| خلاصه≠ | Economic Dispatch (ED) is the process of optimally allocating power output among committed generators to meet demand at minimum fuel cost. Introduced by Kirchmayer in 1958, ED is a fundamental real-time optimization problem solved every few minutes in power system operations. Unlike Unit Commitment (which decides generator on/off), ED assumes generators are already committed and focuses on splitting load most economically. ED's rapid feedback enables efficient real-time power plant operations. | Power System State Estimation (PSSE) is a real-time algorithm that estimates the voltage and phase angle at every bus in a power grid from a set of noisy, redundant measurements. Introduced by Schweppe in 1970, it combines measurements (power flows, voltage magnitudes) with the physical power flow model to produce the most likely system state. State estimation is the foundation of modern grid control centers, providing operators with an accurate digital representation of the actual network. |
