Example Embodiment
[0046] Hereinafter, in conjunction with the accompanying drawings, a preferred embodiment is described in detail to further illustrate the present invention.
[0047] The present invention is a method for evaluating user sag economic loss based on the synthesis of multiple quality loss functions, including:
[0048] Voltage sag economic loss classification of power users: The voltage sag is defined as follows: a phenomenon in which the amplitude of the power frequency voltage in a power system drops to 0.1 to 0.9 p.u, and the duration is 10 ms to 1 min. Because there is a parallel or series relationship between economic activity links, when a certain series link or all parallel links of economic activity stop working due to a voltage sag event, the economic activity will be interrupted, and vice versa. Accordingly, according to the description of the economic loss of users' voltage sag in GB / Z32880.1-2016, they are divided into the following two categories:
