| 英文摘要 |
| An improved perturbation and observation MPPT algorithm with variable step size and no oscillation in
steady state is proposed in this paper. The improved algorithm not only keeps the basic perturbation and observation
method simple and easy to implement, but also stops the steady-state oscillation and has good tracking speed. The proposed
algorithm firstly achieves fast tracking of the maximum power point by changing the step size. When the steady state is
determined, the artificial perturbation is stopped to achieve stable output power without oscillation, so as to reduce the
power loss caused by oscillation and improve the efficiency of the whole system. When there is an abrupt change in the
external environment, the algorithm can detect the change of working conditions according to the abrupt change of voltage
and current values by using the three-point measurement method, and reset the parameters, so as to reduce the time of
retracing the maximum power point. Due to the randomness and volatility of photovoltaic power generation, energy storage
batteries and photovoltaic modules are usually combined to form a hybrid photovoltaic energy storage system. In order to
match the actual situation, the simulation and experiment of the hybrid photovoltaic energy storage system are carried out
in MATLAB/Simulink in this paper, and the experiment results verify the performance of the proposed algorithm. |
