Current NETS SQSS network operation and planning standards do not take into
consideration reserve requirements when determining network capacity. A rapid
growth in wind generation in the future will significantly increase the requirement
for various forms of reserve and explicit consideration of the impact on network
constraints on the allocation of spinning and standing reserves across the
system may become important. Similarly, increased reserve requirements may
impact on the need for transmission capacity. It is expected that under some
circumstances, it may be appropriate to reinforce the transmission network in
order to access cost effective resources of reserve that may be in the form of
generation or demand.
If this work shows that there are significant benefits from incorporating reserve
requirements in network planning, this could be used to consider changing
network design standards to include reserve requirements in addition to
considering peak demand conditions and constraint costs. It is proposed to carry out this analysis on predicted generation and demand background for the year
2020 and investigate whether the inclusion of generation and demand reserve in
planning methodology would deliver economics benefits.
Imperial College will undertake a research project, under the supervision of Prof.
Goran Strbac to establish this understanding and to propose alternative
methodologies that might be practical to be applied to a real power system.
This project will deliver an assessment of the effects of including both generation
and demand side reserve in real time operation and transmission capacity
planning in systems with significant penetration of wind generation. The twin
objectives are to:
- Assess how network constraints impact on allocation of spinning and standing
- Investigate whether investment in new transmission capacity may provide more efficient access to reserves needed to support cost effective integration of wind
generation. This work should provide information that will be used to assess if
the network planning approach should change to incorporate reserve
requirements in National Grid systems with wind generation.
The research will:
- Assess the importance of an approach to reserve management that
dynamically optimises the allocation of spinning and standing reserves in the
presence of transmission constraints
- Develop a methodology for quantifying the impact that generation and
demand side reserve has on the transmission capacity requirements
- Against current National Grid generation and transmission reinforcement predictions
for the year 2020 identify where and how much additional transmission capacity
would be justified to allow generation and demand side reserve to be effectively
utilised in order to reduce operational cost and support wind integration. The
opportunities for generation and demand side reserve will be characterised
against the predicted demand and generation background for 2020.
