A Flower Pollination Algorithm Approach or Optimal Reactive Power Dispatch

This paper proposes an effective and robust evolutionary optimization technique, known as the Flower Pollination Algorithm (FPA), to address the Optimal Reactive Power Dispatch (ORPD) problem in power systems. The performance of the proposed FPA is evaluated using the standard IEEE 30-bus test system, where control variables include bus voltages, transformer tap settings, and reactive power
sources. The objective functions considered are the minimization of active power transmission losses, total voltage deviation, and enhancement of the voltage stability index. The results obtained using FPA are compared with those from other recently developed evolutionary algorithms reported in the literature. Simulation outcomes demonstrate that FPA provides superior performance in terms of solution quality, effectiveness, and convergence speed,
making it a promising tool for solving the ORPD problem.
