Progetto MERCATI ELETTRICI: Evoluzione dei sistemi elettrici interconnessi e integrazione dei mercati. Rapporto di sintesi dell'attività 2015


In the last decade the new policies of European Community and of the Member States are shaping concrete modifications in the national power market and system. Under the impetus of the technical, economical, environmental and social drivers, the power system assumed a new layout which is characterised by an arising integration in the grid of non-dispatchable renewable production and by a greater proportion of distributed generation instead of bulk generation.

The transformation is ongoing also in the European power exchanges and it has the target of an Internal Electricity Market (IEM): currently, concerning the Day-ahead market coupling, this process is quite advanced, for the next years an expansion is expected to the intra-day market and to the balancing market.

In the research project “Evolution of interconnected electrical systems and market integration” activities have been oriented towards the power market analysis, focusing both on the current drawbacks and on the long term evolution of the system, of its management and of its regulatory framework.

In this context RSE collaborated with the Authority of Energy (AEEGSI) in the RDE Project (Dispatching Reform) aiming at the reorganization of the balancing market.

In particular a theoretical analysis of three different possible models for the balancing market has been performed.

Furthermore, a competitiveness analysis has been performed about the combined-cycle gas-turbines in the current state of the power market and a scenario of the balancing market demand at 2030 has been carried out.

In the european project “eBADGE” some analyses of a possible market integration amongst Italy, Austria and Slovenia has been realized by way of a cross-border balancing market simulator developed on purpose.

Some of the activities have been oriented towards the development of software tools, for instance a simulator of Italian Ex-Ante Ancillary Services Market (ASM) and a tool to evaluate the minimum necessary amount of Operating Reserve (Active Power Tertiary Reserve) in presence of more ASM sessions with respect to the present ones.

Finally, considering the possible evolution of the Electricity Market Rules, we present some evaluations of the contribution to the primary frequency regulation by thermostatic loads, taking into account the availability of these resources. Finally, a primary frequency control logic has been proposed for wind generators.
