| 1 | Possible role of power-to-heat and power-to-gas as flexibleloads in German medium voltage networks显示文摘Germany's energy transition triggered a rapidand unilateral growth of renewable energy sources (RES)in the electricity sector. With increasing shares ofintermittent RES, overcapacities during periods of strongwind and photovoltaic electricity generation occur. In theface of insufficient transmission capacities, due to aninhibited network extension, the electricity generation hasto be curtailed. This curtailment of RES leads to economiclosses and could be avoided through flexible loads. As anoption to cope with those problems, the technologies ofpower-to-gas (PtG) and power-to-heat (PtH) are presentedin this paper. First, the alkaline electrolyzer (AEL),polymer electrolyte membrane electrolyzer (PEMEL),and solid oxide electrolyzer cell (SOEC) are investigatedregarding their operational parameters. Second, the electricboiler, electrode heating boiler, and heat pumps areconsidered. Ultimately, the network-supporting abilitiesand the potential to provide ancillary services, such ascontrol power, load sequence operation, cold start and partload capability, are compared among one another. | Mark KUPRAT Martin BENDIG Klaus PFEIFFER | 2017 | Frontiers in Energy2017，11，2： | 2 |
| 2 | Integrated energy in Germany-A critical look at the development and state of integrated energies in Germany显示文摘In the face of global warming and a scarcity of resources,future energy systems are urged to undergo a major and radical transformation.The recognition of the need to embrace renewable energy technologies and to move toward decarbonization has led to significant changes in the German energy generation,consumption and infrastructure.Ambitious German national plans to decrease carbon dioxide emissions on one side,and the unpredictable and volatile nature of renewable energy sources on the other side have elevated the importance of integrated energies in recent years.The deployment of integrated technologies as a solution to interlink various infrastructures creates opportunities for increasing the reliability of energy systems,minimizing environmental impacts and maximizing the share of renewable resources. This paper discusses the role of integrated energy systems in supporting of sustainable solutions for future energy transitions.Moreover,the reinforcement of this movement with the help of different technologies will be discussed and the development of integrated energy systems in Germany will be reviewed. | Saman AMANPOUR Daniel HUCK Mark KUPRAT Harald SCHWARZ | 2018 | Frontiers in Energy2018，12，4： | 1 |
