2. Stand-alone power system - Wikipedia

   en.wikipedia.org/wiki/Stand-alone_power_system

   A typical stand-alone solar PV system at a sewage treatment plant in Santuari de Lluc, Spain. Stand-alone photovoltaic power systems are independent of the utility grid and may use solar panels only or may be used in conjunction with a diesel generator, a wind turbine or batteries. [1] [2]

3. Induction generator - Wikipedia

   en.wikipedia.org/wiki/Induction_generator

   In induction generators, the reactive power required to establish the air gap magnetic flux is provided by a capacitor bank connected to the machine in case of stand-alone system and in case of grid connection it draws reactive power from the grid to maintain its air gap flux. For a grid-connected system, frequency and voltage at the machine ...

4. Standby generator - Wikipedia

   en.wikipedia.org/wiki/Standby_generator

   Standby generators. A standby generator is a back-up electrical system that operates automatically. [1] Within seconds of a utility outage an automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load to the generator. The standby generator begins supplying power to the circuits. [2]

5. Hybrid power - Wikipedia

   en.wikipedia.org/wiki/Hybrid_power

   Hybrid renewable energy systems are becoming popular as stand-alone power systems for providing electricity in remote areas due to advances in renewable energy technologies and subsequent rise in prices of petroleum products. A hybrid energy system, or hybrid power, usually consists of two or more renewable energy sources used together to ...

6. Solar power - Wikipedia

   en.wikipedia.org/wiki/Solar_power

   The overwhelming majority of electricity produced worldwide is used immediately because traditional generators can adapt to demand and storage is usually more expensive. Both solar power and wind power are sources of variable renewable power , meaning that all available output must be used locally, carried on transmission lines to be used ...
