Research On Abandoned Wind Mobile Thermal Storage Heating

With the continuous progress of the power industry,new energy power generation technology is becoming more and more mature,especially wind power generation technology is not only low cost but also environmental protection has been widely used in the world.China's vigorous development of wind power technology has not only accelerated the energy transition,but also importantly fulfilled the goal of preventing and controlling air pollution.With the continuous expansion of China's wind power installed capacity and continuous innovation in power generation technology,China's offshore wind power and onshore wind power have developed rapidly,and wind power has become an important alternative energy source.At the same time that the wind power industry has achieved remarkable results,the problem that wind power cannot be completely absorbed is also increasingly prominent.China's wind power generation is facing difficulties in long-distance output and local consumption.Mainly due to the mismatch between wind energy resources and local demand,the adaptability of the power grid cannot meet the needs of accepting all wind power,it is difficult to absorb wind power,and the problem of increasing wind power generation year by year is also highlighted.At present,the problem of curtailing wind curtailment has seriously hampered the sustainable and healthy development of China's wind power industry.Under the condition that the installed capacity of wind power is increasing,the situation of wind curtailment becomes more and more serious.In order to promote the energy transition,effective measures must be taken to solve the problem of wind abandonment.In view of the current situation of insufficient power transmission capacity in the Inner Mongolia Autonomous Region,a large amount of power cannot be output,it is proposed to use the solid heat storage technology of the German company SCHüRER-BENZ to design a mobile energy storage heating device that can use trough wind power,including electric heating devices,solid heatstorage Body,heat exchanger,frequency converter and other technologies.Design a supporting intelligent control system that uses electricity from wind farms during periods of abandonment of wind power as energy,converts it through mobile energy storage heating devices,and outputs steam or high-temperature water with mobile heat energy to convert electrical energy into heat energy.The matching intelligent control system realizes the automatic operation of the system.Design specific operation schemes for mobile energy storage heating.Finally,the economic benefit analysis of the project is calculated.Converting the electricity during the wind abandonment period into heat energy is stored in a solid medium and can be transported to a nearby thermal industrial park or residential area at any time,which not only solves the problems of waste of wind energy resources of wind farms and the limitation of wind power during heating.At the same time,it also solves the problem of air pollution caused by the heating of traditional coal-fired boilers.The use of wind power to abandon wind power for energy storage and heating energy is highly efficient,energysaving,and economical in operation.It can effectively alleviate wind abandonment,improve wind energy utilization efficiency,and achieve electrical energy substitution.It has good social and economic benefits.
