Problems solved by technology

[0002] As loads such as distributed power and electric vehicles are connected to the distribution network, the existing distribution network evaluation and analysis work can no longer be well adapted to the active distribution network.
Distribution network evaluation has the characteristics of complex business, large amount of information, and multiple application levels. The existing distribution network evaluation and analysis methods are relatively low in intelligence, require manual data extraction, rely heavily on professional and technical personnel, and are time-consuming and laborious. Poor evaluation stability and repeatability, unable to meet the needs of the power grid for guaranteed load development, reliable power supply, and improved utilization efficiency

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] After verifying and repairing the distribution network data and power data, the power grid evaluation is performed, such as figure 1 As shown, the active distribution network evaluation method of the present invention includes the following steps:

[0020] 1) Set three types of power grid evaluation indicators: technical, economic and resource;

[0021] Technical grid evaluation indicators are used to evaluate grid power supply capacity and grid structure indicators, which include basic indicators reflecting grid power supply capacity and grid structure and derivative indicators reflecting the coordination and matching characteristics of power grids at all levels; economic grid evaluation indicators are used to evaluate power grid Asset operation level and operation efficiency, including basic indicators reflecting the operation level and effici...

Abstract

The invention relates to an active power distribution network assessment method. The active power distribution network assessment method comprises the following steps: setting three categories of power distribution network assessment indexes, namely technology, economy and resources; refining the set technical, economic and resource power distribution network assessment indexes, and calculating each index; dividing various indexes according to the benefit type, the cost type, the interval type and other types, calculating to obtain the score of each index in the benefit type, the cost type and the interval type by constructing a subordinate function and combining a result value of each index, and setting the score of each index in the other types as 100; carrying out weighted average on the score of each index by adopting an AHP (Analytic Hierarchy Process), and calculating to obtain a comprehensive assessment value of an active power distribution network in a certain region; repeating the steps to obtain a comprehensive assessment value of the power distribution network of each region, and comparing the comprehensive assessment values of the active power distribution networks in all the regions, wherein the high comprehensive assessment value indicates that the comprehensive level of the active power distribution network in the corresponding region is high.

Description

technical field [0001] The invention relates to a distribution network evaluation method, in particular to an active distribution network evaluation method. Background technique [0002] As loads such as distributed power generation and electric vehicles are connected to the distribution network, the existing distribution network evaluation and analysis work can no longer be well adapted to the active distribution network. Distribution network evaluation has the characteristics of complex business, large amount of information, and multiple application levels. The existing distribution network evaluation and analysis methods are relatively low in intelligence, require manual data extraction, rely heavily on professional and technical personnel, and are time-consuming and laborious. Poor evaluation stability and poor repeatability cannot meet the needs of the power grid for guaranteed load development, reliable power supply, and improved utilization efficiency. [0003] In or...
