Techno-economic and environmental analysis of community energy management for peak shaving

Energy storage (ES) is seen as the key to unlocking true potential of renewable generation it potentially supports their integration into grid by providing capability for services such balancing and frequency regulation. It also has reduce peak power demand reduction (a form arbitrage) this service will be important distribution companies frees capacity on grid. The first part study presents an energy management strategy (EMS) that reduces drawn from a community 60 homes using ES local (in case photovoltaic panels (PVs)). EMS tested hundreds cases shows average yearly around 30% in best cases. second paper tests economic viability greenhouse gases (GHG) emissions explored trade-offs exist between electricity supply costs, reduction, life cycle GHG reductions. PV provides significant but makes little contribution reducing In contrast, batteries) effective at demand, additional may result modest increase due associated with battery manufacture roundtrip efficiency. Future cost projections 2040 battery, together longer life, show considerable reductions can made encourage demand.
