Economic Load Dispatch with Security Constraints of the Algerian Power System using Successive Linear Programming Method
نویسندگان
چکیده
This paper presents a solution of the economic load dispatch (ELD) problem with security constraints of power systems, using an iterative technique based on the linear programming method, called Successive Linear Programming (SLP). The objective is to minimize the nonlinear function which is the total fuel cost of thermal generating units, while taking into account the security constraints (power generations, voltages and line flows). The proposed approach has been implemented on the Algerian 59-bus system. Simulation results obtained from the proposed method confirm the advantage of computation rapidity and solution accuracy. The comparison results prove the capability of the proposed method in real-time implementation for the economic load dispatch problem.
