Generation Schedule Generation Method Based on Joint Clearing of Electric Energy and Operational Reserve

In order to solve the problem that it is difficult to guarantee the overall benefit maximization under the stepwise clearing of electric energy and reserve, a generation plan generation method based on joint clearing of electric energy and reserve was studied. From the two dimensions of grid absorption capacity and unit regulation capacity, the coupling characteristics between electric energy and reserve are analyzed. On this basis, combined with the needs of centralized optimization, the coupling relationship between electric energy and reserve is divided into two types: static relationship and dynamic relationship. A centralized clearing model considering the static coupling characteristics is constructed to obtain the electrical energy and reserve operation plan of the generator set. Furthermore, considering the dynamic relationship, the cleaning results are checked until the generation planning results that meet the coupling characteristics requirements are obtained. Finally, a numerical example based on IEEE 30-node system was constructed to verify the effectiveness of the proposed method. The example results show that the proposed method can avoid the problem that the clearing results do not meet the operation requirements caused by factors such as the limit of power grid transmission capacity, and improve the effectiveness of the joint clearing results.
