Problems solved by technology

[0004] In the literature on sensitive loads, most studies are aimed at the evaluation of the sensitivity of sensitive loads and the impact of voltage sag on sensitive loads, and do not consider the impact of voltage withstand capacity of sensitive loads on power distribution. Influenced by network planning, the planning model is not accurate enough
In the long run, the existing network frame planning scheme will not be able to meet the needs of future load development

Embodiment Construction

[0021] The derivation process of the technical solution of the present invention is introduced below, and the derivation result is verified by using an embodiment.

[0022] 1.1 Calculation of sensitive load failure probability-voltage amplitude curve

[0023] Different sensitive loads have their own sensitivities and have different voltage withstand curves. The voltage withstand capacity of sensitive loads will change with time and space. Through simulation experiments, the voltage withstand capacity of various sensitive loads can be obtained. curve, there have been many studies on the evaluation of the sensitivity of sensitive loads to voltage sags. The voltage withstand curve (VTC curve) of sensitive equipment such as figure 1 shown. where U min , U max are the minimum and maximum voltage sag amplitudes that can cause probabilistic losses to sensitive loads, T min , T max are the minimum and maximum sag durations of voltage sags that can cause probabilistic losses to s...

Abstract

The invention discloses a power grid planning method considering load sensitivity classification and probability loss. The load loss caused by voltage fluctuation is taken into consideration in the distribution network planning model, and a new objective function is constructed, which improves the planning model. Accuracy, improved distribution network planning scheme, in line with the needs of future load development.

Description

technical field [0001] The invention relates to the technical field of distribution network planning, in particular to a distribution network planning method considering load sensitivity classification and probability loss. Background technique [0002] As distribution network planning mainly considers economic factors, focusing on the reduction of network cost and network loss, the existing technology uses the cost of load loss as an index to evaluate the reliability of distribution network, but this index cannot be quantified. , the evaluation is not accurate enough, and does not consider the load situation in the distribution network. Some devices are less affected by voltage sags, such as incandescent lamps, while others may not work properly. For such load equipment in the distribution network, if the voltage changes or suddenly changes, it will not work properly or its function will decline. This type of load is called sensitive load or sensitive equipment, such as co...
