Abstract

This paper proposes an efficient real-time approach based on Optimality Condition Decomposition (OCD) technique to solve dynamic economic dispatch (DED) problem. Ramp-rate limits, prohibited operation zones (POZs) constraints, along with transmission losses are considered in the studied DED model. In order to examine the effectiveness of the proposed approach, it is implemented on 5-unit and 54-unit test systems. The obtained results verify applicability of the proposed method for solving the DED problem in real-time environment.
