Abstract

The invention provides an integrated energy system hierarchical distributed coordinated control method for grid clipping. The method divides the energy system into an upper layer control system and a lower layer control system, The method includes the following steps that 1) the lower control system performs self-optimization control on the users; 2) the upper layer control system acquires the power information of a gateway and determines whether the overall peak value of the energy system meets the actual needs; 3) the upper layer park increases the straightening energy storage output and generator output; 4) the upper layer control system determines whether the gateway power is off-limit again; 5) the upper layer control system sends instructions to the adjustable users at the lower layer and interactive users reasonably adjust their own loads; 6) the upper layer control system continuously determines whether the gateway power is off-limit; and 7) the upper park control system sends instructions to the interruptible users at the lower layer, and the interactive users reasonably interrupt their own loads. According to the invention, the problem that a plurality of kinds of energy is difficult to mutual coupling and coordinated complementation can be solved, the peak-load shifting can be realized, and the friendly interaction with the power grid can be realized.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a hierarchical distributed coordinated control method for a power grid peak-shaving comprehensive energy system. Background technique [0002] Energy is an important material basis for the development of the national economy and occupies an extremely important strategic position in the national economy. People's production and life cannot do without energy. With the development of economy and society, the problem of energy shortage is becoming more and more serious, and the supply of conventional fossil energy is increasingly insufficient. At the same time, a series of environmental pollution problems caused by excessive use of fossil energy seriously threaten the survival and development of human beings. [0003] In traditional energy systems, cooling / heating / electricity / gas are often designed, planned, operated, and controlled independently of each other, and different energy suppl...
