large scale integration of optimal combinations of pv wind and wave power into the Electricity Supply
Renewable Energy, 2006Co-Authors: Henrik LundAbstract:Abstract This article presents the results of analyses of large-scale integration of wind power, photo voltaic (PV) and wave power into a Danish reference energy System. The possibility of integrating Renewable Energy Sources (RES) into the Electricity Supply is expressed in terms of the ability to avoid excess Electricity production. The different sources are analysed in the range of an Electricity production from 0 to 100% of the Electricity demand. The excess production is found from detailed energy System analyses on the computer model EnergyPLAN. The analyses have taken into account that certain ancillary services are needed in order to secure the Electricity Supply System. The idea is to benefit from the different patterns in the fluctuations of different renewable sources. And the purpose is to identify optimal mixtures from a technical point of view. The optimal mixture seems to be when onshore wind power produces approximately 50% of the total Electricity production from RES. Meanwhile, the mixture between PV and wave power seems to depend on the total amount of Electricity production from RES. When the total RES input is below 20% of demand, PV should cover 40% and wave power only 10%. When the total input is above 80% of demand, PV should cover 20% and wave power 30%. Meanwhile the combination of different sources is alone far from a solution to large-scale integration of fluctuating resources. This measure is to be seen in combination with other measures such as investment in flexible energy Supply and demand Systems and the integration of the transport sector.

comparison of carbon capture and storage with renewable energy technologies regarding structural economic and ecological aspects in germany
International Journal of Greenhouse Gas Control, 2007Co-Authors: Peter Viebahn, Joachim Nitsch, Manfred Fischedick, Andrea Esken, Dietmar Schuwer, Nikolaus Supersberger, Ulrich Zuberbuhler, Ottmar EdenhoferAbstract:For the option of ‘‘carbon capture and storage’’, an integrated assessment in the form of a life cycle analysis and a cost assessment combined with a Systematic comparison with renewable energies regarding future conditions in the power plant market for the situation in Germany is done. The calculations along the whole process chain show that CCS technologies emit per kWh more than generally assumed in clean-coal concepts (total CO2 reduction by 72–90% and total greenhouse gas reduction by 65–79%) and considerable more if compared with renewable Electricity. Nevertheless, CCS could lead to a significant absolute reduction of GHG-emissions within the Electricity Supply System. Furthermore, depending on the growth rates and the market development, renewables

Nevertheless, CCS could lead to a significant absolute reduction of GHG-emissions within the Electricity Supply System. Furthermore, depending on the growth rates and the market development, renewables could develop faster and could be in the long term cheaper than CCS based plants. Especially, in Germany, CCS as a climate protection option is phasing a specific problem as a huge amount of fossil power plant has to be substituted in the next 15 years where CCS technologies might be not yet available. For a considerable contribution of CCS to climate protection, the energy structure in Germany requires the integration of capture ready plants into the current renewal programs. If CCS retrofit technologies could be applied at least from 2020, this would strongly decrease the expected CO2 emissions and would give a chance to reach the climate protection goal of minus 80% including the renewed fossil-fired power plants.

towards understanding the benefits and challenges of smart micro grid for Electricity Supply System in nigeria
Renewable & Sustainable Energy Reviews, 2014Co-Authors: Joseph O. DadaAbstract:The poor state of Electricity Supply System in Nigeria is threatening the welfare and security of life and properties of millions of individuals with adverse economic consequences for the country. The inadequacy of the national grid, especially the inability of the Electricity generation capacity to match increasing demand in the country has led to increasing agitation for increased penetration of renewable energy sources (RESs) into the Electricity Supply mix. While great attention has been focused on the potential of RESs for Electricity generation in the country, little or no attention has been given to the application of Smart/Micro-Grid (SM-G) technologies to the ageing Nigeria grid infrastructures and electrification of the rural areas. The aim of this paper is to bring into focus the benefits and challenges of enabling SM-G in the Electricity Supply System in Nigeria. SM-G will bring benefits to the Electricity stakeholders in form of improvements in reliability, efficiency, economics, environment, security and safety. The paper gives an overview and reviews the current state of the Electricity Supply System in the country. It discusses the SM-G concepts and associated technologies, and highlights how they can help address the Electricity problems in the country. The challenges of applying these concepts in Nigeria context are also discussed. Enabling SM-G in the country will not only lead to improvement in the quality, efficiency and reliability of the Electricity grid, but also promote the provision of Electricity Supply to the remote rural areas using RESs.

foreign actors faster transitions co evolution of complementarities perspectives and sociotechnical Systems in the case of indonesia s Electricity Supply System
Energy research and social science, 2020Co-Authors: Akihisa MoriAbstract:Abstract Some low- and middle-income countries go through a transition to a coal-based Electricity System as a way of overcoming the trilemma between energy security, equity, and sustainability. Foreign actors have played a role in addressing bottlenecks in energy transitions and can affect the speed and direction of transition. However, the literature on both the geography and temporality of transitions provides a limited understanding of how different dimensions and layers, as well as domestic and foreign actors, interact and complement each other in the course of transition toward a coal-based Electricity Supply System. To fill this research gap, this paper provides rigorous supporting evidences to the concept of complementarities in the Electricity Supply System, making it operationalize for empirical analysis. The case study of Indonesia finds that transition is hastened by interplay between foreign investors and domestic actors that addresses multiple complementarity bottlenecks in a package. China plays a distinct role among large foreign coal power investors in the transition to a coal-based System by providing both tangible and intangible resources to address complementarity bottlenecks in the crisis period, and in more acceptable terms of conditions to domestic actors who exert power to influence decisions and political goals in their favor.
