Application Research Of The Wind Solar Hydrogen Consociation Type Independent Generates System

With development of human society and progress of civilized degree, the demand to energy by human is increasing swiftly and violently. Nowadays in the 21st century, the humanity develops the economy under the gradually strict restriction of limited resources and environmental protection requests, faced with great challenges by realizing the economical and social sustainable development. As the present energy structure being optimized, the developments and applications of new energy resource have been paid more and more attention by governments of all kinds of countries. Among all kinds of new energy resource, two kinds of the most potential energies are solar energy and wind energy.At home and abroad much investment is devoted to the wind power and solar photovoltaic and other renewable energy. The renewable energy application construction is developing rapidly. In this paper there is much research about the wind power and solar energy and other forms of power generation and grid, relatively less about the independent application of renewable energy generation system, least about how to use the independent application of renewable energy to solve the power shortage problems for the typical representative of Tibetan areas to the remote and isolated areas. At present many regions in China go short of power energy due to its geographical location, natural history and other factors, no electricity or lackage of electricity is conspicuous and the improvement of the people's living and development of economic will be restricted by the situations. However, there is abundant renewable energy for development and use in these areas. Application research about how to develop and use the renewable energy is the only way to solve shortage in the power in the remote area and also major and practical issues that deserve our explorations and studies all the time.In order to provide a reliable and stable power supply to the remote area, this paper describes the design of an independent wind/photovoltaic/hydrogen hybrid power system. Because wind energy and solar energy could produce a large amount of energy when natural resource is sufficient, how to effectively restore and use the energy in case of shortage of natural resource needs to be solved at present. The paper proposes the use of hydrogen energy and solves the influences to the quality and efficiency of the electricity generation system because of seasonal variations of renewable resources and better improves the utilization of renewable energy. To overcome the shortcomings of fuel battery's weak response to the short term and instantaneous peak power, this paper provides electricity to the load in such a way that there are super capacitor and super capacitor reactor auxiliary fuel cells parallel to the fuel cells in the terminal.The paper builds system models for wind/photovoltaic/hybrid power system by use of the simulation software MATLAB----Simulink.The paper gives a detailed analysis of the characteristics of the geography, environment and climate in the Tibetan Plateau, focuses on the application of wind power in this region and proposes corresponding plans. The configuration and its operation mode of the wind/solar/FC hybrid power generation system are put forward.Based on the transient response simulation to the wind/photovoltaic/fuel cell power system, it proves that FC/UC system can be used in the wind/photovoltaic generating system to overcome the adverse effects brought by the random changes of the wind and solar power. The system could provide a good quality of power supply even if wind speed and user's load change. Meanwhile strong power supply reliability of the hybrid power system has been demonstrated, and the system could be used in the remote areas of Tibet where there are many changes in the light and wind.This paper attempts to solve the electricity needs of the people in remote areas where there is no power and a special area for representatives of the Tibetan plateau, does some application researches about energy power generation system consisting of wind, light and other forms renewable energy with specific purpose and application and a strong theoretical and practical significance.
