Table 3: The output of each REG station in the current and next period/MW. Figure 7: Probability that each REG station can achieve the expected output. significant advantages in terms of completion probability compared to other section margin allocation methods. We analyzed the situation where, after the allocation of section margins, the actual power transmitted by the section of the cluster due to increased load within the REG cluster is lower than the upper limit of the power that can be transmitted by the section, resulting in the section being underutilized. Under the current operation mode, the REG cluster load increase space is 4 MW, thus setting up two scenarios where the actual transmission power of the outgoing section decreases from 270 MW to 267 MW (scenario 1) and 262 MW (scenario 2) due to the increase in cluster load. We calculated the probability that the section margin allocation method proposed in this paper and other section margin allocation methods will be able to complete the output command at each REG station. Before the dispatch center carries out the next section margin allocation, in order to solve the problem of the underutilization of the section due to the rising load of the renewable energy generation cluster, the dispatch center should, based on the difference between the actual power delivered by the section and the upper limit of the power that can be delivered by the section, give instructions to each REG station in the cluster to increase the output as soon as possible, so as to make full use of the delivery section of the REG cluster. The REG stations are dispatched according to the principle of the equal ratio of the installed capacity, which is easy to calculate, so that the REG clusters can make full use of the outward transmission section. The probability of each margin allocation method being able to complete new dispatch instructions from the dispatch center for each REG station in response to the underutilization of the section due to cluster load growth is shown in Table 5.  
As can be seen from the data in Table 5, the proposed section margin allocation method in this paper still maintains a high probability in terms of the ability of each new energy site to respond to dispatch instructions compared to other methods when the actual transmission power value of the section is reduced due to the rising load of the renewable energy generation cluster and the capacity of the section is not fully utilized.
