As more novel devices are integrated into the electricity grid due to the changes taking place in the energy system, ways of detecting deviations from the intended settings are needed. If misconfigurations of, for example, reactive power control curves of inverters go unnoticed, the safe and reliable operation of the power grid can no longer be ensured due to possible voltage violations or overloadings. Therefore, methods of detection of misconfigurations of said inverters using operational data at transformers are presented and compared. These methods include preprocessing by dimensionality reduction as well as detection by supervised learning approaches. The data used is of high reliability as it was collected in a lab setting reenacting typical and relevant grid operation situations. Furthermore, this data was recreated by simulation to validate the simulation data, which could also potentially be used for detection applications on a bigger scale. The results for both data sources were compared and conclusions drawn about applicability and usability for grid operators.

“…This leaves power distribution system operators (DSO) facing novel challenges. A major cause of these challenges in the transmission and storage of power is rooted in the decentralization of power generation [1]. One of the biggest effects is caused by the widespread use of photovoltaics (PV) in a grid.…”

“…All over the world, there are municipalities that are implementing good examples, setting ambitious climate protection goals, making voluntary commitments to climate protection, hiring their own climate protection managers and consistently working on the implementation of their climate protection concepts [10]. The increasing importance of energy communes, Community-owned energy companies and energy cooperatives worldwide are visible evidence of this phenomenon [11]. The new paradigm of the climate-friendly city has replaced the old paradigm of the car-friendly city from the 1960s and 1970s [12].…”

Schools play an important role in achieving climate protection goals, because they lay the foundation of knowledge for a responsible next generation. Therefore, schools as institutions have a special role model function. Enabling schools to become aware of their own carbon footprint (CF) is an important prerequisite for being able to tap the substantial CO2 reduction potential. Aiming at the direct involvement of students in the assessment process, a new assessment tool was developed within the Schools4Future project that gives students the opportunity to determine their own school’s CF. With this instrument the CO2 emissions caused by mobility, heating and electricity consumption as well as for food in the school canteen and for consumables (paper) can be recorded. It also takes into account existing renewable energy sources. Through the development of the tool, not only a monitoring instrument was established but also a concrete starting point from which students could take actions to reduce Greenhouse Gas (GHG) emissions. This paper presents the tool and its methods used to calculate the CF and compares it with existing approaches. A comparative case study of four pilot schools in Germany demonstrates the practicability of the tool and reveals fundamental differences between the GHG emissions.

“…The establishment of municipal utilities has attracted a lot of attention for several years, not just in Germany [11,12]. A growing number of local governments, politicians and councillors have begun to view their appraisal of municipally controlled and operated utilities as a move towards generating benefits from municipal utilities.…”

“…In Japan, an association was even founded, which is called "Japan Stadtwerke Network". A number of decentralised companies have organised themselves in these, all of which have a special relationship to the municipalities and in which cities often also have a stake [12]. Since the beginning of the millennium, the phenomenon of "(re)municipalisation" marks a global trend for cities to take (sometimes formerly privatised) assets, infrastructure and services (back) into public ownership [14,[18][19][20].…”

More than 150 municipal utilities (so-called Stadtwerke) were established in Germany from the beginning of the millennium, bringing the total number of Stadtwerke currently established within the country to approximately 900. With responsibility for more than half of the supply of electricity, gas and heat in Germany, these Stadtwerke play a central role in the transformation of the energy sector, or Energiewende. In addition, due to their local and regional ties, Stadtwerke have a particular role to play in energy politics, the economy and across society. This article focuses on the motives behind, and grounds for, the current wave of newly established Stadtwerke. Further, it discusses the factors that were critical to the successful formation of new Stadtwerke in recent years. The results of our survey indicate that the establishment of municipal Stadtwerke is a suitable measure to implement the energy transition at the local level, whereby the concept of public value has a high level of importance for the local decision-makers. Collaboration and cooperation, as well as a resilience-oriented strategy, are important success factors for new Stadtwerke.
