Fast Matching Method for Key Nodes of Smart Distribution Network Oriented to Operational Optimization Requirements

With large-scale distributed power supply, flexible load and electric vehicle access to smart distribution network, distribution network presents normalized randomness and volatility. Therefore, operation optimization control of intelligent distribution network is carried out. In order to make operation optimization of distribution network more purposeful and pertinent, this paper puts forward a fast matching method for key nodes of intelligent distribution network to meet the requirements of its operation optimization. Taking load rate as the main index reflecting its operation change, a fast matching process of key nodes in intelligent distribution network is designed. By analyzing the influence direction and degree of each node on load rate trend, the key nodes affecting the operation change of distribution network are found to achieve rapid matching and location of key nodes. Finally, some suggestions are put forward for the object of operation optimization. Results show that the proposed method can quickly match and locate the key nodes affecting operation of the intelligent distribution network. Based on relevant suggestions, the load rate of distribution network is improved and optimized, and the node voltage is within allowable range.
