| description | [Introduction] With incessant grid-connection of wind farms and photovoltaic power stations, the development of regional power grid structure cannot keep pace with the growth rate of new energy unit capacity, characteristics of multi-energy mix and hierarchical features of section bring difficulties to the formulation of day-ahead generation scheduling, for this reason, a method for multi-level and multi-energy day-ahead generation scheduling considering the safety constraint of the section and the fairness of dispatch was proposed. [Method] This paper presented a depth-first search for the restricted section, and proposed an output limitation allocation strategy based on information entropy. A fairness calculation method was constructed by using the concept of information entropy in economics to guide the quantitative indicators for evaluating scheduling fairness. [Result] Under the circumstances of ensuring that the cross-sectional current is close to the stability limit, the active power of each power plant is distributed reasonably and equitably, thereby realizes the full utilization of wind and solar resources. [Conclusion] Through a practical example of a regional power grid, it is proved that this method can solve the existing problems in new energy day-ahead generation scheduling and has good practical application value. |
