34 Glossary of Terms Islanded: not connected to a transmission grid. Microgrid: a small-scale power grid that can operate independently or in conjunction with the area's main electrical grid. Hybrid-Diesel: grid powered by diesel and other (renewable) power sources. Renewable Penetration: the fraction of renewable power (instantaneous penetration) or energy (average penetration) in the grid. Diesel-off: operation without (mechanical) synchronous generator. Grid-forming: inverter (DC-AC) system capable of regulating forming a grid from renewable energy sources or energy storage Organic Rankine Cycle (ORC) System: use of an organic fluid with a boiling point at a lower temperature than water to create work (energy) Asynchronous (Induction) Generator: electrical generator in which rotor and stator are not synchronized and requires external means to excite the rotor 35
