The intermittency of renewable energy sources, e.g. wind or solar, as well as forecast uncertainties in load, price and renewable infeed profiles call for storage solutions and appropriate control strategies. For the investigations in this paper the energy hub modeling framework is used, which takes into account multiple energy carriers, distributed generation, energy storage systems and renewa...

Global economic growth is accompanied by increased energy demand, thus conventional fuels such as coal, oil and gas, which are the primary sources, gradually being depleted. At same time, combustion of fuel for production causes serious adverse effects on environment contributes to climate change due emitted greenhouse gases. For above reasons, most developed developing countries especially dur...

The probably biggest challenge for climate change mitigation is to find a secure low-carbon energy supply, which especially is difficult as the supply of renewable sources underlies strong volatility and storage possibilities are limited. We therefore consider the energy sector of a small country that optimizes a portfolio consisting of fossil and/or renewable energy to cover a given energy dem...

A combination of series, parallel and multilevel power electronics has been investigated as a potential interface for two different types of renewable energy sources and in order to reach higher power levels. Renewable energy sources are typically dispersed in a territory, and sources, like wind and solar, allow small to medium-scale generation of electricity. The configuration investigated in ...

This paper proposes a stochastic optimization model for the day-ahead scheduling in power systems, which incorporates the hourly demand response (DR) for managing the variability of renewable energy sources (RES). DR considers physical and operating constraints of the hourly demand for economic and reliability responses. The proposed stochastic day-ahead scheduling algorithm considers random ou...

The International Renewable Energy Agency (IRENA) is an intergovernmental organisation dedicated to renewable energy. In accordance with its Statute, IRENA's objective is to "promote the widespread and increased adoption and the sustainable use of all forms of renewable energy". This concerns all forms of energy produced from renewable sources in a sustainable manner and includes bioenergy, geo...
