Optimal Environmental Economic Dispatch Using a Classical Technique

Abstract

This paper presents a classical technique based on co-ordination equation to solve Environmental Economic Dispatch (EED) problem, considering nonlinear characteristics of the generator such as Ramp Rate limits and Prohibited Operating Zones. The multi-objective EED 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 the generating units. The approach includes the evaluation of trade-off curve between fuel cost and emission level 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
