Short Period Fluctuation Compensation using Limitation Control of Photovoltaics by Bidirectional Communication Considering Communication Failure

Abstract

In this paper, photovoltaics (PV) outputs are not only limited constantly but also controlled by bidirectional communications to compensate short period power fluctuations. In this case, if qualities of communication systems are not high, communication failure may not be ignored. The effect of communication failure is evaluated. If communication failure are not very small, tracking performance receives a bad influence. Then, a compensation method of it is proposed. The compensation method uses an adaptive control. It is found that the proposed method can compensate communication failure to some extent by simulation. Short period power fluctuation may be reduced by the compensation method of communication failure.
