Abstract

The invention provides a method for optimizing a generator set. The unit combination optimization of the present invention is a double-layer optimization problem. The first-level optimization is a unit input optimization problem. The improved genetic algorithm is used to optimize the unit input. On the basis of the determination of the unit input, the second-level optimization is performed. Optimization is the optimization of unit output, which is solved by quadratic programming, and the result of quadratic programming is used as a fitness function to further affect the evolution of individuals in the genetic algorithm. The method can efficiently and quickly optimize the unit combination for the power company, reduce energy consumption, facilitate unit maintenance, prolong the life of the generator, and provide high-quality electric energy for the society. The improved genetic algorithm has the characteristics of global convergence, smoothness, faster convergence and more robustness, and it is more suitable for optimizing unit combination optimization when combined with quadratic programming.

Description

technical field [0001] The invention belongs to the field of generator unit optimization, and in particular relates to an optimization method for synergistically optimizing unit input and unit output. Background technique [0002] The unit combination problem refers to optimizing the start-up and shutdown plan that satisfies various constraints reasonably within a period, so as to minimize the total operating cost of the unit, minimize the energy consumption of the unit in the entire period, and thus operate economically. Combinatorial optimization can greatly improve the operating efficiency of the power system. This is a unit combination optimization problem, which has always been a hot and difficult point in the power system. The problem of unit combination mainly has two aspects. One is the unit combination. Considering the constraints of system capacity and backup, power balance constraints, and upper and lower limits of generator output power, optimize and determine t...
