Abstract

The invention relates to an active power distribution network operation optimization method considering microgrid active optimization. The method comprises the following steps: S1, establishing a microgrid independent optimization model; S2, establishing an active power distribution network operation optimization model in combination with the microgrid independent optimization model; S3, solving the active power distribution network operation optimization model by adopting a DDPG method to obtain an active power distribution network operation optimal solution; S4, correspondingly outputting the optimal operation solution of the active power distribution network to a power flow control center and a microgrid control center of the active power distribution network so as to optimize the operation state of the active power distribution network. Compared with the prior art, the active power distribution network optimization model considering multi-microgrid active optimization is established and is solved through the DDPG method, so the multi-control-center optimization problem is solved, and the active power distribution network can be optimized in real time.

Description

Technical field [0001] The invention relates to the technical field of power distribution network operation optimization, and in particular to an active power distribution network operation optimization method considering the active optimization of microgrids. Background technique [0002] In the active distribution network (ADN), distributed generation (DG) is usually connected to the distribution network in the form of multiple microgrids (MG). Control and management in order to realize the power flow management and voltage control of the distribution network, so that after multiple microgrids are connected to the active distribution network, to a certain extent, it can alleviate the node voltage of the distribution network caused by a high proportion of random fluctuations of distributed power. Over-limit, increased network loss, and power fluctuations on the tie-line of the distribution network. [0003] At present, the ownership of distributed power in the distribution networ...
