Firefly analytical hierarchy algorithm for optimal allocation and sizing of DG in distribution network

<span lang="EN-MY">Distributed generation (DG) can be beneficially allocated in distribution power systems to improve the system's efficiency. However, specious DG's allocation and sizing may cause more loss voltage profile issues for feeders. Therefore, optimization algorithms are vital future intelligent network planning. Hence, this study proposes a multi-objective firefly analytical hierarchy algorithm (FAHA) determining optimal of DG. The function formulation is improved further by integrating process (AHP) with FA obtain weight coefficient factor (CF). performance proposed approach verified on 118-bus radial different bus at DG location (VDG) as regulated PV-bus during load flow calculations. calculated CF impact unregulated objectives have been analysed. findings show that techniques could allocate most deviation while minimizing improving distribution’s stability index (VSI). experimental results indicate able overall profile, especially PQ-buses, minimize network's simultaneously.</span>
