Description
Modern power grids are currently affected by major changes in
terms of technology, resiliency and efficiency, among others, as
exemplified by the use of renewable energy sources and smart
technology. Modelling and optimisation of large energy grids will
be complicated by the changes mentioned above. To address and
achieve the future goals of grid operation the project develops
further analysis of power grids by a two-stage modelling and
simulation process.
The focus is on mesoscopic power grids and their stochastic
modelling. On the one hand, these are still closely related to
power production and consumption, and on the other hand, they are
not far away from the modelling of global grids. The modelling
approach covers two specific and innovative modelling and
assessment levels. The first approach is a quantitative
resilience assessment and results in Resilience Priority
Values (RePV). To compute the network RePVs we plan to work on two
major problem areas: (1) provision of a tailored resilience metric,
and (2) simplified approach for grid resilience audits.
On the second level we expand the basic entities (buses) with
stochastic power flow modelling based on the bottom-up architecture
and performance of real power grids using a description of
individual power consumers and producers. In the next step we use
the specific (near to scale-free) network architecture, DC
approximation and fast linear solver to provide a rapid optimal
power flow prototyping which can be used to refine grid stability
(resiliency) and to analyse the impact of any system
optimisation measures in the grid architecture.
Hence, these modelling steps lead from a simple overview model to
an advanced stochastic power flow model on the mesoscopic
level. The results can be industrially used by grid providers,
energy suppliers and regulatory institutions in determining the
resilience levels and in optimising the design, evaluation
and optimisation of modern grids.
