Generazione distribuita e vantaggi dei sistemi di accumulo

(presentazione in Inglese)

EC Energy Scenarios. The energy model includes a number of new features. Digitalization improves security, productivity, flexibility, sustainability and access of energy systems (i.e. SDGs) but introduces safety and privacy problems. Energy storage assets will contribute to the Energy Transition by allowing for the balancing of the net load generation supply

Lazard, 2018 Incentives mechanism Prosumers and energy communities Heating and cooling for buildings Sustainable mobility Bioenergy Governance EED, EPBD, RESD updating The energy model includes a number of new features 1. The establishment of Energy Union founded by 5 pillars: ' improved energy efficiency,
' a fully integrated energy market,
' decarbonization of economy,
' supply security of energy,
' research and innovation. 2. The role of flexibility of energy systems (supply flexibility) 3. The role of prosumer, the energy communities* 4. The Demand Side Management (demand flexibility) 5. Digitalization of energy, Web vs energy *End customers are explicitly entitled to become ''prosumers'', they can generate,
store and consume RE as well as sell
the excess production and participate in the
applicable support scheme, without losing their rights and obligations as end
customers connected to the grid and without being faced with discriminatory or
disproportionate procedures and charges
(Directive (EU)2018/2001 of EU Parliament) ' Transition is on the road
' Decarbonization targets lead toward 55-65% RES/electricity (2030)
' DG at 40% in 2030, with a substantial equilibrium between the roles of transmission and distribution networks. In Italy 750.000 GD plants
(2016), with a production of 63 TWh (22,2% of National production), ARERA
Delibera 222/2018/I/eel del 5 aprile 2018, PNIEC says to reach 40% (2030) ' Storages and production levelized at the same importance*
' Laws governing long term contract for RE
' RES included in the market of contracts
' Closed Distribution Systems CDS** as first operative example of Energy Communities * Del ARERA 300/2017/R/eel 5-5-2017, opening of MSD - Market of dispatching services of
the production '' to storage systems.
**A CDS is a network that distributes electricity within a geographically confined industrial,
commercial or shared services site. What do these new features mean' Digitalization of energy Digitalization improves security, productivity, flexibility, sustainability
and access of energy systems (i.e. SDGs)
but introduces safety and privacy problems
Digitalization modifies the traditional relationship between energy
demand/supply
DG and digitalization modifies energy and electricity market Digital technologies impact on the energy model because the
interconnection with:
' Smart demand response;
' RES (coherent) integration;
' Smart charging for Evs. Example: demand/response and RES flexibility; CDS; monitoring and
automation control of consumptions Innovation for EE, Smart Energy Systems ' Systems compatible with the evolution of the grid ' Smart Energy Systems, hybrid systems with high RES provision ' Large use of CHP, HP, 5th generation district heat/cooling ' Storages 11 Electrical, thermal, storage grids 12 ' RES feeding CHP (biomass, biogas, biomethane, hidrogen)
' RES in CHP to increase flexibility of supply systems
' Programmable biogas as RES target and balance systems avoiding investments ' 300 CHP with 1 MW capacity may modulate their production to get an energy of 1-2 TWh/anno ' RES presently leads a yearly balance need of 3-5 TWh/anno with a forecast destined to double within 2030 ' The need for legislation to allow CHP access to the dispatching market CHP and RES 1 Source: ENTSO '' E, Roland Berger Focus '' Business models for energy storage, 2017. 13 Battery storage
