Embodiment Construction
[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0059] This embodiment discloses a method for setting a demand control limit value, which is applied to a scenario where demand control is required, and can determine whether demand control is required after acquiring real-time power history data on the load side. Specifically, When the real-time power history data meets all of the following conditions, it is determined that demand control is required:
[0060] The type of power consumption is large industrial...

The invention provides a setting method and device of a demand control limit value. After real-time power historical data of a load side is acquired, an energy storage capacity value and an energy storage power value are calculated according to the real-time power historical data within a calculation period and an initial value and increment of a target demand value which is preset with regard toeach calculation period within a preset time frame, a plurality of energy storage capacity values and a plurality of energy storage power values in the calculation period are obtained with constant increasing of the increment, on the basis, the optimal energy storage capacity value and the optimal energy storage power value in the calculation period can be accurately calculated by maximum user-side benefit as an optimization target, the optimal energy storage capacity value and the optimal energy storage power value in each calculation period within the preset time frame are similarly obtained, the optimal energy storage capacity value and the optimal energy storage power value with the preset time frame are determined, and finally, the optimal demand control limit value is accurately calculated by considering a demand control margin coefficient and the optimal energy storage power value within the preset time frame.
Description
technical field [0001] The present invention relates to the technical field of electric power control, and more specifically, to a method and device for setting demand control limit values. Background technique [0002] In the demand control system, in order to configure the charging and discharging power and energy storage capacity of the energy storage system, it is necessary to set a demand control limit for the target load. The choice of demand control limit is related to the size of energy storage capacity, charging and discharging power, related to the size of the system cost, and also affects the success or failure of the energy storage scheme. [0003] At present, engineers mostly rely on experience to set demand control limits for enterprises by observing historical data of enterprises' electricity consumption, forecast data of electricity consumption, and electricity price parameters. However, the demand control limit set in this way cannot obtain the optimal valu...
