Motivation• Looking beyond 2030, the challenges for electricity

networks are likely to increase.

• There exists general consensus that the challenges of

climate change, economic development and system

security.

• The ability to accommodate significant volumes of

decentralised and renewable generation, require that the

network infrastructure must be upgraded to enable

smart operation.

The other half of the challenge lies

in building the transport and

distribution networks

As the low-emission economy

evolves, building new generation

technologies is just half the

challenge

Motivation• The future electricity networks and its potential issues

require looking beyond the existing research frontiers

irrespective of the disciplinary boundaries.

• For this reason, the discussion of the future development on

sophisticated/intelligent applications/solutions is the key

research point to provide the critical importance to economic

and social welfare into future smarter networks.

Objective and ScopeObjective:

• The objective of this seminar is to present the fundamental

aspects about system frequency control and inertia

response schemes for the future electrical systems.

High Voltage DC (HVDC)

Wind Power Integration

Scope:

• This seminar is developed not to be intended a generic case

of all possible future scenarios and technologies, instead of

that this seminar is focuses on the expected development

to UK system.
