A photovoltaic distributed power output before optimization

The present invention discloses a photovoltaic distributed power output before optimization, autoregressive moving average model by designing the linear prediction parameter obtained before the time-temperature, light intensity, and has recently electricity load; mathematical modeling to arrive at the photovoltaic Distribution power output before; it has distributed power output of photovoltaic power load and has incorporated power flow calculation; simplified flow distribution grid loss loss calculated approximate quadratic formula, according to the quadratic approximation loss The formula is introduced sequence quadratic optimization methods to optimize their distributed power output has to reach the distribution network to minimize loss purposes. The present invention improves the accuracy of the prediction, and the ambient temperature, light intensity and power load forecasting such that the power output of PV may be dynamic scheduling distributed according to a change in the weather, and electricity load, the losses derived quadratic approximation formula binding sequence quadratic optimization method improves the net loss calculation efficiency, ease of engineering practice.
