Abstract

The invention discloses an energy block-type control method and system of a flexible load. The method is used for a cloud server and comprises the steps of dividing power utilization equipment to forma plurality of energy blocks according to types of power utilization equipment, a power utilization place and a power utilization time frame; acquiring a first load characteristic value of a power transmission line and second load characteristic values of the plurality of energy blocks; setting a dynamic threshold parameter of each energy block according to the first load characteristic value andthe second load characteristic value; and sending each dynamic threshold parameter to a corresponding load control terminal, and controlling power utilization equipment connected with the negative control terminal by controlling the negative control terminal according to the dynamic threshold parameter. The dynamic threshold parameter of each negative control terminal can be flexibly set according to states of the first load characteristic value of the power transmission line and the second load characteristic values of the plurality of energy blocks, the corresponding negative control terminal is controlled according to each dynamic threshold parameter, so that the power utilization equipment connected with each negative control terminal is accurately controlled by the negative control terminal.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to an energy block control method and system for flexible loads. Background technique [0002] With the rapid development of the national economy, the demand for electricity continues to grow, so the scale of the power grid and the load of electricity continue to increase. During the operation of the power grid, the transmission line will often fail, and the failure of the transmission line will bring safety hazards to the transmission system. For example, when the high-voltage direct current transmission line fails, the frequency and voltage of the transmission system will drop sharply. , obviously, this will affect the stable operation of the transmission system. Therefore, in the new situation of UHV power grid and large regional power grid interconnection, controlling the flexible load of the transmission system, so that the coordinated distribution of flexible load can ens...
