To optimize the operation of power system, it is necessary to establish security constrained economic dispatch(SCED) and introduce locational marginal pricing(LMP)method.
For a given load demand, security economic dispatch (SED) allocates the units generation to minimize the total production costs, including the security and load flow equation constraints.
