What is power system economic operation?

From a general perspective, the power system economic operation involves the operation of generation, transmission, and distribution subsystems with the objective of operating these subsystems efficiently and fulfilling the requirement of maintaining the balance between generation and load at all times.

Why is economic operation important for a power system?

Economic operation is crucial for a power system to generate a profit on the invested capital. Maximizing efficiency minimizes the cost of electrical energy for consumers. Additionally, it helps reduce the rising prices for fuel, labor, supplies, and maintenance.
