Abstract

The invention discloses a voltage control method based on the coordinated optimization of energy saving and loss reduction of distribution network. Firstly, a static user load model is established, and a coordinated optimization model of energy saving and loss reduction of distribution network is established. Under the same premise, the topology of the original distribution network is simplified, and the improved particle swarm optimization algorithm is used to solve the coordination optimization model of energy saving and loss reduction of the distribution network, and the adjustment parameters of each voltage regulation equipment during the optimization period are obtained. The present invention comprehensively considers the economy of various voltage regulation equipment on the basis of user energy saving and power grid loss reduction, uses simplified topology and particle swarm algorithm to improve calculation efficiency, and realizes the coordination and unification of user energy saving and power grid loss reduction by optimizing the control voltage .

Description

Technical field [0001] The present invention belongs to the field of supply and electrical technology, and in particular, the present invention relates to a voltage control method based on distribution network energy saving and loss coordination. Background technique [0002] With the rapid development of my country's economy, the power grid load is increasing, and people's requirements for power quality are increasing; on the other hand, the reduction in energy and its cost increases, making energy saving reductions into today's social concern. focus. Among the entire power system transmission network, about 96% of the electric energy delivery network comes from the distribution network, the distribution network is directly connected to the user, and the power loss is very large. According to statistical analysis, the line loss electricity volume of 10kV and the following power distribution network accounts for about 78% of the line loss of the entire power network. Therefore, r...
