Embodiment

[0037] Example: such as figure 1 The shown method for power quality management decision support includes the following steps:

[0038] (1-1) Research: Master the output characteristics of distributed small hydropower and photovoltaic through research;

[0039] (1-2) Determine data processing rules and optimization strategies: According to the historical data of the electricity consumption information collection system excavated by using big data mining technology, determine data processing rules and optimization strategies;

[0040] At the same time, based on the three dimensions of target, time and space, in the target dimension, decompose and coordinate control among multiple targets such as safe and stable operation of the power system, reduce network loss, improve voltage quality, and reduce the number of adjustments of reactive power equipment. In terms of time dimension, economy is reflected in the long process, and voltage safety is reflected in the short process, requ...

Abstract

The invention discloses a method for supporting power quality governance decision. The method comprises the following steps: grasping the output characteristics of distributed small hydropower and photovoltaic through investigation and research; determining a data processing rule and an optimization strategy according to historical data of an electricity consumption information collection system excavated by using the big data mining technology; researching the key technology and the manufacturing technology; manufacturing a prototype; researching an upper layer data platform and the control system technology; and performing power quality integrated monitoring and control technology engineering construction on an active power distribution network. By adoption of the method disclosed by theinvention, the conventional extensive voltage quality management mode is changed, and the method disclosed by the invention has the characteristics of improving the power receiving quality of users,realizing global voltage adjustment and improving the project investment benefit ratio.

Description

technical field [0001] The invention relates to the technical field of distribution network control, in particular to a method for decision support for power quality control that can improve the quality of power received by users, realize overall voltage adjustment, and improve project investment benefit ratio. Background technique [0002] Photovoltaic power stations have the advantages of safety, reliability, and greenness, but they also have certain limitations. Distributed photovoltaic power stations are constrained by conditions such as four seasons, day and night, and weather, and the power generation is unstable. With the rapid development of distributed power sources, a higher The structure of the active distribution network in different forms also brings new problems to the distribution network. [0003] After the distributed power supply is connected to the distribution network, the problem of power quality is more prominent due to the reverse flow of the power sup...
