Kokkuvõte	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.	The Fast Decoupled Load Flow (FDLF) method, introduced by Stott and Alsac in 1972, exploits the weak coupling between active and reactive power in power systems to accelerate convergence beyond standard Newton-Raphson. By decoupling the equations and using constant, approximate Jacobians, it reduces computation per iteration while maintaining acceptable accuracy for most practical systems. This method remains widely used in operational software for its speed and numerical stability.	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.
