A wide area synchronous grid (also called an "interconnection" in North America) is a three-phase electric power grid that has regional scale or greater that operates at a synchronized utility frequency and is electrically tied together during normal system conditions.
The electric power transmission grid of the contiguous United States consists of 120,000 miles (190,000 km) of lines operated by 500 companies. The electrical power grid that powers Northern America is not a single grid, but is instead divided into multiple wide area synchronous grids. [1]

The electric power transmission grid of the contiguous United States consists of 120,000 miles (190,000 km) of lines operated by 500 companies. The Western Interconnection is a wide area synchronous grid and one of the two major alternating current (AC) power grids in the North American power transmission grid .
A microgrid is a local grid that is usually part of the regional wide-area synchronous grid but which can disconnect and operate autonomously. [5] It might do this in times when the main grid is affected by outages. This is known as islanding, and it might run indefinitely on its own resources.
A wide area synchronous grid, known as an interconnection in North America, directly connects generators delivering AC power with the same relative frequency to many consumers. North America has four major interconnections: Western, Eastern, Quebec and Texas. One grid connects most of continental Europe.

Power engineering software is a software used to create models, analyze or calculate the design of Power stations , Overhead power lines , Transmission towers , Electrical grids , Grounding and Lightning [ clarification needed ] systems and others.
The area under the dispatch curve to the left of this line represents the cost per hour of operation (ignoring the startup costs, $30 * 120 + $60 * 30 = $5,400 per hour), the incremental cost of the next MWh of electricity ($60 in the example, represented by a horizontal line on the graph) is called system lambda (thus another name for the ...
