연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A wind energy generating and storage system, comprising:a plurality of ground based windmill stations located in a predetermined area, wherein said plurality of windmill stations is divided into at least two kinds; a predetermined number of first windmill stations having a first wind turbine and an electrical generator adapted and exclusively dedicated to converting wind energy into electrical energy for immediate use; and a predetermined number of second windmill stations having a second wind turbine adapted and exclusively dedicated to storing energy produced by the wind in at least one storage tank, wherein at least one compressor is provided to compress air into said tank, at least one expander is provided to release the compressed air from said tank, and a second generator is provided to convert compressed air energy into electrical energy. 2. The system of claim 1, wherein at least one heating device is provided to heat the compressed air that is released and expanded.3. The system of claim 2, wherein said at least one heating device is taken from the group consisting of the following:a. a device which derives heat from solar energy; b. a device or mass which derives heat from said at least one compressor; c. a heating device which uses its own energy source; d. a heat exchanger having tubes extending through said tank, wherein a heated fluid can be passed through said tubes to increase the temperature of the air inside said tank. 4. The system of claim 1, wherein the predetermined number of said first windmill stations and the predetermined number of said second windmill stations are based on the wind characteristics of the area where the stations are located and the use characteristics of the area where the energy from the system is used.5. The system of claim 1, wherein a refrigerating device is operatively connected to said system to enable the cold temperatures generated by said compressed air being released and expanded to be used for refrigeration purposes.6. The system of claim 1, further comprising a predetermined number of hybrid stations which can be simultaneously switched between providing energy for immediate use and providing energy for storage.7. The system of claim 6, wherein said hybrid stations each comprise a wind turbine for generating mechanical power, a splitter for splitting the mechanical power generated by said hybrid stations, wherein said splitter is capable of simultaneously apportioning and adjusting the amount of mechanical power between a first converter for generating electricity for immediate use, and a second converter for generating compressed air energy into at least one tank.8. A method of generating and storing energy, comprising:providing a predetermined number of first windmill stations, each having a wind turbine and an electrical generator adapted and dedicated to converting wind energy into electrical energy for immediate use; providing a predetermined number of second windmill stations having a second wind turbine adapted and dedicated to storing energy produced by the wind in at least one storage tank, wherein at least one compressor is provided to compress air into said tank, at least one expander is provided to release the compressed air from said tank, and at least a second generator is provided to convert compressed air energy into electrical energy; and providing a predetermined number of hybrid windmill stations having a third wind turbine adapted and dedicated to converting wind energy into electrical energy for immediate use, and/or storing energy produced by the wind, wherein said hybrid windmill stations can be switched between providing energy for immediate use and providing energy for storage. 9. The method of claim 8, wherein the predetermined numbers of said first, second and hybrid windmill stations are determined based upon the wind histories of the area where the stations are to be located, and the demand characteristics of the area where the energy from the stations are to be used.10. The method of claim 9, wherein other design considerations are taken into account, including the size of said at least one tank, the capacity of the compressor, the capacity of the expander, the total number of windmill stations to be installed, the availability of an auxiliary burner as a back-up energy supply, and the availability of one or more heating devices to heat the compressed air to be released and expanded.11. The method of claim 8, wherein the predetermined numbers of said first, second and hybrid windmill stations are determined based on a ratio of about 65 percent immediate use windmill stations and 35 percent energy storage windmill stations.12. The method of claim 8, wherein the design takes into account daily wind and energy demand histories for a given location, which are obtained for predetermined periods of the year.13. The method of claim 12, wherein an estimate is made, based on the daily histories, of the total number of said first and second windmill stations to install, based on the worst mismatched predetermined periods.14. The method of claim 13, wherein an iterative process is used to determine a system which can provide energy to said given location on an uninterrupted and continuous basis, in a cost-effective and energy-efficient way.15. The method of claim 12, wherein the predetermined periods of the year are seasons.16. A wind farm for generating and storing energy, comprising:a plurality of windmill stations located in a predetermined area, wherein said plurality of windmill stations is divided into at least three types; a predetermined number of first windmill stations having a first wind turbine and an electrical generator adapted and dedicated to converting wind energy into electrical energy for immediate use; a predetermined number of second windmill stations having a second wind turbine adapted and dedicated to storing energy produced by the wind in at least one storage tank, wherein said at least one storage tank has associated therewith at least one compressor to compress air into said at least one tank, at least one expander to release the compressed air from said at least one tank, and a second generator to convert compressed air energy into electrical energy; and a predetermined number of hybrid windmill stations having a third wind turbine adapted and dedicated to converting wind energy into electrical energy for immediate use, and/or storing energy produced by the wind, wherein said hybrid windmill stations each comprise a splitter for splitting mechanical power generated by said third wind turbine, wherein said splitter is capable of simultaneously apportioning and adjusting the amount of mechanical power generated by said third wind turbine between a first converter for generating electricity for immediate use, and a second converter for generating and storing compressed air energy in at least one storage tank. 17.
