Embodiment Construction
[0042] (1) Each distributed power source in the i-th voltage control group sets the initial value of the active power utilization rate β pi,j (0); where i=1,2,...,n; j=1,2,...,N i ; n and N i Respectively, the total number of voltage control groups and the total number of distributed power sources in the i-th voltage control group; start iterative calculation;
[0043] (2) The active power utilization rate β of the j-th distributed power generation in the i-th voltage control group after the k-th iteration pi,j (k) is calculated as:
[0044]
[0045] In the formula: k=1,2,..., is the number of iterations; β pi,j (k) is the active power utilization rate of the jth distributed power generation in the ith voltage control group after the kth iteration; β pi,m (k-1) is the active power utilization rate of the mth distributed power generation in the i-th voltage control group after the k-1th iteration; d pi,j It is the identification of the voltage monitoring distributed pow...

The present invention relates to the technical field of distribution network distributed optimization control, in particular to a distribution network distributed optimization control method for distributed power supply grouping cooperation, specifically, the distributed power supply in the distribution network is divided into a power control group and a power control group. Multiple voltage control groups, each voltage control group uses a distributed consensus algorithm to exchange active power utilization, to achieve optimal control of a node voltage; the power control group uses a distributed consensus algorithm to exchange active power utilization, the distribution The active power exchanged between the grid and the external grid is controlled as a given value. The optimal control method realizes the optimal control of multiple targets in the distribution network in a distributed manner, and has strong scalability, high robustness, and high reliability optimization, and is very suitable for power distribution with high penetration rate distributed power access Network optimization runs.
Description
technical field [0001] The invention relates to the technical field of distributed optimization control of distribution network, in particular to a distribution network distributed optimization control method of distributed power supply group cooperation. technical background [0002] The access of a large number of distributed power sources is an inevitable situation for the development of the distribution network in the future. The traditional centralized control method based on SCDA system has the disadvantages of large amount of data acquisition and processing, poor scalability and low reliability, so it cannot continue to play a role in the optimal control of distribution network connected to a large number of distributed power sources. The distributed optimization control method does not require a centralized controller, and has strong system scalability and control robustness. It has been widely used in engineering fields such as UAV formation control and robot coordi...
