Global Energy Interconnection (GEI), a vision of a world power grid, was outlined by the State Grid Corporation of China («State Grid») It would be based upon a global network of Ultra High Voltage power lines connecting global power generation including massive wind farm at the North Pole and solar power from equatorial areas to energy users around the world.

«Each power conversion station is a combination of an inverter and a transformer that steps up the voltage roughly to 35 kilovolts, which goes to a PV combiner switch gear and then onto the substation and onto the grid connection.

The reality is that gas powered plants are still needed nearby to back up intermittent green power and to provide voltage (similar to water pressure) to push electrons through the electricity grid.

Additionally, batteries can not only allow renewable energy generation to become «dispatchable» — providing power on demand — but can also provide other grid support services including frequency regulation and reactive power for voltage stabilization.

Iron Horse, E.ON's first grid connected lithium battery system project, consisting of a 10 MW energy storage facility with an adjacent 2 MW solar array southeast of Tucson, Ariz., is online and helping Tucson Electric Power (TEP) maintain reliable electric service for more than 400,000 customers by providing frequency regulation and voltage control support.

The electricity generated is transformed into the higher voltages (up to 400,000 volts) used for economic, efficient transmission via power line grids.

For example, dynamic volt / var operations (also called dynamic reactive power compensation) of smart inverters allow systems to help counteract voltage deviations on the grid.

The power grid system in any country is a very closely controlled, finely tuned and highly sensitive network that must maintain the system voltage and frequency within very fine limits.

Small scale (less than about 4 MW) storage in electromechanical systems (rotating dynamic compensators) or statcomms (power electronics with batteries or capacitors) is used for grid stabilization (voltage and frequency) at the distribution level.

Today, the three main power grids — one for the eastern U.S., one for the West and one serving most of Texas — include more than 450,000 miles of high - voltage transmission lines.

The power grids in the U.S. — there are actually three of them — are enormously complex, but they're traditionally based on a simple idea: Electricity moves in one direction, from a power plant to homes along high voltage transmission lines and lower voltage power lines that distribute electricity to individual homes and neighborhoods.

Ultimately a plug on a hydrogen FCV could allow the vehicle to sell back hydrogen produced electricity for peak power needs or provide valuable voltage regulation services through the battery to further benefit the California electric grid.

The Plan involves building 23,000 km of high voltage transmission — both to connect the new power stations to the grid, and to connect the multiple existing grids to each other (so supply does not depend on the weather in one place).

Step - down transformers lower the voltage of electricity coming from the transmission grid, and distribution lines take the power to your home or business.

The nation could do this using only technologies available right now, and by introducing a national grid system connected by high voltage direct current (HVDC) that could get the power without loss to those places that needed it most, when they needed it.

Being supplied entirely by sun and wind entails various challenges in balancing the electricity grid and keeping the power quality with accurate voltage and frequency.
