Economic Load Dispatch

These files are provided for the studying the economic load dispatch of power system.

The problem of economic operation of a power system or optimal power flow (OPF) can be stated as—allocation of the load (MW) among the various units of generating station and among the various generating stations in such a way that, the overall cost of generation for the given load demand is minimum. This is an optimization problem, the objective of which is to minimize the power generation cost function subject to the satisfaction of a given set of equality and inequality constraints. The problem is analyzed, solved and then implemented under online condition of the power system. The input data for the problem comes from conventional power flow study.
