evaluate a novel system architecture for Smart City applications which uses ontology reasoning and a distributed stream processing framework on the cloud. In the domain of Smart City, often methodologies of semantic modeling and automated inference are applied. However, semantic models often face performance problems when applied in large scale.
Design/methodology/approach
The problem domain is addressed by using methods from Big Data processing in combination with semantic models. The architecture is designed in a way that for the Smart City model still traditional semantic models and rule engines can be used. However, sensor data occurring at such Smart Cities are pre-processed by a Big Data streaming platform to lower the workload to be processed by the rule engine.
Findings
By creating a real-world implementation of the proposed architecture and running simulations of Smart Cities of different sizes, on top of this implementation, the authors found that the combination of Big Data streaming platforms with semantic reasoning is a valid approach to the problem.
Research limitations/implications
In this article, real-world sensor data from only two buildings were extrapolated for the simulations. Obviously, real-world scenarios will have a more complex set of sensor input values, which needs to be addressed in future work.
Originality/value
The simulations show that merely using a streaming platform as a buffer for sensor input values already increases the sensor data throughput and that by applying intelligent filtering in the streaming platform, the actual number of rule executions can be limited to a minimum.

Abstract
Purpose
This paper aims to focus on data analytic tools and integrated data analyzing approaches used on smart energy meters (SEMs). Furthermore, while observing the diverse techniques and frameworks of data analysis of SEM, the authors propose a novel framework for SEM by using gamification approach for enhancing the involvement of consumers to conserve energy and improve efficiency.
Design/methodology/approach
A few research strategies have been accounted for analyzing the raw data, yet at the same time, a considerable measure of work should be done in making these commercially reasonable. Data analytic tools and integrated data analyzing approaches are used on SEMs. Furthermore, while observing the diverse techniques and frameworks of data analysis of SEM, the authors propose a novel framework for SEM by using gamification approach for enhancing the involvement of consumers to conserve energy and improve efficiency. Advantages of SEM’s are additionally discussed for inspiring consumers, utilities and their respective partners.
Findings
Consumers, utilities and researchers can also take benefit of the recommended framework by planning their routine activities and enjoying rewards offered by gamification approach. Through gamification, consumers’ commitment enhances, and it changes their less manageable conduct on an intentional premise. The practical implementation of such approaches showed the improved energy efficiency as a consequence.

Abstract
Purpose
The purpose of this paper is to present a prospective study of sustainable mobility in the framework of a supporting energy management systems (EMS). Technological advances are still required, namely electric vehicles (EV) endowed with improved EMS in order to increase their performance by making the most of available energy storage technologies. As EVs may be seen as a special domestic load, EMS are proposed based on demand-sensitive pricing strategies such as the Energy Box discussed in this paper.
Design/methodology/approach
The study presents an overview of electric mobility and an urban EV project, with special focus on the utilization of its energy sources and their relation with the energy demand of a typical urban driving cycle. Results based on the ECE 15 standard driving cycle for different free market electricity tariffs are presented.
Findings
The analysis based on present Portuguese power and energy tariffs reveals that it is highly questionable whether the resulting profit will be enough to justify the potential inconveniences to the vehicle user, as well as those resulting from the increased use of batteries.
Practical implications
The conclusions indicate that more studies on the trade-offs between grid to vehicle and vehicle to grid schemes and electricity pricing mechanisms are needed in order to understand how the utilization of EVs can become more attractive in the end-users’ and utilities’ perspectives.
Originality/value
The paper proposes an approach for future electricity tariff behavior that could be applied to EVs in order to understand whether or not their grid integration in charge and discharge situations would be beneficial for end-users and utilities, in the framework of smart energy management technologies.

Abstract
Purpose
The purpose of this paper is to examine the future prospects of innovative services linked to sustainable energy systems.
Design/methodology/approach
Service perspective is examined in the context of socio-technical transition and linked to the bottom-up and top-down social processes that foster sustainability. The foresight method applied is trend analysis.
Findings
Two groups of trends were identified: the trends driven by technological development and the trends focussing on societal, managerial and consumer issues. The former consists of renewable energy sources, hybrid solutions, smart grids and smart energy markets. The latter involves distributed energy production, demand response, optimisation of sustainability and the role of energy as an opportunity and as service. The study reveals that energy is increasingly understood as a comprehensive and tailor-made service solution for communities and individual households. Consumers will enter the energy market as active participants; it raises the need for many types of services.
Research limitations/implications
Deepening of understanding is required in several topics of this study, and more formal methods of foresight are needed to test the generalisability of its qualitative results.
Practical implications
More effective policy measures are needed for fostering new services and social and system innovations in the area of sustainable energy. Innovation management practices should be developed in these areas.
Originality/value
The paper aims to narrow the research gap linked to foresight in services by examining services in the area of sustainable energy systems – one of the “grand challenges” today.

Abstract
Purpose
Distribution and retail supply of electricity is the most important cog in the power sector value chain. Despite several reforms, most of the Discoms are facing huge financial losses and resorting to a tariff hike which may not be a viable solution. The purpose of this paper is to analyze a case study of Tata Power Delhi Distribution Ltd (Tata Power-DDL) which inoculated itself against the financial ills, and demonstrates how a utility can nurture itself and manage the key stakeholder expectation with innovation, ethics, safety, transparency and agility being its cornerstone.
Design/methodology/approach
The study analyses the situation for Tata Power-DDL which needs to realign its strategy to meet emerging sustainability challenges. The case covers the aspect of strategic management, strategy formulation and change management system deployment using tools such as strength, weakness, opportunities, threat (SWOT), political economical social technological legal environment (PESTLE), critical success factor and key performance indicator cascade. It touches upon the emerging need for distribution utilities to look beyond economic signals and take social and environmental impacts into the strategy planning process.
Findings
It viewed the distribution business beyond its conventional responsibility of making power available to consumers and to provide quality service. A well thought out adaption and adoption of upgraded technology can be a game changer even for a market which is highly regulated and dominated by players in their respective defined territories.
Research limitations/implications
Since the sector is regulated and each utility has a pre-defined set of area of operation with no competition within its licensed area, hence, there is a limited application of applied strategy tools such as SWOT and PESTLE.
Practical implications
Since the sector is regulated and each utility has a pre-defined set of area of operation with no competition within its licensed area, hence, there is a limited application of applied strategy tools such as SWOT and PESTLE.
Originality/value
India as a market is evolving in energy space and utilities are still struggling to have a fundamental structure to meet the agenda of “power to all.” The paper provides the valuable insights into the process of environmental scanning and formulation of organizational strategy to meet the needs of existing and future energy markets.

Abstract
Purpose
Electricity utilization at electricity peak hour may differ from every single administration region, for example, mechanical region, business territory and residential zone. This paper introduces a demand-side load management (DSM) strategy, which is one of the utilization of smart grid (SG) that is fit for controlling loads inside the residential working so that the client fulfillment is augmented at least expense.
Design/methodology/approach
In this paper, a heuristic algorithms-based energy management controller is intended for a residential region in a SG. Here, Antlion Optimization technique is used for DSM techniques such as load shifting, peak clipping, and valley filling in the residential sectors for 24 h with the help of stochastic function to determine the detection of random distribution of the load.
Findings
This proposed algorithm offered the greatest fulfillment and least expense caused by the consumers when compared to the traditional cost by taking the individual consumer preferences for the loads and the ideal time scheduling for the load, which is obtained from the rebuilding trap.
Originality/value
Simulation results demonstrate that the comparison of the cost incurred by the users obtained by the DSM techniques is satisfiable.

Abstract
The chapter will explore the growth and opportunities of small-scale local power generation and the implications for internet access for rural communities. Solar power has grown exponentially in the last decade across the world and has provided opportunities for the development of local energy communities and on microgrids across the world and in Europe.
The huge cost reductions experienced in solar and its relative mobile and flexible nature have made it a technology perfect for rural areas to develop their own sustainable source of electricity supply. The increasing rise of digital tools has coupled nicely with the advent of mass use of solar in rural areas and thus the connection between smart solar and smart villages has become increasingly a norm.
Rural communities in Europe have embraced solar technology, with many farmers using solar as a means to reduce their electricity costs and also generate new streams of income to improve their overall livelihoods. Some case studies from India, Germany, and Africa will be examined. Other experiences will also be considered, especially where double land use between solar technology and livestock has empowered rural communities.
Outside of Europe, Africa and Asia have also seen solar as a means to electrify remote rural villages. This has lead to the development of microgrids and new technologies that are less deployed in Europe, which are being rolled out for rural communities in the rest of the world. This has been particularly successful in creating smart rural communities as often digital communications have already reached these communities and thus power and telecoms are combining to provide clean and controlled power for millions in Africa. This chapter will also assess the growth of smart energy communities in non-traditional energy markets and determine what lessons we can learn from their experiences.
This chapter will examine other sources of renewable energy and the role that biogas, biomass, and others are playing in the creation of smart villages in Europe and beyond. Biomass has been the traditional tool for many rural communities to generate power and heat and thus an examination of how it now plays a role in smart villages is vital to understanding the energy transition we are experiencing in rural communities.
