The invention discloses a probability maximum
load margin multi-target optimization model of an electrical
coupling system and a solving method of the optimization model, and relates to the field of multi-energy-flow
system operation control. The method includes the following steps that the power
system maximum
load margin and the
natural gas system maximum
load margin of the electrical
coupling system serve as multiple targets, the uncertainty of
wind power input is considered, constraint conditions of a power network, a
natural gas network and an EH are considered, and a
mathematical model of probability maximum load margin multi-target optimization of the electrical
coupling system is established; the multi-target optimization model is solved on the basis of SRSM, the Newton method, NSGA-II and the maximum satisfaction decision mixed
algorithm, and the optimal compromise scheduling strategy, corresponding flow distribution and other
data information are obtained. The method is suitable for the development trend of energy
interconnection, and can ensure the high-efficiency and environment-friendly operation of a multi-energy-flow system.
