Description
technical field [0001] The invention relates to an operation control method of a distribution network, in particular to a method and equipment for optimal operation of reactive power and voltage of a distribution network based on SSA-PSO fusion. Background technique [0002] The distribution network is the link between the transmission system and end users, and is one of the core components of the power system. The quality of the distribution of reactive power in the distribution network will directly affect the voltage quality of each node of the system. This is not only directly linked to the user's electricity experience, but also affects the safety and economy of the entire grid operation. [0003] If the reactive power is insufficient, it will cause the system voltage to be low, resulting in an increase in the active network loss. In this case, if some unexpected disturbances occur in the system, it is likely to cause the system voltage to fall below the lower limit v...
