Analysis of Differences between Peak-regulated Wind Abandonment and Grid Frame Abandoned Wind in Power Grid

Large-scale clean energy is merged into the power grid. For different grid-connected methods, the reasons for wind abandonment are different. In this paper, it studied peak-regulated wind abandonment and grid frame abandoned wind, and proposed the calculation model and discrimination method of the peak-regulated wind abandonment and grid frame abandonedwind; it also proposed the correlation analysis method of power grid wind abandonment, peak-regulated wind abandonment and grid frame abandoned wind. Combined with the example, the paper analyzedthe relationship between power grid wind abandonment, peak-regulated wind abandonment and grid frame abandoned wind. For the northern heating season, the peak-regulated wind power abandonment is larger. In the non-heating season, the grid frame abandoned wind power is larger, and when the peak-regulated wind power abandonment is larger, the grid frame abandoned wind power is smaller, and the duration of the peak-regulated wind abandonment is smaller than the duration of the grid frame abandoned wind. Because a large number of measures to consumption wind are mainly aimed at peak-regulated wind abandonment, the proportion of grid frame abandoned wind has exceeded 1/3 of the total abandoned wind. It can be seen that the research on abandoning wind should be carried out from the two dimensions of peak-regulated wind abandonment and grid frame abandoned wind.
