Non-linear modelling of integrated energy supply and demand systems
An approach to energy systems modelling is presented. It employs a mixture of non-linear programming techniques considered suitable for the particular structure of energy models, in order to overcome the problems encountered in optimisation with a non-trivial objective function topology, e.g. with several local minima. Preliminary results for a European energy model are presented.Keywords: energy ...

Learning curves and technology assessment
This paper uses the formal concept of learning curves to analyse regular behaviour of performance improvements in various energy technologies. The concept allows the estimation of a single indicator of technological progress, the learning rate, which expresses the constant percentage improvement (usually in terms of cost reductions) in a technology for each doubling of the technologies cumulative ...

Modelling energy technology dynamics: methodology for adaptive expectations models with learning by doing and learning by searching
This paper presents a module endogenising technical change which is capable of being attached to large scale energy models that follow an adaptive-expectations. The formulation includes, apart from the more classical learning by doing effects, quantitative relationships between technology performance and R&D expenditure. It even attempts to go further by partially endogenising the latter by ...

Model-based decision support in energy planning
Models have become standard tools in energy planning. Fast computers and ever improving optimisation packages now allow us to solve problems within a few minutes that were out of range 20 years ago and that 10 years ago could only be solved in several CPU-hours. Fully interactive data bank systems with standardised user interfaces and on-line data access support easy modifications and adaptations ...

Applications and limits of theoretical adsorption models for predicting the adsorption properties of adsorbents
The objective of this study is to evaluate the applicability of adsorption models for predicting the properties of adsorbents. The kinetics of the adsorption of NO3− ions on a PP-g-AA-Am non-woven fabric have been investigated under equilibrium conditions in both batch and fixed bed column processes. The adsorption equilibrium experiments in the batch process were carried out under different ...

Decision support system framework of the PRIMES energy model of the European Commission
PRIMES is a large scale model of the energy systems of European Union member-states linked together through energy markets. The PRIMES software is based on a full-scale decision support system (DSS) framework, which is presented in the paper. The DSS framework of PRIMES intends to support the seamless integration of data management, model running and reporting. The system is based on a common ...

The treatment of technology development in energy models
The paper addresses some key issues in the application of projections for technology development in models used to analyse large-scale energy systems. Examples of technology development in the electricity and transport industry are used to illustrate the difficulties. It is suggested that projections should be obtained from uncommitted sources and standard assessment criteria used. Factors in ...

A new approach to energy modelling: the SE³T system and its multi-objective integrated methodology
Based on the complex system theory, this paper extends the current notion of the Energy-Economy-Environment (3E) model and establishes a theoretical framework for the Society-Economy-Energy-Environment-Technology (SE³T) complex system. The components and structure of SE³T are described, as well as its relationships among its subsystems. The corresponding modelling method, integrating the idea of ...

Decision analysis under uncertain CO2 regulation policies with a global energy model and its implication for power system planning
Global warming caused by the increase of atmospheric CO2 concentration is regarded as a serious environmental issue. Due to uncertainty relating to the mechanisms of the terrestrial carbon cycle and climate system, solution of the problem is considered to be extremely complicated. In such a context, to conduct a decision analysis under uncertain CO2 concentration control policies, we have ...
