I think your problem is two incompatible AVR for fast and suitable VAR sharing, specially in transient conditions. As mentioned above, respond time of digital and analog control systems is not same and you should advise with manufacturer for the best modification of whole control systems. In fact delay response of one AVR (digital type) cause the transfer delay of loads from one genset to another which can cause mentioned VAR sharing limitation.
