AbstractNew decentralized energy-generation technologies have turned economies of scale upside down while becoming more economically viable. At the same time, the increased penetration of information technologies has led to new opportunities to manage infrastructure in a less hierarchical, more flexible way. Together with citizen demands for control over energy, these two converging trends has put energy communities (ECs) on the agenda, potentially advancing the transition towards more sustainable energy systems, despite hindrances encountered on the way. This paper presents a case study of the planning process of a sustainable city district in Sweden, using participatory observations and interviews conducted with included stakeholders. We analyse how the included stakeholders has reasoned about establishing a sustainable energy system in the area, including a microgrid. The discussions on a microgrid comprised two parallel discourses, coexisting but seldomly explicitly confronted. The distribution system operator in the area promoted a distributed energy system (DES) solution, while the property developers opted for a microgrid organized more as a citizen energy community (CEC). We discuss why the CEC proponents so far has lost the battle of creating a community owned smart grid. We conclude that the different models, a DES and a CEC, comprise different values and an increased focus on energy communities could shift the transition pathway towards a more decentralized system involving other prioritise than just economical.

Abstract BackgroundNew decentralized energy-generation technologies have turned economies of scale upside down while becoming more economically viable. The increased penetration of information technologies has led to new opportunities to manage infrastructure in a less hierarchical, more flexible way. Together with citizen demands for control over energy, this has put energy communities (ECs) on the agenda, potentially advancing the transition towards more sustainable energy systems, despite hindrances encountered on the way.This paper presents a case from Sweden, using participatory observations and interviews conducted during the planning of a sustainable city district built around sharing. We examined the discussions between stakeholders concerning smart energy systems and the establishment of a microgrid.ResultsWe found that the discussions of the microgrid comprised two parallel discourses, coexisting but seldomly explicitly confronted. The distribution system operator in the area promoted its solutions, while the property developers opted for a microgrid organized more as an EC. We discuss why the EC proponents apparently lost the battle in this smart grid case.ConclusionsThis paper described the energy planning process in a case study in Sweden, where two different models for building an electric microgrid can be identified: distributed energy systems and energy community perspectives. We suggest that these perspectives have different values. We conclude that interest in microgrids could shift the transition pathway towards a more decentralized system involving a variety of owners.

The concept of an autarky has a long history and meaning related to its negation and unpopularity. In liberal schools of economics, autarky is usually considered from the perspectives of economic trade protectionism, closed economies, and threats to welfare. Nevertheless, the concept of autarky has gained a new meaning, understood as the local utilization of renewable energy resources from the perspective of their inter- and intragenerational distribution. Local action is shaped by the global perspective. This research consists of three steps. First, a model of energy autarky has been offered based on the system theory. The model shows the variety of the structures and features of energy systems offered in today’s debates on energy autarky. Second, the key postulates of sustainable development have been presented to define an autarkical sustainable energy system. Finally, the concept of bioenergy villages in Germany has been presented to illustrate the approach to energy autarky. The research shows that the concept of autarky and single solutions, such as the use of renewable resources, are not themselves a success from the perspective of sustainable development; this misunderstanding is well illustrated by the evolution of the German concept of bioenergy villages into smart villages.

AbstractWith the continued growth of renewable energy technologies, major changes are under way in a growing number of energy systems across the globe. Wind, solar, biomass, hydroelectric and geothermal solutions experience an impressive boom and have created a new business sector worth US$243 billion in 2011. This trend is not caused by recent breakthroughs in engineering; in fact most of the technology has been around for some time. The way we organize our energy infrastructure is not primarily a technical matter; it is above all a political decision. The scale-up of renewable energy supplies at the cost of today's fossil-fuel dominated energy infrastructure is a systemic transition from one technology regime to another and thus requires political leadership for setting the targets, guiding institutional change, freeing resources and deciding on the relevant regulations. Today's energy systems are based on well-established routines and – as any other existing societal arrangement – are governed by a certain degree of lock-in: because people are generally happy to do things the way they have done it in the past, they are unlikely to embrace change quickly. These “lock-ins” shape, to a large extent, the speed of change as well as the type of solutions required in order to leave behind what works for today in favor of what we want to work for tomorrow. This article provides an overview of recent developments in the energy systems in Germany, California and Japan. We show that in order to appreciate the dilemma's that arise when creating a more sustainable energy system, we need to understand the local political landscape and how it influences decision-making processes. Looking at the three regions, it becomes evident that the level of political leadership determines much of what technology can do to facilitate innovation in the field of sustainable energy.

Distributed Energy System

Due to the coupling of different energy systems, optimization of different energy complementarities, and the realization of the highest overall energy utilization rate and environmental friendliness of the energy system, distributed energy system has become an important way to build a clean and low-carbon energy system. However, the complex topological structure of the system and too many coupling devices bring more uncertain factors to the system which the calculation of the interval power flow of distributed energy system becomes the key problem to be solved urgently. Affine power flow calculation is considered as an important solution to solve uncertain steady power flow problems. In this paper, the distributed energy system coupled with cold, heat, and electricity is taken as the research object, the influence of different uncertain factors such as photovoltaic and wind power output is comprehensively considered, and affine algorithm is adopted to calculate the system power flow of the distributed energy system under high and low load conditions. The results show that the system has larger operating space, more stable bus voltage and more flexible pipeline flow under low load condition than under high load condition. The calculation results of the interval power flow of distributed energy systems can provide theoretical basis and data support for the stability analysis and optimal operation of distributed energy systems.
