Working Group: RE-Hybrid Systems on Islands General Explanation � What is Hybridization? What to How to hybridize: Hybrid system hybridize: • Photovoltaics (PV) types: • Wind • Diesel • Hydropower • Gas • Stand-alone (islands) • Storage (various • Heavy fuel oil • Mini-grid Battery technologies, • Waste-to-energy • Micro-grid Hydrogen) • Biomass-to-energy

Working Group: RE-Hybrid Systems on Islands Simulation and Optimization � ENERGETIC RESULTS - Grid stability considerations (without battery) • Reliable Energy Management System to ensure grid stability is key VARIABILITY CONSTRAINT 1 : PV 50.00 VARIABILITY CONSTRAINT 2 : LOAD Cloud event reducing PV power output Starting power from a large scale motor 45.00 (worse case: up to 50-70% in <10sec) (up to 3 times the nominal power of motor) Failure of a PV inverter 40.00 35.00 Power (MW) 30.00 25.00 Power supplied 20.00 VARIABILITY CONSTRAINT 3 : DIESEL by Diesel engines Failure of a running Diesel Generator 15.00 10.00 Power supplied 5.00 by PV plant 0.00 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
