Abstract

Abstract This paper presents a classical technique based on co-ordination equation to solve Combined Economic and Emission Dispatch (CEED) problem, considering nonlinear characteristics of the generator, such as ramp rate limits and prohibited operating zones. The multi-objective CEED problem is converted into a single objective problem using a modified price penalty factor approach. In this paper, incremental cost is heuristically updated iteratively, which makes the solution independent of the number of generator units. The approach includes the evaluation of trade-off curve between the fuel cost and the emission according to the multi-objective function. The performance of the proposed method is demonstrated using modified IEEE 14 and 30 bus systems with different loading conditions.
