This paper presents an ecient method to solve an economic load dispatch problem with load flow type network security constraints: the active generation limits and line active power flows limits. A new form of linear programming method is proposed: a variable weights linear programming. The nonlinear dispatch problem is transformed into a linear one through variable weights linear programming. To achieve good linear, representation the nonlinear cost functions between the active generation limits are approximated by the sum of products of cost values multiplied by the variable weights. The nonlinear equality network constraint containing the losses expressed by the specially formulated and calculated function of generated powers is transformed into a linear one, the same manner as above. The set of nonlinear inequality constraints on line active power flows is linearly expressed in terms of active bus generation powers with upper limits on the active power flow to each violating lines. The dispatch problem transformed this manner with or without solving the load flow problem is demonstrated that the proposed method has practical application for real-time control/dispatch.
