Research on Optimal Scheduling Strategy of Active Distribution Network Based on Multi-source Cooperation

To prevent the ADN model from falling into the local optimum and slow convergence speed in the optimization solution, this paper establishes an active distribution network scheduling priority and distribution network scheduling coordination control framework considering multiple coordination under the premise of meeting various network constraints and ensuring the reliability of distribution network. Then, aiming at the active distribution network with multiple sources and load, the mathematical models of reactive power compensation device and on load tap changer are established. In the case of meeting the constraints, the improved AHP algorithm is used to solve the model. To verify the effectiveness of the distribution network scheduling model and the algorithm, the improved IEEE-33 bus system simulation is adopted. The results show that the multi-source collaborative optimization scheduling can effectively improve the energy consumption rate, load fluctuation, network loss and other indicators, and achieve the economic and security scheduling standards of the optimization cycle.
