Embodiment Construction

[0069] The following takes the IEEE 69 node system as an example to illustrate a probability analysis method for distributed power planning based on area gray relational decision-making.

[0070] The present invention is a probability analysis method for distributed power planning based on area gray correlation decision-making, which includes:

[0071] refer to figure 1 and figure 2 , 1) Calculate the deterministic power flow

[0072] (1.1) Calculate the LSFs, VSI, and IVM values ​​according to formula (1), formula (2), and formula (3). The calculation uses area gray relational decision-making to carry out comprehensive weighting on the three methods of LSFs, VSI, and Index, and obtains the value of the probability analysis method AGIDM for distributed power planning based on area gray relational decision-making, as shown in Figure 5 shown. Select the top 10 of the ranking results as the candidate access nodes of the DG.

Description

technical field [0001] The invention relates to a distribution network distributed power supply, which is a probability analysis method for distributed power supply planning based on area gray correlation decision-making, and is applied to distribution network distributed power supply (Distribution Generation, DG) planning. Background technique [0002] DG planning generally includes two tasks: site selection and capacity determination. According to different planning objectives, different planning methods can be used to optimize the optimal planning scheme in different scenarios. Existing planning methods are mainly divided into two categories: classical methods and artificial intelligence algorithms. However, as the scale of the distribution network increases, it takes a long time to plan using the classic method and the convergence speed is slow; artificial intelligence algorithms have been widely used in the DG planning of the distribution network, but as the scale of t...
