The invention discloses a multi-target
plant level
load optimization method based on immune optimization and
fuzzy decision in the technical field of energy-saving power generation. The multi-target
plant level
load optimization method comprises the steps that a thermal power
plant coal consumption model, a model of time needed for completing distributed loads, and a
nitric oxide emission model are established respectively;
coal consumption characteristic parameters, current bearing loads, permitted load change rates and
nitric oxide emission characteristic coefficients of all units in a thermal power plant are determined; constraint conditions of the models are determined, including upper limit and
lower limit constraint conditions and balance constraint conditions of active power; a solution set including the active power of all the units in the thermal power plant, thermal power plant
coal consumption, time needed for completing the distributed loads of the thermal power plant, and the
nitric oxide emission of the thermal power plant is obtained through an immune multi-target
algorithm; an optimal solution is selected from the solution set to serve as output power of all the units in the thermal power plant. According to the multi-target
plant level load optimization method based on immune optimization and
fuzzy decision, the immune multi-target
algorithm is used for realizing multi-target
plant level load distribution, an optimal power distribution scheme for the power plant units is decided according to a
fuzzy decision theory, and therefore the computational process is faster and more accurate.
