A modified shuffle frog leaping algorithm for multi-objective optimal power flow

Niknam, Taher; Narimani, Mohammad rasoul; Jabbari, Masoud; … - In: Energy 36 (2011) 11, pp. 6420-6432

This paper presents an efficient and reliable evolutionary-based approach to solve the Optimal Power Flow (OPF) problem … determining electricity prices. Therefore, the conventional optimal power flow cannot meet the environmental protection … requirements, because it only considers generation cost minimization. The multi-objective optimal power flow considers economical …
