Query: Green power grids: how energy from renewable sources affects network and
  markets   The increasing attention to environmental issues is forcing the
implementation of novel energy models based on renewable sources, fundamentally
changing the configuration of energy management and introducing new
criticalities that are only partly understood. In particular, renewable
energies introduce fluctuations causing an increased request of conventional
energy sources oriented to balance energy requests on short notices. In order
to develop an effective usage of low-carbon sources, such fluctuations must be
understood and tamed. In this paper we present a microscopic model for the
description and the forecast of short time fluctuations related to renewable
sources and to their effects on the electricity market. To account for the
inter-dependencies among the energy market and the physical power dispatch
network, we use a statistical mechanics approach to sample stochastic
perturbations on the power system and an agent based approach for the
prediction of the market players behavior. Our model is a data-driven; it
builds on one day ahead real market transactions to train agents behaviour and
allows to infer the market share of different energy sources. We benchmark our
approach on the Italian market finding a good accordance with real data.
