Conclusion

In this study, the impact of wind power generation on peak-time power supply and on overall power mix is examined considering the intrinsic uncertainty of wind power. As a result, the impact of wind power on peak time supply on 2030 is turned out to be a non-negligible level of up to 4.41 . For additional investment cost, a minimum of 31.5 million dollars and a maximum of 28 billion dollars of additional investment are estimated to be required in terms of LNG 700 MW facilities. The result is...

Analyzing Peak Time Impact of Wind Power

For the convenience of our analysis, both the power curve of a wind turbine and wind speed at the national level is simulated with certain constraints. Wind speed data for the areas of Youngdeok, Jeju-hanrim, Saemangeum, Seosan, and Samcheok from Sep. 12, 2000 to Sep. 11, 2000 from the wind map of KIER (Korea Institute of Energy Research) is selected for such purposes. For practical simulation, 365 x 5 random numbers are created first to select 365 days' wind speed patterns for 24-h intervals....

Wind Power Generations Impact on Peak Time Demand and on Future Power

Abstract Although wind power is regarded as one of the ways to actively respond to climate change, the stability of the whole power system could be a serious problem in the future due to wind power's uncertainties. These uncertainties include intermittency and the fact that wind power cannot be relied upon to supply energy on demand, including and especially during periods of peak demand. From this perspective, the peak-time impact of stochastic wind power generation is estimated using a...

Opportunities of Renewable Energy and Distributed Generation

In February 2006, the government of Indonesia enacted Presidential Decree No. 5 2006 for National Energy Policy. In this policy, the share of new and renewable energies in energy mix will be increased from around 5 in 2007 to more than 17 in 2025, which are composed of bio-fuel (5 ), geothermal (5 ), coal liquefaction (2 ), and others, including nuclear (5 ). Supporting the policy, abundant resources are already available in Indonesia. Table 1 summarizes the national energy potency of...

Opportunities and Challenges of Renewable Energy and Distributed Generation Promotion for Rural Electrification in

Abstract This paper reviews the opportunities Distributed Generation (DG) has to solve electrification problems in Indonesia, especially for rural areas. The main approach used in this paper is comparison, with a focus on other countries who share similar conditions. Renewable energy sources are examined from the perspective of sustainability and environmental friendliness. For rural areas, geographical disadvantages serve to increase the competitiveness of renewable energy and DG. An abundant...

The Challenge of Sustainable Energy Supply

Energy demand and energy supply gap Vietnam is a net exporter of energy with 15 million tons of crude oil and 31 million tons of coal exported in 2007. In fact, the country has imported oil products because the first refinery plant has just begun operations this year. Recently, due to a shortage of electricity, Vietnam had to import power from China amounting to 550 MW in 2007. Moreover, Vietnam has also imported about 200,000 tons of fat coal per year for industry production for the last three...

Introduction

Energy security can be defined as the adequacy, reliability and affordability of energy supply to support the functioning of the economy and social development. In other worlds, energy security is the provision of sufficient energy to support economic and social activity with minimal disruption and at reasonable prices. Vietnam, a country that has emerged as one of the most active economies in the world in recent economic history, is also facing a visible set of challenges relating to energy...

First of all, the dissolved state of silicon chloride species in TMHATFSA was investigated by Raman spectroscopy. Figure 1 summarizes the results of peak separation for the vx symmetric stretch mode of SiCl4. It exhibits almost no influence of TMHATFSA on the peak position and width for the vx mode of SiCl4 in the electrolyte solutions. It means that silicon chloride species exists mainly as SiCl4 molecules in TMHATFSA without making bonds with other molecules to form complexes, polymers, or...
