[0050] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0051] like figure 1 As shown, the present invention includes the following steps.
[0052] S01: It is determined to evaluate branch load fluctuations based on the load ratio of the maximum number of branches in the power system. Therefore, the objective function of the power supply planning optimization model is as follows:
[0053]
[0054] In the formula, x is the decision vector variable; f(x) is the objective function; P i is the branch load ratio of branch i; is the load ratio of the maximum branch number of branch i. By setting the load ratio to reflect the branch load fluctuation limit, the occurrence of heavy load and light load can be effectively avoided.
[0055]S02: Inheriting the traditional power planning's node active power and reactive power balance constraint h(x)=0, generally a node power balance constraint,...
