“…The configurations have diversified over time with the inclusion of various hybrid DGS systems such as PV-hydrogen, PV-diesel-battery [27], PV-wind-battery [28], PV-wind-diesel [29], PV-wind-diesel-battery [30], and PV-wind-diesel-hydrogen-battery [31]. The list of configurations could be much longer if other generation types (e.g., bioenergy, hydro, gas turbine) and storage (e.g., hydro, compressed air, flywheel, capacitance, chemical conversions)…”
