This volume present research on overall national energy planning development with a case from Nigeria. This is followed up by a sustainability assessment of nine sample countries. Moving on to the more local scale, potentials and barriers for photo voltaic systems with cases from Germany, Nigeria and Tanzania are presented. Finally, analyses focusing on the spatial dimension of energy system are presented. This last part addresses both the delimitation between rural and city energy systems and how they should combine and the optimal design of district heating systems.</p> 2019-07-07T00:00:00+02:00 ##submission.copyrightStatement## https://journals.aau.dk/index.php/sepm/article/view/2435 Energy modelling as a tool for curbing energy crisis and enhancing transition to sustainable energy system in Nigeria 2019-05-21T19:32:42+02:00 Ahmad Garba Khaleel 2015017696.ahmad@dr.sharda.ac.in Milindo Chakrabarti milindo.charabarti@sharda.ac.in <p><em>The relevance of energy in the growth and development process necessitate giving serious attention to the planning, production and consumption of energy. This is usually referred to as energy planning and analysis or modelling carried out in recent years using sophisticated and computerized models. These models rely heavily on future assumptions regarding the expected economic conditions in consideration to the current and unfolding situations of the economies in question. However, due to uncertainty of the future economic conditions of especially developing economies, these assumptions are mostly found unable to adequately capture the evolving events. This is more evident if one looks at the alternative energy projections made by different organizations using different understandings and assumptions. This study compares the best electricity demand and supply projections of NECAL2050 as the best energy model in Nigeria and other alternatives projections by </em><em>[6, 13,] and previous Energy Commission of Nigeria - ECN’s energy models by [14]</em> <em>to show case the discrepancies and their economic consequences. Policy implications and recommendations are discussed at the end.</em></p> 2019-05-21T00:00:00+02:00 ##submission.copyrightStatement## https://journals.aau.dk/index.php/sepm/article/view/2628 Barriers and motivations for solar photovoltaic (PV) adoption in urban Nigeria 2019-05-21T19:32:40+02:00 Anthony Ifeanyi Ugulu anthonyugulu@yahoo.com <p>For decades, Nigerian households have endured unreliable national electricity supply which have stifled economic growth and socio-economic development. As nations shift to green electricity adoption and a commitment to lowering their carbon footprint, opportunities arise for developing countries like Nigeria to improve supply using solar PV for power generation. At over 50% private power systems ownership, the majority of urban Nigerian households rely on self-generation using expensive petrol and diesel-powered generators. With PV generated electricity increasingly becoming more cost-competitive with conventional sources due to technological learning and support policies, this paper investigates the barriers to and motivations for PV adoption in urban Nigeria. Using interviews, data were gathered on key barriers to and motivations for PV adoption and results analysed. Findings indicate that the major barriers are high capital costs and lack of finance. The key motivation for PV adoption was power outages, energy cost-savings including generator use fuel fraud, awareness and access to finance. The results point to the need for regulatory and political intervention. Effective PV awareness creation campaigns and promotional strategies would also be necessary in the changing face of electricity supply in Nigeria.</p> 2019-05-21T14:25:58+02:00 ##submission.copyrightStatement## https://journals.aau.dk/index.php/sepm/article/view/2890 Coupling heat and electricity storage technologies for cost and self-consumption optimised residential PV prosumer systems in Germany 2019-05-21T19:32:41+02:00 Dominik Keiner dominik.dk.keiner@gmx.de Christian Breyer christian.breyer@lut.fi Michael Sterner michael.sterner@oth-regensburg.de <p>Coupling energy sectors within the emerging residential PV prosumer systems is necessary for an optimised use of the houseowners’ own produced electricity. But the pure availability of different energy technologies in the system is not enough. By optimising the electricity usage as well as the capacities of PV generators, storage technologies, heat pumps and battery electric vehicles, not only the best solution in a technical point of view can be achieved, the need of finding the most financially beneficial system composition for single-family houses and tenements is possible. The study provides a detailed model for average German single-family houses and tenements and results for the energy transition period until 2050 for the optimised energy systems regarding optimised PV and stationary battery capacities and different heat storage capacities. Most noticeable outcomes can be observed by using a vehicle-to-home car, where a car can mostly take over the tasks of a stationary battery and by introducing a solidarity model using this type of car in tenement systems.</p> 2019-05-21T14:25:15+02:00 ##submission.copyrightStatement## https://journals.aau.dk/index.php/sepm/article/view/2721 Energy sustainability indicators based on UN goals and Urban themes to measure energy sustainability for developing countries using SEDIInvestigating energy sustainability indicators for developing countries 2019-07-10T19:39:25+02:00 Ali Armin Razmjoo arminupc1983@gmail.com <p>The study is an attempt to identify and apply a set of energy sustainability indicators by policymakers and energy experts as a suggestion for the developing countries. Also, this paper presents an analysis of sustainable energy development index (SEDI) between 10 developing countries. Actually, this study shows a relative situation of energy sustainability for 10 developing countries in different areas of the world. At first, will gather required data for four years and belongs to 2012 until 2015 years from IEA and world bank data organizations and then will analyses them, and at the final, the SEDI ranking of each country will be obtained. Results show that in comparison with past years, all studied countries intend to achieve a remarkable growth in energy sustainability. Selecting the SEDI method in this work has two main causes; firstly, this method has multidimensional attention to energy sustainability and secondly can be a good method to find strong and weak indicators for a country.</p> 2019-07-10T12:27:24+02:00 ##submission.copyrightStatement## https://journals.aau.dk/index.php/sepm/article/view/2663 A combined spatial and technological model for the planning of district energy systems 2019-07-22T19:41:25+02:00 Kamal Kuriyan k.kuriyan@imperial.ac.uk Nilay Shah n.shah@imperial.ac.uk <p class="Els-body-text"><span lang="EN-US">This paper describes a combined spatial and technological model for planning district energy systems. The model is formulated as a mixed integer linear program (MILP) and selects the optimal mix of technology types, sizes and fuels for local energy generation, combined with energy imports as required, and exports of any excess energy. The model can also be used to select the locations for the energy sources, the distribution route, and optionally, to select the heat loads that will be connected to a district energy system. The optimisation model combines a map-based spatial framework, describing the potential distribution network structure, with a flexible Resource Technology Network (RTN) representation which incorporates multiple heat sources. Scenarios can be formed for different price levels for delivered heat or electricity, combined heat and electricity demands, and different technologies and fuels for heat generation. Results for scenarios based on a synthesized test dataset are presented. The results illustrate how the model may be integrated within a map-based decision support tool for urban planners. The paper also introduces a system value metric to quantify the incremental impact of investments in the heat network.</span></p> 2019-07-22T18:50:09+02:00 ##submission.copyrightStatement##
