Provincially-locally integrated load batch cooperative control method and system

Abstract

The invention relates to a provincially-locally integrated load batch cooperative control method and a system. Based on a provincial-local intelligent power grid regulation and control isomorphic system, in case of an emergent accident, load that each region should provided is calculated through provincial regulation; a load cutting target value is issued to each region; the local regulation receives a control command to shake hands for three times with the provincial regulation; and load batch cutting is performed according to the load cutting target value. Thus, provincial regulation one-button type batch load control is achieved; in the case that when large power is deficient in the provincial power grid, rapid and batch control of load of each region is achieved; and safe and reliable operation of regional power grid is effectively ensured. According to the invention, by use of a cross system service bus, cooperative interaction of provincial-local load batch control information, rapid issuing of the control command and real-time feedback of the control result are achieved; safety and rapidness of batch load control between provinces and regions can be greatly improved; and safe and stable operation of the power grid in case of an emergency is ensured.

Description

technical field [0001] The invention belongs to the technical field of electric power system dispatching automation, and relates to a load batch cooperative control method and system integrated in a land-saving manner. Background technique [0002] In the case of a major accident in the regional power grid resulting in a large power shortage, the provincial dispatch side needs to remove a large number of loads from the whole province to ensure the safe operation of the power grid. Since the dispatching automation system of the provincial dispatching smart grid does not have problems such as modeling of low-voltage equipment and control authority, it is not possible to directly complete the load removal of each region through the provincial dispatching system when performing load shedding, and it is necessary to complete the corresponding regional load quickly through the local dispatching system. resection. In order to deepen the work requirements of provincial-regional int...

AI Technical Summary

Problems solved by technology

[0004] 1. Low degree of automation and lack of unified management

The provincial commissioner issued control instructions to each local dispatcher, mainly manual operation, lacking unified process management

Moreover, the load control status and control result statistics cannot be sent to the provincial dispatcher in real time, and the provincial dispatcher cannot make the next decision based on the control situation

[0005] 2. There is little interaction between provinces and places, and the security is low

There is a single way of information interaction between provinces and regions, mainly through telephone and other means of communication. For control instructions and execution instructions, provincial-level dispatch centers cannot achieve accurate verification with prefecture-level dispatch centers, and the security is greatly reduced

[0006] 3. Low control efficiency

The traditional model lacks effective closed-loop measures, with high manual dependence, slow issuance of control instructions, and low load control efficiency. Provincial-level control centers need to manually communicate with multiple prefecture-level control centers to confirm control instructions one by one, and prefecture-level control centers may fail. Respond to the needs of provincial dispatching centers in a timely manner, affecting the safe and stable operation of the power grid
