Abstract

The invention discloses a power generation plan optimizing method for restraining unit reverse regulation in a power plant. On the basis of day-ahead and real-time power generation planning input and output data, the data include system loads, new energy prediction, an overhauling plan, section limit, unit shutdown information, a unit reference plan and information of unit sensitivity to monitoring elements, in comprehensive consideration of various restraints such as the system balance restraint, the unit operation restraint, the network security restraint and the unit group restraint, the mapping relation between a unit and the power plant is maintained on the basis of a common optimizing model, and a unit reverse regulation restraint in the power plant is introduced to form a mathematical model of the unit reverse regulation restraint in the power plant. A more reliable, effective and practical unit output plan is achieved, the execution level of the unit plan is increased, the closed-loop levels of day-ahead and real-time plans and AGC are increased, the power generation optimizing method is beneficial to increasing the intelligentization level of day-ahead and real-time power generation plan dispatching and improving the decision-making capacity, and the increasingly-lean safe operation requirement of a large power grid is met.

Description

technical field [0001] The invention belongs to the technical field of power system scheduling automation, and relates to a power generation plan optimization method for suppressing reverse adjustment of units in a power plant. Background technique [0002] At present, with the widespread implementation of smart grid construction in China, according to the next day's electricity demand forecast, considering various constraints such as system balance constraints, unit operation constraints, power grid operation constraints, and network security constraints, the next day's 96-point unit combination plan is optimized. The practical level of the day-ahead power generation planning function of the power planning and output planning has been comprehensively improved. [0003] In the actual implementation process of the day-ahead plan, due to the large deviation between the day-ahead system load forecast and the day-ahead new energy forecast and the actual situation, the day-ahead ...
