This paper has been emphasized to develop a new methodology for optimal power flow (OPF) using delicate flower pollination algorithm (DFPA). Being an essential key factor in the ocean of power sector, its operational features and controlling attributes have been making the available power resources to flow in a fair manner. The DFPA, a nature intriguing algorithm, has originated from the pollinating characteristics of flowers. The proposed method has sounded very louder on the global optimum solution using DFPA through propagating the exploitation phase of optimization by considering two test-case studies such as shortened fuel cost and real power loss decrement. Simulation results on IEEE_Standard 30 bus test system have clearly exhibited that the proposed method outperforms the existing numerous strategies. © 2021, Springer Nature Singapore Pte Ltd.
