Publish or perish is a crucial rule of life in researchers carriers, same for PhD students as well as for senior researchers searching for research funding. It may be especially difficult to publish first paper in a leading journal, since apart from having some really exciting research results, writer must also know how to present it properly, while taking into account also the research community around the particular journal.
Often submissions get rejected only because a proper literature review is missing, or if methodology and results are mixed throughout the paper, not allowing the methodology to be reused for some other but similar case study. Authors often only cite those references that have been used to reach the results, but forget to cite all those other similar work, especially in the immediate topic of research, which will show that their results are truly a new contribution.
The panel made of editors-in-chief of leading partner journals to the SDEWES Conference, will try to highlight what are the most important things that authors have to take into account when submitting their papers to journals.

Due to globalization of the R&D and science in general, and global acceptance of the new criteria for promotion of young researchers and croiteria for PhD studies (citation index, number of citations, publishing in journals with high Impact factor), it can be noticed great changes in charactes of submitted and published archival papers. Presentation will discuss those changes, and influence of the enormous number of papers on the quality of papers, choice of subjects and character of the scientific papers.
Changes in origin of the authors are also evident. Authors from Asian countries are in majority, irrespective if they are working in their countries or in Western countries. Also, relation between large world well known journals and publishing houses, and small journal from developing countries will be discussed (including dilema - OPEN ACCESS journals or not).
In many cases, research within sustainable energy, water and environmental systems is based on the use of simulation models or similar. Often such models are comprehensive and complicated to describe, understand and communicate as well as to verify and validate. Furthermore, a full description typically cannot be included in a scientific paper. At the same time, most journals expect some kind of validation in terms of e.g. sensitivity analysis or similar. Often such an expectation is implicit based on the positivist/objectivist scientific belief that a model can either be wrong or right. However, the case is far from that simple for comprehensive energy, water or environmental simulation models. The presentation discusses the principle problem of validation of models with reference to different scientific understandings and it sketches a simple pragmatic guideline for how to deal with this problem for authors as well as reviewers and editors. Moreover, the guideline is illustrated by a case.
The publication of archival papers requires credible research results, however this is just first step.
Several further issues should be considered:
• Why I am writing a paper?
• Just because I need two papers for PhD?
• A paper should be
- Based on a piece of reasonable work
- Carry a message about my research results
- Make sense and fit the context
- Some use to the other researchers
Where to get some guidance?
• Many good English speaking universities are offering wed based tutorials
• However those advises are mostly rather general
Steps In Writing The Research Paper
• 1. Choose your subject
• 2. Narrow your subject
• 3. Provide a focus for narrowing material
• 4. Find references and select bibliography
• 5. Gather notes
• 6. Categorize notes
• 7. Decide upon an approach and point of view to gain control over your material
• 8. Draw up a detailed outline
• 9. Write a detailed outline
• 10. Make a clear copy
• 11. Leave for a day
• 12. Edit your work - go over you paper four times
More specific advice
• Ask more or well experienced colleagues
• The more experienced is the person the better
• Experience with the right field and journals
• Editors and reviewers are most valuable to get the right information
• The most valuable is personal experience – try it by yourself
The contribution to the panel should facilitate discussion about this and some other issues, which young researchers need to master to be successful authors
100 % electricity supply by renewable energies is content of several scientific studies and aim of communities, regions, or even countries. The role of “smart grids” is often used as a mean to achieve this aim. Whereas the first 50 %, 60 % or even 80 % seem to be achievable with not too high expenditures, the 100 % aim seems to become very costly and technology approaches are required reaching far beyond of nowadays state-of-the-art. It is discussed whether we will require transnational and even transcontinental so-called overlay grids in order to distribute electricity adequately. Or it is discussed that we then require immense electricity storage capacities.
Broadening the perspective towards the complete energy supply – not only electricity – but also supply with heat and cold and including transport sector the 100 % aim not necessarily becomes more difficult and more complex but synergies might evolve supporting the aim to be reached easier than a separate consideration of historically separated energy supply chains. The panel will discuss these synergies and approaches in different countries will be discussed.

The design and concept of Smart Energy Systems is crucial for large scale integration of renewable energy and in particularly in 100% renewable energy and transport systems. 100% renewable electricity systems has been analysed and shows that electricity storage systems of various kind become necessary. This however is introducing unnecessary losses into the system. The need to integrate other sectors of the energy system and to have a more holistic approach becomes crucial.
In energy systems with an increasing penetration of intermittent renewable energy in the electricity grid, the demand for integrated systems increases. Smart Energy Systems are comprised of infrastructure which is significantly different from the infrastructure and design of today. It is not only comprised if electricity smart grids and the supply/demand for electricity. It can accommodate sector integration and the use of distributed renewable energy sources as well as efficient distributed integration of renewable energy. The integrated approach opens up for the use of many more renewable energy resources than single sector focuses does.
Smart Energy Systems are comprised of a number of smart grid infrastructures for different sectors in the energy system such as electricity grids, district heating and cooling grids as well as fuel infrastructure. Along with this there are a number of short term and longer term storage options. The gas grids and liquid fuels allows for long term storage while batteries in electric vehicles and heat pumps and thermal storages in district heating systems allows for shorter term storage and flexibility using the district heating and electricity grids.
The Smart Energy System concept enables a flexible and fuel efficient integration of large amounts of fluctuating renewable energy into the electricity, heat and transport sectors, and enables societies to unlock the dependence on bioenergy based or fossil fuels. It also enables a pathway to reduce the necessity to use biomass at all in the longer term. The Smart Energy System concept enables an intelligent use of potential carbon sources and can bridge such systems from today over an intermediate biomass based economy to a carbon and renewable energy based economy.
The electrical energy supply chain globally is undergoing a radical transformation, driven on one hand by the challenges of climate change associated with anthropogenic activities, natural disasters, and energy security, and on the other by major innovations in technology. This transformation can be seen in the changing power generation portfolios and wholesale electricity market structures, as well as the rapid rise of renewable resources–mainly wind and solar. In Europe, these changes are driven by the overarching European Union target to reduce greenhouse gas emissions by 20% below 1990 levels, to improve energy efficiency by 20%, and to increase the proportion of final energy consumption from renewable sources by 20%, all by 2020. This is the so-called ‘20‐20‐20 by 2020 target.’ A key and necessary enabler for this transformation in the electrical energy supply chain is innovation and radical changes in policy, social, and corporate acceptance, technological advancements and a revamp of so‐called ‘liberalized’ electricity market structures. This presentation will discuss these ‘enablers’ and look far beyond 2020 with an eye to deliver massive carbon reductions by 2050, ultimately identifying some of the possible pathways to achieving the panacea of a totally carbon-neutral society.
The upcoming eMobility requires new concepts for recharging infrastructures. Such infrastructures are mainly needed in urban areas because of reduced vehicle operating range and comparatively long recharging time periods. That way, first customers for electric vehicles or plug-in-hybrids will be citizens or companies in larger cities. Offices of inner-city companies are predestinated to replace their conventional vehicle feet by new electrified vehicles. However, arising mobility costs would not be reduced that way. One solution is to use renewable energy for vehicle recharge. This way, renewable energy production has to be integrated in the installed recharging infrastructure.
But, what is the best configuration for the required renewable energy system in case of an office building? Besides electric energy supply for vehicles also building’s electricity as well as heat demand has to be fulfilled. Furthermore, energy is not always needed when it can be locally produced by renewables. That way, further storage systems have to be integrated in an appropriate concept.
Therefore, EA Systems developed its Modelica-based ‘Green Building’ simulation library which includes physical models for renewable energy systems, buildings, storages and energy consumption. That way, complete building energy systems also including charging stations for eVehicles and plug-in-hybrids can be modeled. Simulating their behavior depending on different weather conditions as well as usage and mobility scenarios allows overall system evaluation regarding overall system costs, renewable energy share and ecological footprint.
This paper presents concept of ‘Green Building’ library combining renewable energy system and vehicle simulation. Results of system simulation and evaluation for an exemplary office building including a fleet of 10 eVehicles are shown as well to depict universal applicability of presented simulation approach.
