Increasing energy prices and the greenhouse effect lead to more awareness of energy efficiency of electricity supply. During the last years, a lot of technologies have been developed to improve this efficiency. Next to large scale technologies such as wind turbine parks, domestic technologies are developed. These domestic technologies can be divided in (1) Distributed Generation (DG), (2) Energy Storage...
In this paper a model for the assessment of efficient energy generation portfolios is presented. The total energy output can consist of multiple energy carriers such as electricity, heat or chemical energy carriers. In order to take into account multiple aspects of performance and different types of incertitude influencing the long-term energy planning process, two different methods are combined....
Following the European Council decision of March 2007, the European Union's common climate protection target for 2020 is a 20% reduction in GHG emissions. In order to acknowledge the related adjustments, opportunities and disadvantages for electricity generation associated with the design of energy policy goals, this paper explores different carbon mitigation policies over the next decades in the...
A novel methodology for economic evaluation of hydrogen storage for a mixed wind-nuclear power plant considering some novel aspects such as residual heat and oxygen utilization is presented in this paper. The simulation of the operation of the combined nuclear-wind-hydrogen system is discussed first, where the selling and buying of electricity, the selling of excess oxygen, and the selling of heat...
The economic evaluation of the microgrids is still challenging. This paper presents a methodology to design the number and capacity for each piece of equipment (e.g. gas engines, batteries, thermal storage tanks) in a microgrid with combined heat and power (CHP) system. In the methodology, annual cost is minimized by considering the partial load efficiency of a gas engine and its scale economy, and...
Multi-generation (MG) solutions to produce for instance electricity, heat and cooling power, are increasing their diffusion, above all on a small-scale basis (below 1 MWe), owing to their enhanced energy, environmental and economic performance with respect to conventional solutions for the separate production of the same energy vectors. Planning of MG systems, including proper equipment selection...
