Stair automatic generation control method under factory network coordination mode

Abstract

The invention relates to the field of planning and scheduling of a power grid and discloses a stair automatic generation control method under a factory network coordination mode which is capable of taking power grid safety and centralized control center control objectives into account, achieving organic link of on-line real-time control and an offline short-term scheduling plan and meeting the requirements of security, timeliness, practicality and economy of automatic gain control (AGC). The technical scheme includes: absorbing grid security constraints into the stair automatic generation control method, arranging planed power before the day of factory network coordination to be the centralized control center side AGC control objective, deciding power station load increase or load decrease input ordinal through monitoring deviation of power station integral power and planed power in real time, designing power plant combination method of load distribution between factories based on the power station load increase or load decrease input ordinal and conducting optimized load distribution between the factories using relative water consumption rate proportion. The stair automatic generation control method under the factory network coordination mode is capable of prospecting future development of power grids, and placing a significant leading role in the management of main current stair in china, in particular to giant main current stair schedule in the southwestern area.

Description

technical field [0001] The invention relates to the field of power grid planning and dispatching operation, in particular to a cascade automatic power generation control method in a plant-network coordination mode. technical background [0002] Automatic generation control (AGC) is an important technical means for the secondary regulation of power system frequency and an effective way to ensure the safe and high-quality operation of the power grid. In recent years, with the construction of UHV transmission projects, the degree of interconnection among regional power grids has been increasingly strengthened. The AGC control method for provincial and regional power grids has become a hot topic of research by scholars at home and abroad, and a large number of research results have been obtained. In the centralized dispatching mode, the AGC control objectives of the power grid mainly focus on maintaining the system frequency constant and inter-provincial connection line exchange...
