  The ATLAS model simulates the various stages of the electricity market chain
in Europe, including the formulation of offers by different market actors, the
coupling of European markets, strategic optimization of production portfolios
and, finally, real-time system balancing processes. ATLAS was designed to
simulate the various electricity markets and processes that occur from the day
ahead timeframe to real-time with a high level of detail. Its main aim is to
capture impacts from imperfect actor coordination, evolving forecast errors and
a high-level of technical constraints -- both regarding different production
units and the different market constraints. This working paper describes the
simulated balancing processes in detail and is the second part of the ATLAS
documentation.
