Linear Hopfield Based Optimization for Combined Economic Emission Load Dispatch Problem

In this paper a linear Hopfield model is used to solve the problem of combined economic emission dispatch (CEED). The objective function of CEED problem comprises of power mismatch, total fuel cost and total emission subjected to equality/inequality constraints. In proposed methodology, inclusion of power mismatch in objective function exhibits the ability of attaining power mismatch to any desirable extent and may be employed for large-scale highly constrained nonlinear and complex systems. A systematic procedure for the selection of weighting factor adopted. The proposed method employs a linear input-output model for neurons. The efficacy and viability of the proposed method is tested on three test systems and results are compared with those obtained using other methods. It is observed that the proposed algorithm is accurate, simple, efficient, and fast.
