The effect of large-scale electric heating heat storage load coordinated operation on abandoned wind consumption

Large-scale electric heating heat storage load is of great significance for eliminating wind and abandoning wind. However, power grid dispatching needs to coordinate these different types and different capacity loads so that it does not affect its own safe operation. The grid plays a bigger role. To this end, the large-scale electric heating heat storage load is divided into two categories: one is distributed small capacity; the other is centralized large capacity. The two load operation characteristics are modeled, and a coordinated operation strategy of two loads is proposed. The calculation of the actual data of a provincial power grid shows that the distributed has the characteristics of timing and fixed amplitude, and the centralized has the characteristics of dynamic adjustment. The distributed consumption is the low-level electricity, which can improve the ability to dissipate the wind and improve the peaking capacity of the power grid; most of the centralized consumption is the abandonment of wind power, but also can improve the dynamic peaking ability of the power grid.
