Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0041] Such as figure 1 As shown, a multi-period power generation plan coordination optimization and closed-loop control method includes the following steps:

[0042] Step 1: Prepare the monthly power generation plan; the monthly power generation plan can be divided into the beginning of the month and the month according to the start time of the plan. The monthly power generation plan aims at the minimum deviation of the power plant’s power schedule, and is based on the monthly system load forecast, monthly tie-line plan, and monthly bus load. Forecasting, monthly electrical maintenance and monthly power plant power plan, considering load balance constraints, unit operation constraints and grid...

Abstract

The invention discloses a multi-cycle generation scheduling coordinated optimization and closed-loop control method which comprises the following steps that first, a monthly generation schedule is made; second, a day-ahead generation schedule is made; third, an intra-day rolling schedule is made; fourth, AGC determines units which only bear basic power through unit classification, and the units which only bear basic power track the intra-day rolling schedule to achieve closed-loop control; fifth, actual operation data of the units are fed back to the monthly generation schedule, and the monthly generation schedule is corrected in a rolling mode. The multi-cycle generation scheduling coordinated optimization and closed-loop control method for the operation plan field is achieved, overall resource optimized allocation and safety constrained control on a longer time dimension are achieved, and the scheduling target for impartiality and openness plus energy conservation at the same time is achieved.

Description

technical field [0001] The invention relates to a multi-period power generation plan coordination optimization and closed-loop control method, which belongs to the field of power system dispatch plan. Background technique [0002] The operating characteristics of the power system determine that generation planning is a multi-cycle continuous rolling process, which requires continuous dynamic optimization of each cycle, including monthly planning, day-ahead planning, intraday planning, real-time planning and AGC control. In order to meet the requirements of lean scheduling and further implement the implementation of energy-saving power generation scheduling methods, it is necessary to conduct in-depth research on multi-period integrated power generation optimization scheduling technology to improve the safety, economy, energy saving and fairness of power generation planning. [0003] The core software for monthly, day-ahead, intraday and real-time power generation planning is...
