“…Getting important opportunities for consumers means also a certain level of responsibility [3,4,5,6]. Therefore, it is obvious that power grids (power supply networks) become intelligent not so much due to the technical equipment, as due to a man and his willingness to organize his behavior accordingly (so that the society could only benefit from it).…”

Abstract. The article reviews the trends which define development of power engineering in the world and in Russia. The authors emphasize that establishment of smart grids is the consequence of not only technological but also social transformations of a modern society. The authors sum up that social competencies are an integral part of professional skills of engineers who work in the field of power engineering. The authors make a hypothesis that the major (educational module) "Energy consultant for the population" might develop social competencies.

Joint Energy Management and Energy Trading in Residential Microgrid System

The sustainability of the power systems assures consumers to have efficient and cost-effective energy consumption. Consumers' energy management is one of the solutions that in fact boosts the power system stability via efficiently scheduling the appliances. In addition to energy management, consumers fulfill their low-cost energy consumption using decentralized energy generation (such as solar, wind, plugin hybrid electric vehicles, and small diesel generator). This decentralized energy generation and its trading among the prosumers and consumers help in the distribution grid stability and continuous supply. In this paper, the joint energy management and energy trading model is presented, which provides low-cost electricity consumption to the distribution system. The proposed framework is a twofold system. In the first fold, the distribution system is divided into a number of microgrids, where each microgrid electricity demand is managed using a unified energy management approach. While the local energy produced is traded among the microgrids in the second fold, through energy trading concepts that fulfill the consumers' demand without stressing the utility company. The results indicate that the proposed model reduced the electricity cost of the microgrids with maximum share of self-generation. Moreover, the results also indicate that each microgrid either fulfills its electricity demand from self-generation or purchases it from the nearby microgrid.

“…The Swedish residential building stock is fairly balanced between smaller and larger residential buildings. The sector consists of two million multi-dwelling buildings and 2,5 million one-and two-dwelling buildings (Bulut et al 2015); 60% of the multi-dwelling buildings are rented from housing companies, 40% of the multi-dwelling buildings are cooperatively owned, and more than 90% are owned by private persons. In addition, there are around 70,000 buildings in the commercial and public sectors.…”

“…Buildings have a high energy demand, and the housing sector uses 40% of all energy nationally (Bulut et al 2015), which translates to roughly 20% of the country's greenhouse gas emissions emanating from the housing sector. Due to this, Sweden has national plans to reduce energy use in buildings by 20% by 2020 and by 50% by 2050.…”

CHAPTER 1: INTRODUCTION The Intergovernmental Panel on Climate Change has shown that stabilizing the increase of global mean temperature below 2°C relative to pre-industrial levels entails a fundamental global challenge (IPCC 2014). With billions of people vulnerable and hundreds of millions at extreme risk from weather-related disasters, climate change poses a great threat to individuals as well as to social and political stability. Climate change has been described by Nobel peace prize winner Wangari Maathai as a "life or death" threat conducted in "a new global battlefield" (Vidal 2009:2). Continuing with business as usual is associated with unfathomable risks and great uncertainties for human life (IPCC 2014). Increased greenhouse gas emissions have been a major cause of the very large late 20th-century warming (Crowley 2000). The sources of these emissions are anthropogenic (i.e., human) activities. The industry sector (especially electricity and heat generation), agriculture, forestry, and other land use industries have contributed two-thirds of global emissions (IPCC 2015). Transportation contributes 14% and buildings contribute 6% of all emissions. In Sweden, 18% of greenhouse gas emissions comes from buildings, an amount equivalent to the transportation sector (Informationscentrum för hållbart byggande 2018). Clearly, a continuation of business as usual in the housing sector is not sustainable. According to leading advocates, a transition to low carbon housing will require very energy efficient buildings on a wide scale, both in developed and developing countries (International Energy Agency 2017). From a climate change perspective, efficient buildings are deemed to be crucial since they lower the overall demand To capture the interrelationships of technical and social elements in the process of mainstreaming, these interrelationships are studied as 'socio-technical' phenomena. A socio-technical perspective entails an approach to the construction and development of buildings emphasizing that technological choices, such as adopting passive house standards and practices, depend on how technologies are embedded in social, political, and economic organizations (Rohracher 2001). This means that institutions and technologies in the housing sector are understood to develop closely in parallel (Nykamp 2017), and advocates of energy efficient buildings adapt their strategies in line with changing social and technological circumstances in the housing sector (Guy & Shove 2000). In socio-technical research, a key interest is how emerging technologies, such as passive houses, co-evolve with institutional change. A study of mainstreaming as situates the thesis within previous research on sustainable buildings in general and passive houses in specific with a focus on socio-technical perspectives. The chapter presents strengths and weaknesses of previous research, how previous research is used, and what this thesis can contribute with in this context. Chapter 4: Theoretical framework presents the theoretical perspective...
