Embodiment Construction
[0058] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0059] The overall flow chart of the present invention is as figure 1 As shown, the moth flame method is used to solve the optimal reactive power scheduling problem.
[0060] 1. OPRD mathematical modeling
[0061] 1.1 Objective function
[0062] In the present invention, the objective function of the OPRD problem is to minimize the power loss and voltage deviation of the transmission system under the conditions of equality constraints and inequality constraints. The OPRD problem can be formulated as the minimization of a function f(x,u) as follows:
[0063]
[0064] The function f(x,u) is the objective function. In addition, g(x,u)=0 and h(x,u)≦0 are equality constraints and inequality constraints, respectively. In OPRD, the equality constraints are the power balance equations and the inequality constraints are the generator voltages, t...
