Remaining useful life (RUL) is of great importance to energy supply systems, such as battery pack. In this paper, an optimization model of RUL for the paralleled battery pack on expansion mode is proposed based on the basic concept of RUL and the capacity fading model. genetic algorithm (GA) is adopted to solve the problem. Case study shows that the battery pack's RUL can be extended by using the optimization model and GA.

AbstractIn closing his 2008 Myer Lecture, the scientist and environmentalist Dr Tim Flannery said that this century will be defined by the search for sustainability. How perilous therefore that nowadays there is so much overuse of the word “sustainability” that it has become a cliché. Today's tertiary students studying architecture and energy-related subjects are so exposed to this linguistic devaluation that most of them appear to have accepted the vagueness of the term and are on their way to becoming the next generation of misusers. This paper presents a case study of an attempt to sharpen up the debate with some university students from these particular disciplines. A model of the four principles of sustainable development that has been found to be particularly useful is described. The students in question were challenged to think about the meaning of some of the words ascribed to new buildings and about the implications of the four principles to energy supply systems.

Energy Supply Systems

One of the new challenges arising from the transition of the energy industry to the path of intelligent development is to assess the effect of distributed generation (DG) on the prospects for the development of regional energy supply systems. Such an assessment requires that the factors characterized by high uncertainty be taken into account. In this case, it is expedient to employ a combination of the optimization method with the Monte Carlo method. Such an approach has already been adopted in a model (computer program) developed at the Melentiev Energy Systems Institute, Siberian Branch of the Russian Academy of Sciences. This model is designed to determine the rational mix of new power plants (with investment risks assessed and factored in) and the likely cost of electricity generation in a given aggregated region. We propose using this model as a source of projected data for an approximate assessment of the DG expansion, given the projected conditions for the energy sector and electric power industry development. It may also provide the basis for an array of research tools for relevant studies. The new toolkit requires a more detailed representation of the administrative division and the inclusion of consumers with their sources of electric power generation in the generating capacity. Although such an estimate is approximate, it can give an overall idea of the extent to which the cost and demand for electricity may vary under different options for the DG expansion in a region.

Energy Supply Systems

An energy supply system consists of a system of power plants and transmission anddistribution systems that supply electrical energy. The present project is limited to the modellingof the generation system. Its objective is the design and implementation of a web-basedapplication for simulating energy supply systems using the Laravel framework. The projectfocuses on six modules representing geothermal energy, solar energy, biopower, hydropower,storage, and fossil-based energy that are allocated to satisfy a given power demand. It isexecuted as a time series modelling for an exemplary year with hourly resolution. Thedevelopment of the software is divided into four steps, which are the definition of the userrequirements, the system design (activity, use case, system architecture, and ERD), the softwaredevelopment, and the software testing (unit testing, functionality testing, validity testing, anduser acceptance testing). The software is successfully implemented. All the features of thesoftware work as intended. Also, the software goes through validity testing using three differentinput data, to make sure the software is accurate. The result of the testing is 100% accuracy withrespect to the underlying model that was implemented in an excel calculation.
