    I have attached the picture of VSC-based HVDC link system. Refer to figure_1, it consists of two converters. When I demand active power from one converter, the other converter follows this demand of active power. On the other hand, when I demand the reactive power from one converter, the other converter DOES NOT follows this demand of reactive power. (For reactive power, there is only one converter response to the demand value.) Can anyone explain this to me why both converters do not response in the same way for the demand of active and reactive power?

    It's a question of what it's designed for. Most assume a real load and are unprepared to handle a reactive load. t's really in the design of the inverrter. Can you tune out the reacttance to make it real?

    What do you mean by tuning out the reactance to make it real?
    I meant that either of the converter is capable of producing the reactive power accordingly to its demand(Iq) but it won't effect another one. Why it won't effect each other?
