Abstract

The invention discloses a high-permeability active power distribution network electric energy quality management method based on FCS-MPC control. The method comprises the steps of building a high-permeability active power distribution network as a power quality management test system; building an adjustable reactor mathematical model; combining the finite state model prediction control FCS-MPC with an adjustable reactor model, constructing a step length function, and predicting the output of an adjustable reactor; and setting a self-adaptive weight selection method of the FCS-MPC so that the FCS-MPC can judge according to the severity of the power quality disturbance to output an optimal switching state. According to the method provided by the invention, the adjustable reactor is used forcomprehensively treating the composite power quality disturbance of the high-permeability active power distribution network, meanwhile, after the adjustable reactor is combined with the FCS-MPC, different disturbance types can be controlled and treated, and a new control strategy for the adjustable reactor is provided; therefore, self-adaptive weight factor determination can be carried out according to the amplitudes of the voltage and the current and the harmonic distortion rate, and the multi-objective optimization is completed.

Description

technical field [0001] The invention relates to the technical field of power quality control, in particular to an FCS-MPC control-based power quality control method for high-permeability active distribution networks. Background technique [0002] The active distribution network can give full play to the performance of the distributed power generation system, improve the reliability of power supply for users, and weaken the impact and negative impact of distributed power on the power grid, which has good economic and social benefits. Due to the diversity of active distribution networks in terms of power sources, loads, energy conversion units, energy storage, and operating states, the intermittence and randomness of distributed generation, and the high penetration rate between large power grids and active distribution networks, The power quality problem of the active distribution network is much more serious than that of the traditional large power grid. The main manifestati...
