Description
technical field [0001] The invention relates to a dynamic reactive power control technology, in particular to a daily real-time based dynamic reactive power optimization method. Background technique [0002] Daily real-time dynamic power system reactive power optimization means that within a day, when the load parameters, line parameters and power parameters in the power system are constant, and the system variable constraints (five variable constraints) are satisfied at the same time, by adjusting the size of the control variable , that is, the generator terminal voltage, the number of switching groups of the reactive power compensation device and the tap position of the transformer, so that the active network loss of the system can be minimized. In addition to the above basic measures, it also includes intelligent algorithm optimization and big data processing and analysis process, which optimizes the entire system operation process, and applies optimization ideas to actua...
