What does the term 'Dispatch' refer to in the context of grid operations?

In the context of grid operations, the term 'Dispatch' refers to the apportioning of the total demand of the grid. This process involves determining which power generation units to activate and how much power each unit should generate to meet the current demand while ensuring stability and reliability in the power system.

Dispatch considers various factors, including the availability of generation resources, fuel types, operational costs, and system constraints. By effectively managing the dispatch of power, grid operators can maintain a balance between supply and demand, minimizing the risk of blackouts and optimizing the overall efficiency of the power system.

In contrast, other options do not align with the core definition of dispatch within grid operations. The process of repairing electrical circuits relates to maintenance rather than real-time demand management. The expansion of power generation stations is more about infrastructure development, and the installation of new electrical infrastructure pertains to physical upgrades rather than the operational aspect involved in addressing demand. These aspects are important in their own right, but they do not capture the essence of 'Dispatch' as used in grid operations.
