A closed-loop control method for power generation planning based on multi-scale approximation of day-ahead planning

Abstract

The invention discloses a day-ahead planed multi-scale imminent generation scheduling closed-loop control method and relates to a generation scheduling closed-loop control method. At present, following up on plans strictly is required on a unit by generation scheduling closed-loop control, and regulating capacity of the unit is limited from a certain extent, and a mass of thermal power generating units are required to input and participate regulation to guarantee area whole control preferences. The generation scheduling closed-loop control method includes the following steps: 1), arranging a master control area module in a interconnection power network system; 2), connecting the master control area module with an automatic generation control module; 3), designedly following the tracks of a model unit, a plan band width model unit and a plan deviation priority model unit by the automatic generation control module. With the technical scheme, the unit is provided with different plan control models according to self needs, multi-scale approaching of a day-ahead plan of the unit is achieved. On the premise that whole control performances of a control area are guaranteed, smooth construction of the day-ahead plan of a generating unit is taken into account, and win-win of a unit plan, unit performances and area indicators is achieved.

Description

technical field [0001] The invention relates to the field of active power control of electric power systems, and relates to a closed-loop control method for power generation planning. Background technique [0002] With the increasing scale of the power grid and the continuous improvement of the automation level, as well as the introduction of the CPS evaluation mechanism, higher requirements are put forward for the dispatching operation and the function optimization of the EMS system. Under the premise of satisfying a good CPS index, how to give full play to the regulation performance of the unit, achieve the rational distribution of regional regulation needs among the units, and make the adjustment action of the unit reflect the characteristics of the power generation plan in real time, and realize the unit plan. The "win-win" of unit performance and regional indicators has become a problem that the current AGC (automatic generation control) system must solve. [0003] In ...

Problems solved by technology

In addition, the closed-loop control of power generation plan mentioned in the literature requires the unit to strictly follow the plan, which limits the adjustment ability of the unit to a certain extent. In order to ensure the overall control performance of the region, it is required to invest a large number of thermal power units to participate in the regulation.
