Problems solved by technology

However, the current inter-provincial power dispatching only considers the power supply and demand situation and the power purchase price, and does not take into account the impact of inter-provincial power dispatching transactions on the province's resources and environment
Therefore, the current power dispatching control method is not easy to improve environmental protection benefits

Embodiment 1

[0032] refer to figure 1 , this embodiment provides a control method for inter-regional power scheduling, including:

[0033] Step S101, calculating the switching power value of the local area, and judging whether to purchase or send power according to the switching power value of the local area;

[0034] Step S102, if it is necessary to purchase electricity, obtain electricity price information and low-carbonization cost information in other regions, and calculate the actual electricity purchase cost value for purchasing electricity from other regions based on the electricity purchase price information and low-carbonization cost information ;

[0035] Step S103 compares the actual electricity purchase cost value with the value of local on-grid electricity, and determines the target area of ​​purchased electricity according to the comparison result;

[0036] Step S104, if it is necessary to send electricity outside, obtain local on-grid electricity price information and low-...

Embodiment 2

[0083] refer to figure 2 , this embodiment provides a control device for inter-regional power scheduling, including:

[0084] A judging module 201, configured to calculate the switching power value in the local area, and judge whether to purchase or send power according to the switching power value in the local area;

[0085] The first cost calculation module 202 is used to obtain power purchase price information and low-carbonization cost information in other regions when it is necessary to purchase electricity, and calculate power purchases from other regions according to the power purchase price information and low-carbonization cost information The actual power purchase cost value;

[0086] The first area determination module 203 is used to compare the actual cost value of electricity purchase with the value of local on-grid electricity, and determine the target area of ​​purchased electricity according to the comparison result;

[0087] The second cost calculation modu...

Embodiment 3

[0096] refer to image 3 , this embodiment provides a control system for inter-regional power dispatching, including:

[0097] The control device 301 for inter-regional power scheduling also includes a dispatch control system 302 and a first generating set 303 located in other areas, and a second generating set 304 located in this area.

[0098] For the specific structure and working principle of the control device, please refer to Embodiment 2, which will not be repeated here.

[0099] The control device 301 is connected to the second generator set 304 in the area, and is used to control the second generator set 303 to supply power to the target area of ​​external power transmission; in addition, the outsourced electricity request control signal generated by the control device 301 is sent to the outsourced electricity target The dispatch control system 302 of the area, the dispatch control system 302 is used to control the first generating set to supply power to the area.

Abstract

The invention provides an inter-area power dispatching control method, device and system. The method comprises the steps that the switching power value of the local area is calculated, and whether electricity needs to be purchased from other areas or not or whether electricity needs to be sold to other areas or not is judged according to the switching power value of the local area; if purchasing electricity from other areas is needed, electricity purchasing price information and low-carbon cost information of other areas are obtained, and the actual electricity purchasing cost value for purchasing electricity from other areas is calculated according to the electricity purchasing price information and low-carbon cost information; the actual electricity purchasing cost value is compared with the local grid purchase price value, and the target area from which the electricity is purchased is determined according to the comparison result; if selling electricity to other areas is needed, the local grid purchase price information and the local low-carbon cost information are obtained, and the actual electricity selling cost value for selling electricity to other areas is calculated according to the local grid purchase price information and the local low-carbon price information; the actual electricity selling cost value is compared with the actual electricity selling electricity price value, and the target area to which the electricity is sold is determined according to the comparison result. By means of the method, the benefit of environment protection can be improved.

Description

technical field [0001] The invention relates to the field of power dispatch control, in particular to a control method, control device and control system for inter-regional power dispatch. Background technique [0002] Electric energy has the characteristic that it cannot be stored on a large scale. The generation, supply, distribution, and consumption are completed instantaneously. In the power system, the power generation and load power consumption must be kept in balance at all times, so that the power grid can operate stably and the power quality can be guaranteed, namely: [0003] Generating power (MW) = load power (MW) (1) [0004] my country's power grid is divided by region. The power between provinces can be dispatched to each other. The provincial power grid dispatching center is responsible. The inter-provincial exchange power reflects the power exchange between the province and other provinces. This indicator will affect the safety of power grids in other provinc...
