Embodiment 1
[0107] A power grid scheduling method that can interrupt loads to participate in backup, such as figure 1 As shown, this embodiment includes the following steps: A) Data preparation, obtaining the day-ahead load data, wind power and photovoltaic day-ahead forecast data, interruptible load data and power generation resource data in the system, and recording the interruptible load participating in the day-ahead scheduling backup as A Class B, record the interruptible load participating in intraday scheduling backup as Class B; B) Based on consumer psychology, establish a model for the response uncertainty of interruptible load; C) Establish a model for interruptible load participating in day-ahead scheduling, and use the optimization algorithm Obtain the participation of Class A interruptible loads in the day-ahead scheduling plan; D) Establish a model for interruptible loads to participate in intraday scheduling. In the intraday scheduling, use the optimization algorithm to obta...

The invention relates to the technical field of power grid dispatching, in particular to a power grid dispatching method with participation of interruptible loads in reservation. The power grid dispatching method comprises the following steps: A) acquiring day-ahead load data, wind power and photoelectric day-ahead prediction data, interruptible load data and system internal power generation resource data, marking the interruptible load participating in day-ahead dispatching reservation as a class A, and marking the interruptible load participating in intra-day dispatching reservation as a class B; B) building an interruptible load response uncertainty model; C) building a model for participation of the interruptible load in day-ahead dispatching, and using an optimization algorithm to obtain the participation of the class A of the interruptible load in a day-ahead dispatching plan; and D) building a model for participation of the interruptible load in intra-day dispatching, and in theintra-day dispatching, using the optimization algorithm by scrolling to obtain the participation of the class B of the interruptible load in an intra-day dispatching plan. The method has the substantial effect that the accuracy of building a day-ahead-intra-day model for calling the interruptible loads by a system is improved.
Description
technical field [0001] The invention relates to the technical field of power grid dispatching, in particular to a power grid dispatching method capable of interrupting load participation in backup. Background technique [0002] With the rolling development of smart grid and new energy, a large number of new energy sources are connected to the grid. However, the backup resources provided by the power generation side are very limited, and it is difficult to meet the growing requirements of new energy grid connection. A single consideration on the demand side has prompted a series of changes on the demand side, and puts forward an urgent need for the participation of resources on the demand side in scheduling. Interruptible load, as a kind of virtual reserve generation capacity resource and transmission capacity resource, has attracted more and more attention in terms of peak regulation and congestion reduction. In some foreign power markets, interruptible loads have been allo...
