in system planning are greater than in any of the previous categories that I
have mentioned. This area of
concern is currently based on different disciplines that have different
concerns. An integrated approach
to system planning is sorely lacking.
should be possible to integrate the open circuit models currently being used
by earthquake engineers with the dynamic load/generation balancing models
used by electrical engineers for system planning. Many of these models cover quite large
areas. An integrated model would
be able to predict earthquake disruption of electric power flow and possible
times of restoration of service outside the earthquake area.
models have been developed to describe the impact of electric power
disruption on economic sectors within a region. These models need to be enhanced into
tools that can be related to customer types in an electric utility’s
but not least is the memory of how our power grids have experienced cascading
failures. Recent experience of
how difficult and time consuming it is to restore power using operators and
centrally located control centers underscores the potential problem, when an
earthquake occurs that destroys a significantly larger number of electric
power facilities. The technology
of SCADA systems is advancing in a fashion similar to the decentralized
computer network control systems.
If research can keep pace with technology, self healing power systems
in areas that have undamaged facilities, could be broadly available over the
next ten years.
