Problems solved by technology

[0003] Line transmission loss in the micro-grid is inevitable. As the line lengthens, the loss will increase. Excessive loss in the micro-grid will have a great impact on the balance of supply and demand. In severe cases, it will cause large-scale power outages. Therefore, how to consider transmission loss Maintaining the balance between power supply and demand is a very challenging issue

Abstract

The invention provides a power system load scheduling method considering line transmission loss. The method comprises the following steps: firstly, establishing a power system power balance model based on the distributed control principle, then setting initial power values of nodes, and establishing a node interconnection matrix according to the constraint conditions of the nodes; then, updating the power values of the nodes by using the node interconnection matrix and the initial power values to obtain stable power values of the nodes; and finally updating the method by considering the line transmission loss condition to obtain a new method satisfying the constraint conditions and considering the line transmission loss at the same time, and calculating the power values of the nodes again. And example analysis is provided to test the correctness of the provided method.

Description

technical field [0001] The invention relates to a power system load scheduling method considering line transmission loss, belonging to the field of power system load scheduling. Background technique [0002] The distributed control system is developed on the basis of computer supervisory control system, direct digital control system and computer multi-level control system. Multiple computers separately control multiple control loops in the production process, and at the same time can centrally obtain data, centralize Automatic control system for management and centralized control. It has high reliability, openness, flexibility, coordination and easy maintenance; compared with the traditional centralized control system, the distributed control system can improve the reliability of the control, and the entire system will not be lost due to computer failure. Control; when the management level fails, the process control level still has independent control capability, and the fa...
