Optimization of energy management in parallel hybrid vehicles based on dynamic programming algorithm

Abstract

In this paper, the P&O algorithm in the technique of controlling maximum power
point trackers applied in inverters to obtain the maximum power generated from the solar
system is presented. Solar panels have non-linear voltage and current characteristics that depend
on temperature and irradiance reaching PV panels and PV arrays have a unique point of being
able to generate power maximum at each time point. The characteristics of solar radiation
reaching the photovoltaic system are not stable at sunny times of the day, it is often changed by
other factors such as partial cloud cover, total cloud cover or intensity, radiation varies by hour,
by day and by season. As a result, the conversion of photovoltaic energy into electricity of PV
panels will be changed. The power generated by the PV system is unstable, leading to low
conversion efficiency. The application of algorithms in MPPT control technique to find the
point that can generate the maximum power at any time in order to maximize the power received
from the solar system. This paper will present simulation results to prove the correctness of the
proposed method.
