This article investigates how biogas technology can facilitate the deployment of municipal circular bio-economic solutions within the energy and agrarian sectors in Denmark. The emphasis is on the regional climate policy and the existing biogas technology concepts, within a decentralized energy market located in the Southern part of Zealand. The case analysis will identify how such technology can be utilized as a lever for future “extraction-activities,” as for example protein, wax, and furfural substrates. Within Falster & Lolland Municipalities, it is identified that 800.000 tons of animal manure is readily available for biogas production, just as 880.000 tons and 220.000 tons of unused beet tops and residual cereal straw could be feed to biogas facilities as for example co-silage materials. With a potential gas yield of approximately 897.000 MWh, composed by the crop residues alone, the challenge is how to utilize such resources the most efficient when addressing future needs for bio-products and high value materials and energy. Through the lens of Circular Bio-Economy this article addresses three themes, by which biogas technology can become an “engine” for future bioenergy solutions, where cascading activities and use of side-streams are developed: 1) production of biogas by means of local agricultural residues (beet tops, residual straw, and animal manure), combined with 2) “extraction-activities” as furfural and wax from straw, as well as protein from beet tops. Besides this 3) opportunities for upgrading the biogas and distributing it on a natural gas network, hereby enlarging the supply market for energy services from the biogas plant and facilitating the development of a more “integrated energy system,” currently being promoted by the European Commission. This article concludes on a step-by-step approach to utilize biomass residues more efficiently in light of the CBE concept and cascading approach, and the available biomass resources within the specific case area addressed.

 Aim: This study examines the impact of governance on decentralized energy transitions. Knowledge of how particular jurisdictions and their governance arrangements influence these transitions can help strengthen and contextualize divergent trajectories of decentralized energy transitions and—most importantly—reveal the role of geographical context in policy change. Design: This research gap is addressed in this paper by comparing the uptake of decentralized energy transitions in three cities in three different countries—Luleå (Sweden), Saskatoon (Canada), and Anchorage (United States). The jurisdictions in each city has unique governance contexts pertaining to electric utilities, regulations, public policy, and public acceptance.  By comparing these transitions, this study highlights the governance considerations for decentralized energy transitions and asks how does governance impact decentralized energy transitions in cities? To answer this question, actors within various public, private, and sectoral capacities were interviewed to provide their insights on decentralized energy transitions in each jurisdiction. Conclusion: I present five governance dimensions that impact decentralized energy transitions and explain how these factors can be included to provide a more contextual understanding of patterns of decentralized energy transitions in cities.  Originality: Much of the literature on decentralized energy and cities has focused on project and sectoral level analysis and hasn’t considered the holistic nature of the energy system transition. A particular gap that would help inform a broader understanding is the jurisdictional governance impacts of decentralization energy transitions. Implications of the Research: In practical terms, the results could be used to inform inter-jurisdictional comparisons of decentralization energy projects. Limitations of the Research: Given that there were three case studies, it is not possible to make generalizable claims from the results.  


A solar-wind hybrid system plays a key role in power generation and becomes very important role to smart grid power systems. Also, the wind-solar hybrid energy storage control systems in coordination of energy markets, made economical to the electrical power system power system. Hybrid renewable energy system connected micro-grid consists of significant identification; in view of solve the rising electrical energy demand. In addition to this the problem of harmonic distortion in micro-grids due to the non-linear loads is an indispensable topic of study. Also, it is very significant for the better understanding of the power quality impacts in micro-grids. This paper presents detail analysis of different control techniques for optimization of harmonics in smart grid system and enhancement in power quality of the smart grid system. The performance of the control system is verified through the MATLAB simulation of the hybrid solar-wind electrical energy system.

In the development of smart grid solutions, the contribution of industrial consumers is prime essential to ensure the energy system transformation. The present article introduces a covenant with the implementation of an economic dispatch (ED) in the electrical framework with the smart grid. The proposed ED strategy is comprised of two steps; the first step includes the swarm optimization technique of energy ED with the net loss of the power system and the second step consists of an ED that considers the cutoff points of system security. The prime goal of the second step is to minimize the net loss and the foundation development of the generator cost function. The test framework is comprised of four generators with one battery storage apparatus that considers the energy demand. The ED will perform for 24 hours. The test results show that the two-step ED technique not only reduces system losses but also the fuel consumption of the system as well. This article gives ideas to the industrial consumers to implement a smart grid in the industrial sector.
