Abstract

The embodiment of the invention provides a cluster AGC load distribution method and system for realizing efficient and flexible regulation and control of regional coal power, and belongs to the field of power plant operation. The method comprises the following steps: judging whether each plant can participate in load regulation or not according to comparison of a dynamic output boundary of a unit cluster and an electric load instruction dispatched to the unit cluster; if the unit cluster electrical load instruction belongs to the current unit cluster dynamic output boundary, establishing a target model by taking a working mode in the unit cluster as the total coal consumption of all coal-fired power plants of an adjustable power supply, and solving the target model to obtain the optimal distribution load of each coal-fired power plant of the adjustable power supply in the working mode in the unit cluster, and formulating an optimal distribution scheme for the optimal distribution load of each coal-fired power plant of the adjustable power supply according to the working mode in the unit cluster. According to the method, the unit cluster electrical load instruction dispatched by the power grid is received by the regional coal power unit cluster AGC system, load optimization distribution is carried out among the power plants in the cluster, and then coordinated optimization operation among the power plants in the unit cluster is realized.

Description

technical field [0001] The invention relates to the field of power plant operation, in particular to a cluster AGC load distribution method for realizing efficient and flexible regulation of regional coal power and a cluster AGC load distribution system for realizing efficient and flexible regulation of regional coal power. Background technique [0002] The existing grid-connected units often use the single-unit AGC method to receive the remote control instructions of the grid dispatching EMS. The AGC direct-adjustment method of a single unit has the following problems: a) it cannot realize the economical distribution of the load of each unit within the power plant; b) it cannot be realized Optimal adjustment of the operation mode of the auxiliary units of each unit; c) AGC adjustment quality is often affected by the operating conditions and states of the main and auxiliary units of a single unit, so that the whole plant is subject to AGC assessment; d) It is easy to cause fr...
