The Manitoba Hydro major transmission system features a topology consisting of very high HVdc penetration level, tightly coupled rectifiers as well as tightly coupled inverters. The tight coupling at the rectifiers or the sending end results in multi-egress system characteristics, where as the tight coupling at the inverters or the receiving end results in its multi-infeed characteristics.

National Grid in its capacity as both a Transmission Owner and System Operator is experiencing changes in the network characteristics, brought about by changing patterns in generation, transmission and demand technology. This paper discusses some observations around network performance and shares some thinking on the opportunities and considerations for new technology solutions to contribute to a...
This paper considers two reactive power compensation devices for HVDC converter stations, the synchronous condenser (SC) and the Static Synchronous Compensator (STATCOM). The contribution of these devices to the networks inertia is very different. The paper discusses the impact of this inertia on frequency stability in the ac network. The impact is analyzed using analytical studies as well as numerical...
