Summary:This paper presents an approach for solving the Unconstrained Economic Dispatch Problem (UEDP) in power systems considering a multibus model. The problem is adapted numerically and solved via a Holomorphic Embedding Method (HEM). The HEM methodology was proposed recently in power system to solve the power flow problem. The technique is adapted in this work for solving directly the nonlinear equation system that arises when the UEDP lossy optimization problem is solved. In order to demonstrate the efficacy of the approach, experiments are carried out on the well known IEEE 9-bus test-system. The performance of the proposed technique is evaluated by using the classical Newton-Raphson method. The methodology presents performance more accurate than the Newton-Raphson method.
