ABSTRACT: This paper proposed a
hybrid control model-based voltage control of Hybrid Energy System (HES) that
includes both solar and wind energy conversion systems. The proposed hybrid
voltage control model is the combination process of both the Artificial Bees
Colony algorithm (ABC) and Proportional Integral controller (PI). The novelty
of the proposed method is intelligent foraging behavior of honey bee swarm,
which provides random reduction and ability to adapt complex optimization
problems. Here, the ABC optimizes the gain parameters under various operating
conditions using the minimized Square Error (SE). It considers the actual
voltage outcome of the buck converter and the set point voltage. By using the
optimized gain parameters, the PI controller is operated. Each separate energy
conversion system is controlled by the separate proposed hybrid voltage control
model. The proposed method is implemented in MATLAB/Simulink platform and the
performance is verified using the comparative analysis with the existing
techniques. The comparison results prove the superiority of the proposed
method.
