Abstract: The intermittent new energy’s large-scale access to the grid will have a significant impact on the grid, especially bring challenges to the regional power grid dispatch operation and peak load regulation during the summer high temperature heavy load period. Taking the load characteristics of the Wuhu summer power grid and the intermittent new energy output characteristics for the research object, this paper studied on the correlation between the intermittent new energy and the summer load in the Wuhu area and carried out statistic analysis of the impacts of intermittent new energy on the comprehensive load and peak load regulation of Wuhu summer power grid. The conclusion can provide reference and guidance for the future large-scale intermittent new energy access to regional power grid peak summer and new energy dispatch management.
Key words: intermittent new energy; load characteristic; output characteristics; correlation; peak load regulation
