Embodiment 1
[0048] This embodiment adopts a power system power flow optimization method that takes into account the IPFC control characteristics of double-circuit lines according to the present invention. The optimization method includes two parts: objective function and constraint conditions.
[0049] (1) Objective function
[0050] For taking into account the safety and economy of the system, the method of the present invention sets up the objective function as follows:
[0051] f=λ 1 f 1 +λ 2 f 2 (1)
[0052] where f 1 is the security objective function, f 2 is the economic objective function. lambda 1 , lambda 2 are the weight coefficients corresponding to the security objective function and the economical objective function, respectively.
[0053] In order to make the optimization strategy meet the N-1 safety constraints of the power flow, the present invention introduces the sum of the load rates of the heavy-duty lines when N-1 faults occur to describe the safety object...
