Query: Dynamic control of intermittent renewable energy fluctuations in
  two-layer power grids   In this work we model the dynamics of power grids in terms of a two-layer
network, and use the Italian high voltage power grid as a proof-of-principle
example. The first layer in our model represents the power grid consisting of
generators and consumers, while the second layer represents a dynamic
communication network that serves as a controller of the first layer. The
dynamics of the power grid is modelled by the Kuramoto model with inertia,
while the communication layer provides a control signal P_i^c for each
generator to improve frequency synchronization within the power grid. We
propose different realizations of the communication layer topology and of the
control signal, and test the control performances in presence of generators
with stochastic power output. When using a control topology that allows all
generators to exchange information, we find that a control scheme aimed to
minimize the frequency difference between adjacent nodes operates very
efficiently even against the worst scenarios with the strongest perturbations.
On the other hand, for a control topology where the generators possess the same
communication links as in the power grid layer, a control scheme aimed at
restoring the synchronization frequency in the neighborhood of the controlled
node turns out to be more efficient.
