The Research Of Apply Gas Turbines To Manege Wind Farm And Photovoltaic Power Variability

With the development of the society, has been a steady rise in demand for power at the same time, the traditional power production dependent on fossil energy is drying up, and the burning of fossil energy emissions of pollutants and carbon dioxide is the main cause of environmental pollution, climate warming.In the case of new energy power because of the abundant resources, widely distributed, clean pollution-free advantages received wide attention around the world, including wind power and photovoltaic power generation technology is relatively mature, have the advantage of scale development and utilization.But scenery power output has the characteristics of randomness, volatility, intermittent, large-scale parallel operation need other power supply output to adjust to changes in the landscape output adjustment.This paper aims at studying the characteristics of gas turbine regulating wind power, photovoltaic power.This paper statistics the scenery power installed capacity in recent years, growth situation and future development plan, to the given world wind/light wave power measures carried out extensive literature research, points out the necessity of flexible force power.Then compared the different flexible power output characteristics, configuration and operation situation at home and abroad, analyzes the current countries mainly adjust the way of scenery wave power supply, gas turbine regulation for a large number of literature research.To the specific characteristics of the gas turbine plant scenery in the peak shaving application running in a region data statistical analysis of the wind/light wave power output characteristics.Including typical scenario output characteristics, the monthly output analysis, hour efforts analysis and output wave characteristics.At the same time analyzed the four typical gas turbine manufacturer of simple cycle and combined cycle unit start-stop time, partial load efficiency, climbing unloading speed, pollutant emission levels, and minimum operation load regulation characteristics.Analyzes the characteristics of wind power, photovoltaic power and gas plants after adjustment ability, this paper designs the system of joint, to verify the gas turbine of wind power, photovoltaic power adjustment ability., according to the results of joint system in the operation of the gas turbine in strict constraints, even if the wind power, photovoltaic output volatility more severe cases, still can set goals for more than 99.5% of probability.Does not meet the points now starting up stopped, because to meet grade and the minimum output constraints, in the actual value does not accord with the theoretical value.Gas-fired power stations as adjusting the operation of the power supply, there will be a frequent start-stop and variable load operation condition, the efficiency of the unit, the maintenance cycle, the life cycle, the number of hours in use and so on have very big effect.Finally, the paper based on the analysis on the cost of the gas station, to adjust it as the power source runtime carries on the quantitative analysis of various factors affecting gas turbine efficiency.
