High voltage direct current is used in long-distance transmission. High voltage direct current power transmission systems use DC for electricity transmission. Owing to the DC, HVDC systems asynchronously connect power grids in that particular area which removes many outages- causing problems. HVDC transmission systems are cheap for long-distance electricity transmission & they also produce lower electrical losses. High voltage direct current systems allow transmission of power generated from solar panels & wind plants which are far away. The interconnection of High voltage direct current & the Alternative Current grid has strengthened the reliability & capacity of power grids. Rising electricity consumption is one of the main factors driving the global HVDC transmission market. The populace is rising rapidly, thereby growing the electricity consumption.
