Improving the Global energy Industry by Integrating Macro-Technologies:Challenges and Opportunities for Corporations

energy and Power Engineering 2013年第10期5卷 604-621页

作者： Jose M.“Chema”Martínez-Val Piera ETSI Minas Universidad Politecnica de MadridMadridSpain

Emerging energy technologies and market evolution of some energy products, particularly natural gas, can converge to produce a new global scenario closer to the objectives of Sustainable Development, with a smooth transition that would avoid social and economic upheavals and could open a new cycle of growth and wealth. The first steps of unconventional gas production have induced stabilization in the gas spot price that should be continued to guarantee stable prices in the long term. Another line of development that should start a second phase of consolidation and cost reduction is the field of Renewable Energies. Besides research and technology advancements, a new financial deal could substitute for subsidies and feed-in tariffs. Last but not least, electric vehicles and other emerging technologies from the demand side will also have a main role in this quest to re-structure the energy sector, where a new hierarchy of energy goods and energy applications will appear, and a better integral use of energy will take place. A main consequence of that will be a significant reduction of CO2 emissions, and a cheaper cost of energy, although fiscal policies could swallow this advantage. In this transition, which would likely last thirty years or so, energy corporations will have to face challenges and opportunities to consolidate their working and value-adding status.

This paper presents a method for optimal sizing of a Micro grid connected to a hybrid source to ensure the continuity and quality of energy in a locality with a stochastically changing population. The hybrid system is composed of a solar photovoltaic system, a wind turbine, and an energy storage system. The reliability of the system is evaluated based on the voltage level regulation on IEEE 33-bus and IEEE 69-bus standards. Power factor correction is performed, despite some reliability and robustness constraints. This work focuses on energy management in a hybrid system considering climatic disturbances on the one hand, and on the other hand, this work evaluates the energy quality and the cost of energy. A combination of genetic algorithms of particle swarm optimization (CGAPSO) shows high convergence speed, which illustrates the robustness of the proposed system. The study of this system shows its feasibility and compliance with standards. The results obtained show a significant reduction in the total cost of production of this proposed system.

This paper introduces a computer program to choose the most suitable wind turbine for each site according to technical and economical *** criterion for choosing the most suitable wind turbine for each site is according to which wind turbine and site give a maximum capacity factor and minimum cost of energy（$/kWh）.This criterion is used because the decision of matching which depends only on maximum capacity factor is not enough because capacity factor is independent of rated power of wind ***,two wind turbines with the same performance parameters but different rated power get the same capacity factor for the same site but it does not get the same cost of energy（$/kWh）.The computer program has been applied on five locations in Saudi *** five locations are Yanbou,Dhahran,Douhlom,Riyadh and *** wind turbine parameters such as hub height,rated power,cut-in,rated,and furling wind speeds for ten commercial wind turbines are *** Weibull parameters have been estimated numerically and graphically for these five *** values of Weibull parameters obtained graphically are similar to the numerical *** methods have been used for estimating the cost of *** results from these three methods have been compared and the suitable one for Saudi Arabia economics has been selected.
