Cogeneration units usually adopt the “heat based electricity” as the main operation mode in heating season, which will lead to the shortage of peak load regulation capacity and a large number of wind abandonment in power grid. Therefore, a stochastic optimal allocation method of thermal power units is proposed for the uncertainty of wind power output and load. The wind power prediction method based on interval discretization is adopted. On this basis, the chance constraint model of thermal power unit based on wind heat complementary and heat storage device configuration is proposed, and the coordinated scheduling solution strategy based on real coded quantum evolution is proposed. Finally, the proposed coordinated scheduling strategy is applied to typical thermal power units to verify its effectiveness.
