Research On The Application Of Superconducting Magnetic Energy Storage In The Enterprise Power Grid

With the expansion of industrial scale and the development of science technology, theautomation of the commercial unit gets higher and higher which made the companies askhigher requirers to the quility of electric energy. New equipment and technologies to raise thequility of electric energy are used in companies in practise, but there’s still some problems tosolve based on the application situation.Many large companies like Sinopec are facing big problem-Shacking Electricity. Thiscontinuing problem will have a different influence on the companies. At present it can only besolved by traditional methods like shunt capacitor, however, as the growing of companies’loading capacity and the rising of equipment measure of precision, it cannot fulfil therequirements of the larger companies any more.To find a better solution of the Shaking Electricity problem, based on present methods,this paper raised the idea that the Shaking Electricity problem can be solved bysuperconducting energy storage. The main ideas are as follow:Firstly, it generally described the present situation of Shaking Electricity problem and theprospect of superconducting technology in electric system, and put forward the importance ofusing SMES to solve the Shaking Electricity problem. It also analysis the reactive powerplanning of electric system and its existent problems.Secondly, it introduced the Continuous Power Flow Method and Ant ColonyOptimization, which provides the theoretical foundation of the application of SMESinstallation site and capacity selection.Thirdly, it analysis the mathematical model of SMES and it worked out the bestinstallation site using the Continuous Power Flow Method. It also simulates ShakingElectricity in SINOPEC decompression station, connected with SMES, analysis transientvoltage and verified the optimality of the best installation.At last, it used Ant Colony Optimizationto find out the best installation capacity of theinstallation site chosen before.This paper finds out other capacities and sites, based on SMES, and provide theoreticalfoundation of it for further practise. With the development of high temperture superconductortechnology and power electronics technology, SMES can be widely used in the future.
