Research on the Cooperative Regulation Technology of Distributed Resource Cluster

In view of the problems of reverse overload, voltage limit and insufficient regulation capacity faced by power grids in areas with high permeability, First proposed a distributed resource cluster collaborative regulation architecture, Including the cluster synergy layer and the platform area autonomous layer; Secondly, the indexes of strong coupling, weak coupling between clusters and power balance are constructed, And according to this to establish a multi-target cluster division model; Again, the cooperative regulation method with the node voltage deviation and the minimum system loss is proposed; Finally, the actual power grid of a 169 node (distributed photovoltaic installed capacity of 1149.79kW, PV permeability of 156<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">%</sup>), for example, Divided into six clusters by iterative optimization, The voltage limit problem is eliminated, The total voltage deviation throughout the day decreased by 17.08<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">%</sup> from the original, The maximum deviation was decreased by 56.25%, Network loss decreased by 28.13 % compared with the traditional control, Photovoltaic utilization rate increased by 7 percentage points. This technology can effectively eliminate the voltage limit, reduce the network loss and improve the consumption rate of distributed resources, promote the transformation of the power grid control mode, and help to achieve the “two-carbon” goal.
