| Abstract: |
| The load characteristics of urban distribution network under electric energy replacement are analyzed, and the active loss calculation formula is deduced according to the power flow calculation equivalent circuit of on-load voltage and capacity regulating distribution transformers. Then taking the minimum power loss of the whole network as the objective function, a dynamic optimization model of energy-saving and loss reduction for urban distribution networks with on-load voltage and capacity regulating distribution transformers is proposed, which is solved by the parallel cooperative co-evolutionary differential evolution algorithm to obtain the action schemes of equipment such as on-load voltage and capacity regulating distribution transformers. The effectiveness of the proposed model is verified by simulation analysis of a practical 55-bus distribution network. |
