modeling and optimization in vsc-hvdc transmission lines in chemical industry, a review

Abstract high voltage direct current system is a type of high voltage direct current transmission system. this method is a new way to transfer electrical energy on a large scale and so it is a good alternative to traditional method (using alternating current). an integrated system is required to transfer electricity from power plants to consumers. this system includes energy production centers, stations, transmission lines or cables and egyptians. in this article, we will evaluate the vschvdc transmission system and line stability methods will be evaluated in the presence of scattered production resources. for this reason, in the first part, the hvdc system, the twolevel vsc control converter will be expressed and in the second part, a summary of scattered production sources (wind turbine and photovoltaic system) will be expressed.
