new UHVDC Analysis

Power stability analysis of UHVDC systems hierarchically ...2018-10-1The above limitation of the existing MC mode has led to tremendous challenges in the planning and design of new UHVDC projects. Under such circumstances, an innovative transmission pattern called the hierarchical connection (HC) mode [7] was proposed to connect a UHVDC link with the AC grid in two different voltage levels (i.e., 500 and 1000 kV).

    The inverter’s end of ultra high voltage DC (UHVDC) system under hierarchical connection mode (HCM) is connected to 500 and 1000 kV AC buses through high end converter and low end converter transformers, respectively. The two AC buses are interconnected via coupling transformer and the tie line. This complex structure of interconnection at inverter’s end can make the understanding unclear
