Muhtasari	Unit Commitment (UC) is the problem of deciding which power generation units should be switched on or off over a planning horizon (typically 24-168 hours) to minimize total operating cost while meeting demand and reserve requirements. Introduced by Baldwin et al. in 1959, UC is a fundamental scheduling problem in power system operations, combining combinatorial optimization (which units to commit) with continuous optimization (optimal power output). UC remains one of the most important and computationally challenging problems in power systems.	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.	Optimal Power Flow (OPF) is a fundamental optimization framework for computing the most economical and secure operating point of an electrical power system. Introduced by Jean Carpentier in 1962, OPF minimizes operational costs (fuel, losses, or other expenses) while satisfying physical and operational constraints. Modern electric grids depend on OPF for real-time economic dispatch, security analysis, and planning, making it one of the most important problems in power systems engineering.	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.
