Connectivity, however, is a common entry point, because so many clients have an immediate need to connect requesters to providers and want the benefits of the loose coupling the ESB provides.
D-STATCOM has been paid more and more attention since it can stabilize the voltage of the commoncouplingpoint and compensate the reactive power. But there are still many problems to be resolved.
