Economic and environmental impact of photovoltaic and wind energy high penetration towards the achievement of the Italian 20-20-20 targets

摘要: The paper presents an analysis of the operating parameters Combined Cycle Gas Turbine (CCGT) systems in Italy years from 2006 to 2013, studying environmental and economic impact renewable energy sources spread on CCGT. Variable Renewable Energy (VRE) development, electricity demand reduction CCGT overcapacity have affected that had operate at partial load, experiencing several rump-up/down cycles a day. consequent increase CO 2 emission costs be considered RES high penetration future scenario. aims evaluate net avoided emissions by cost incurred avoid emit tonne . To reach targets attention is switching problem adding more installations managing whole “green” production smarter way. Considering all indirect effects caused system essential for everyone who wants analyse scenarios.
