The present invention provides a method and system for network loss and reactive power coordination optimization. The method includes: monitoring the load data of each node in a preset area to obtain a typical load curve of the preset area; The curve is segmented, and the breakpoints of the segments are extracted; according to each breakpoint, the load curves are grouped to obtain multiple groups; the optimization algorithm is used to optimize the network loss and reactive power of each group, and the optimization result is obtained. By detecting the load data of each node in the area, the typical load curve is obtained and segmented, and then the segmented breakpoints are extracted for grouping, and finally the optimization target is determined, and the network loss and reactive power optimization of each group is performed using the optimization algorithm , solves the overly complicated problem of multi-time-point joint optimization, realizes the division of the global load into time periods, optimizes each time period, effectively reduces the amount of calculation, and further ensures the stable and efficient operation of the power grid.
Description
technical field [0001] The invention relates to the field of distribution network analysis and control, in particular to a network loss and reactive power coordination optimization method and system. Background technique [0002] The frequent fluctuation of the load in the distribution network has caused certain difficulties to the operation control of the distribution network. The reactive power optimization method is an effective method to solve this situation. The reactive power optimization method is to use the multi-objective optimization method to control the distribution network. It is an effective method to optimize and adjust reactive power compensation equipment to achieve minimum network loss and stable voltage. Due to the time-varying nature of the load, the optimal result cannot be achieved by reactive power optimization based on a single load at a single time point. Moreover, due to the high complexity of the optimization problem, the complexity of multi-time p...
