This paper illustrates an analysis of the power generation expansion plan of the Hellenic Interconnected Mainland System as an aspect of the National Renewable Energy Action Plan (NREAP) of the country for the year 2020. The modeling background and a description of the incorporated technologies are thoroughly provided. In addition, major conclusions of the scenarios investigated are analyzed, and...
In full knowledge of the energy-saving and emission reduction (ESAER) policies in China, it is analyzed in this paper what the promising new futures in electricity demand in East China in the context of ESAER. To propose the well applicable load forecasting methods for East China power grid, where the ESAER policies have being intensively implemented since 2005, the reality of economic development...
Thailand currently relies largely on natural gas, coal & lignite, fuel oil, and less portion in renewable energy for electricity production. Due to the cheap fuel costs, fossil fuels dominate in energy supply. However, utilization of more fossil fuels results in increasing CO2 emissions. The introduction of carbon dioxide capture and storage (CCS) for the future thermal power plant in Thailand...
Existence of market power in electricity markets has been revealed by extensive studies, however, the understanding of how environmental policies, e.g. emission trading scheme, impacts on the change of market power of generation companies (GENCOs) is at the inchoate stage. This paper, targeted at the study of Australia National Electricity Market, presents the Cournot market equilibrium model incorporating...
Public policy in the U.S. and Europe has sought to control several major pollutants from power plants through a cap-and-trade system, whereby a secondary market is established for emissions permits. The costs of these emissions permits are a variable cost of power production and are thus integrated into regional electricity markets and locational wholesale electricity prices. Exposing retail consumers...
Electric vehicles (EVs) offer the possibility of electrical energy storage within the power grid on low voltage level. By means of controlled off-peak charging of the EVs' batteries, it is thus possible to cover the power demand of several million EVs without the need for additional power plant capacities. In effect, electricity can thus be supplied at a very cost-effective rate. A simulation of Germany's...
There is a growing consensus that the great risks arising from climate change require strong cuts of greenhouse gas emissions and that actions are urgently needed. The current economic crisis force policy makers to reconsider their policies and to introduce reforms that foster enhanced efficiency and more sustainable long term growth. Within this context, this paper assesses, by means of a scenario...
For a long time, China's coal-based energy structure, as well as thermal-power-led power structure, has caused serious environmental pollution problems. To achieve the emissions constraints of major pollutants till the end of Eleventh Five-Year Plan, and optimize China's power structure, the research builds the electricity production and environmental constraints coupling optimization model and proposes...
Carbon dioxide has been identified as a major greenhouse gas responsible for a large part of the enhancement of global warming. CO2 capture and storage (CCS) from power plants is drawing increasing interest as a potential method for the control of greenhouse gas emissions. Technically, the capture of CO2 from the flue gas of power plants, using a monoethanolamine (MEA) absorption process is a viable...
Models based on complementarity formulation have been a useful tool to simulate the interactions between environmental policies and the power market. This paper presents a power market model that considers renewable portfolio standards (RPS), greenhouse gas (GHG) emissions cap-and-trade and green pricing programs. These are three concurrent policies in the United States that are expected to be implemented...
For a long time, China's coal-based energy structure, as well as thermal-power-led power structure, has caused serious environmental pollution problems. As the proportion of Chinapsilas power source structure is not so reasonable, it receives growing attention. To achieve the emissions constraints of major pollutants till the end of Eleventh Five-Year Plan, and optimize China's power structure, the...
The phenomenon of gradual warming of the planet has occurred for thousands of years, but it has been increasing in the course of the twentieth century due to the high concentrations of gases, which are responsible for the greenhouse effect. Recently, the scientific community has been debating and searching for new sources of renewable energies and the effects of the increasing emissions. Taking these...
This paper reports on results from an agent-based simulation model that comprises three interrelated markets in the electricity sector: a day-ahead electricity market, a market for balancing power, and a carbon exchange for CO2 emission allowances. Agents seek to optimize trading strategies over the two electricity markets through reinforcement learning; they also integrate market results from emissions...
This paper describes about the 20% Electricity from Wind scenario and it was examined not just for its feasibility but also for its benefits, costs and impacts on the energy sector, the economy, and environmental and climate change goals. This paper summarizes the principal results of these analyses, conducted primarily at the National Renewable Energy Laboratory (NREL) and the Lawrence Berkeley Laboratory...
