Description

Technical Field

[0001] The present invention relates to the field of power system intelligent technology, and in particular to a system protection intelligent analysis system and method based on a load aggregation management platform. Background Art

[0002] To ensure the safety of the large power grid during the transition period, State Grid Corporation of China built a comprehensive defense system for the safety of the large power grid, namely "system protection" in 2016. For example, the frequency emergency coordination and control system (Phase I) of the East China Power Grid was officially put into operation on July 5, 2016. Among them, taking the large-scale source-grid-load friendly interactive system organized and carried out by Jiangsu Company as an example, the millisecond-level precise load shedding project implements the first time limit control for the frequency emergency control requirements, and quickly cuts off some interruptible loads within 650 milliseconds. The millisecond-level precise load shedding system realizes the precise real-time control of the interruptible load, and has become an important pillar for building a comprehensive defense system for the safety of the large power grid. In addition to providing frequency emergency control with low-cycle load shedding according to frequency, it can also quickly and accurately control new resources. The results of drills, field tests and actual fault handling all show that the millisecond-level precise load shedding system of Jiangsu Power Grid can effectively shorten the response time of UHV DC fault handling, improve the efficiency of accident handling, ensure the safe operation of the large power grid, and minimize the impact of power grid failures on users and society.

[0003] However, while the system protection has achieved great success, the inventor has found through research that the current construction of system protection focuses on the system protection device at the plant and station end. As the initiator and decision-making end of the actual dispatching control instructions, the function of the dispatching end of the system protection is still relatively weak. Taking Jiangsu as an example, the Jiangsu precise load shedding system, as part of the East China system protection, has realized the access and centralized monitoring of the precise load shedding control device at the dispatching center station, and deployed the precise load shedding device communication module, the precise load shedding device information centralized monitoring, the precise load shedding device and the system operation status online identification module and other functions, realizing the unified monitoring and management of the precise load shedding control device. However, with the further development of the UHV AC and DC power grid and the rapid increase in inter-provincial exchange power, it is urgent to carry out the intelligent analysis of the whole process of system protection action behavior on the basis of monitoring and analyzing the system protection device body, and enhance the application depth of system protection. At present, there is no system protection intelligent analysis system based on the load aggregation management platform to provide dispatching and operating personnel with the overall operation status monitoring and analysis of system protection and the evaluation of action effect, as well as an intelligent analysis system for analyzing and inverting the whole process of the accident after the actual action of the system protection.

[0004] Therefore, how to provide a system protection intelligent analysis system based on the load aggregation management platform to give full play to the function of system protection, improve the practicality and intelligence level of system protection, and thus improve the analysis ability of dispatching and operating personnel has become a technical problem that technicians in this field need to solve urgently.

[0039] <Example 1>

[0040] This embodiment provides a system protection intelligent analysis system based on a load aggregation management platform. The source-grid-load-storage control module of the load aggregation management platform includes a marketing load control interface module and a load regulation module. Figure 1 The system protection intelligent analysis system provided in this embodiment includes a load aggregation layer 100, the marketing load control interface module 200 and the load regulation module 300. The load aggregation layer 100 is interconnected with the marketing load control master station 400 through the marketing load control interface module 200; the load aggregation layer 100 is configured to classify and aggregate the electrical equipment according to the user's electricity consumption behavior characteristics to obtain classified loads. The marketing load control interface module 200 is configured to obtain the load response information of the classified load and report the load response information to the load regulation module 300. The load regulation module 300 is configured to perform load forecasting, load aggregation, classification statistics, capacity decomposition of load response, monitoring of response execution time events and post-evaluation response according to the load response information; and is used to formulate load control plans based on the real-time power data of the electrical equipment collected by the user-side terminal and the load response information of the classified load.

[0041] Specifically, the load aggregation layer 100 is configured to analyze the characteristics of user power consumption behavior, determine the classification of typical power equipment (loads), and use methods such as parameter identification aggregation and Monte Carlo simulation aggregation to model the load aggregation of similar power equipment and different power equipment, and model the internal operation characteristics of the scaled load. In this way, the power equipment is aggregated and controlled by user and region.

[0042] Preferably, as attached Figure 2 As shown, the classified loads include industrial users, commercial users, residential users, aggregators, energy stations and / or integrated energy service providers; the electrical equipment includes electric vehicles, non-industrial air conditioning systems, smart lighting, cold and heat storage equipment, smart building distribution substations and / or smart homes. Obviously, Figure 2The classified loads shown in are only descriptions of preferred implementations, and are not limitations of the present invention. In other implementations, the electrical equipment may also be classified according to other electrical characteristics, such as trend loads, periodic loads, and random loads; the electrical equipment may also be classified according to various electrical scenarios as plannable, controllable, monitorable, and detectable, and the present invention does not limit this. As can be seen from the figure, based on the classified loads of the load aggregation layer 100, the marketing load control interface module 200 is used to obtain the load response information of the classified loads. With such a configuration, a large number of electrical equipment with similar start-up time, duration, and control method and small individual capacity can be integrated into one or more large-capacity, controllable classified loads (load logic aggregates), thereby improving the reliability of system operation and adapting to various scenarios such as peak load regulation and frequency regulation. Moreover, compared with increasing installed capacity, it is low-cost and easy to implement.

[0043] Preferably, in one of the exemplary embodiments, the load control plan includes load control strategies for different priority targets, and the load control strategy is obtained according to the area where the load is located, the load response characteristics, and the load time characteristics being controlled. For example, controllable capacity aggregation is carried out for power equipment by type, user, and region, and load control plans are compiled according to different target requirements of municipal dispatch. With such a configuration, on the basis of the existing technology of precise load shedding, the load control plan fully considers the requirements of the area where the load is located, the load response characteristics, and the load time characteristics being controlled, so that through in-depth mining and analysis of the system protection strategy, the action behavior of the system protection device, and the action effect, the dispatching and operating personnel can grasp the system protection action behavior and control effect, thereby improving the level of system protection intelligence and the analysis ability of the dispatching and operating personnel.

[0044] Preferably, see Appendix Figure 3 , the load response information includes load installed capacity, real-time operating load data, load adjustable capacity and / or load response data. Specifically, the load installed capacity includes classified load reporting capacity, classified load internal energy efficiency component reporting capacity and total load reporting capacity; the real-time operating load data includes the current operating classified load capacity, total load capacity, current load baseline, total load forecast, classified load forecast, classified load response capacity; the load response data includes total adjustable load, classified load adjustable amount, confirmed total load response amount and load subsidy. So configured, the marketing load control interface module 200 provides a secure access area for the load aggregation layer 100 and the marketing load control master station 400. Preferably, the load aggregation layer has a universal interface and data, and further communicates with the marketing load control master station 400 through vertical encryption. Preferably, the data exchange between the load aggregation layer and the marketing load control master station can be achieved through relevant standards.

[0045] With such configuration, according to the load control plan provided by the load regulation module 300, during actual scheduling, the dispatching operator selectively performs load control based on the existing management load situation, the load regulation module 300 receives the load response information from the marketing load control master station 400, the user-side terminal collects the real-time power of the user equipment and formulates the load control mode of the equipment, and after the user-side terminal receives the load capacity control instruction of the load aggregation layer 100, it provides a fault protection function that may be caused by load control based on the control plan of different energy-consuming components in the electrical equipment.

[0046] See attached Figure 4 , a system protection intelligent analysis system based on a load aggregation management platform provided by one of the embodiments of the present invention, the load control module carries out internal load forecasting, load aggregation and classification statistics, load response capacity decomposition scheme, response execution event monitoring and post-evaluation response evaluation. The marketing load control interface module (load aggregator platform interface) reports the installed capacity, adjustable load data, execution capacity data, and master station model interaction data. The load control plan fully considers the area where the load is located, the load response characteristics, time characteristics, controllable capacity size, and the requirements for the load to be controlled, and formulates load control strategies for different priority targets. With such configuration, taking the monitoring and analysis module, which is an important component of the intelligent and safe operation of the power grid, as an example, the system protection intelligent analysis system based on the load aggregation management platform provided by the present invention can provide the monitoring and analysis module with load forecasting, classification statistics, response execution event monitoring, post-evaluation response evaluation and / or load control strategy, and the monitoring and analysis module can realize real-time peak-shaving statistics, peak-shaving effect analysis, customer energy analysis, customer response analysis and / or power loss statistics.

[0047] See the attached Figure 4 In one embodiment, it can be understood by those skilled in the art that, preferably, the system management module, the support platform and the acquisition and control module are important components of the load aggregation management platform, and their functions include but are not limited to the following situations, wherein the functions of the system management module include equipment management, building management, terminal management, interface management, contract management and meter management; the functions of the support platform module include implementation data services, historical data storage, basic information maintenance, graphic configuration, report services, chart analysis, alarm services and authority management; the functions of the acquisition and control module include energy consumption data collection, environmental parameter collection, equipment status collection, equipment operation control and data quality management. Due to space limitations, they will not be elaborated one by one.

[0048] Preferably, the access methods of the classified loads include direct access and access through the load aggregation management platform. Among them, the direct access includes accessing the control substation or the marketing load control main station through 4G and / or fiber private network. It can be understood that the control substation includes but is not limited to millisecond-level control substations. The access through the load aggregation management platform includes accessing the marketing load control main station through the marketing load control interface module (secure access area), and the load aggregation management platform selectively responds to the demand released by the load scheduling. As an exemplary embodiment, the resources for direct access to the millisecond-level control substation or marketing load control are mainly through 4G or fiber private network.

[0049] Preferably, in one exemplary embodiment, the load aggregation layer includes a vehicle networking platform aggregator and a common aggregator that is not included in the vehicle networking platform aggregator. Figure 5 , which is a schematic diagram of a system intelligent analysis system based on a load aggregation management platform provided by the present invention to realize orderly charging of electric vehicles to access the aggregation layer. In this embodiment, the Internet of Vehicles platform aggregator includes commercial fast charging, and the commercial fast charging pile directly interacts with the load aggregation layer through Ethernet or 4G public network. The orderly charging control charging piles of residents that are not included in the Internet of Vehicles platform aggregation are connected to the energy router through Ethernet / 485, and the energy router is connected to the energy controller through PLC. The energy controller realizes information interaction with the load aggregation layer through fiber-optic private network / GPRS / fiber-optic Ethernet and other methods. The general process of realizing orderly charging of residential electric vehicles is as follows: according to the pre-set vehicle use time, charging is started, and the strategy formulated by the load control module of the load aggregation management platform (marketing load control master station) is sent to the energy router. Before the vehicle use time arrives, the energy router can start charging, suspend charging, and continue charging through the AC pile according to the strategy requirements, thereby realizing orderly charging.

[0050] It can be seen that the system intelligent analysis system based on the load aggregation management platform provided by the present invention, with the help of the powerful global information acquisition capability, multi-source data collaborative analysis capability, and rich information display means of the dispatching end, the dispatching end function of the system protection plays a powerful role. Through the comprehensive analysis, evaluation and decision-making of the quantity measurement, state quantity and other information sent by the plant and station devices, the overall operating status and action effect of the system protection are provided to the dispatching operation personnel, and the adaptive analysis and optimization decision of the system protection strategy are further carried out in combination with the power grid operation mode data. After the actual action of the system protection, the whole process of the accident is analyzed and inverted, so as to give full play to the function of the system protection and improve the practicality of the system protection.

[0051] Furthermore, the present invention provides a system intelligent analysis system based on a load aggregation management platform, which is based on the dispatching end of system protection. The load aggregation layer, the marketing load control interface module and the compliance regulation module work closely together. Through in-depth mining and analysis of system protection strategies, system protection device action behaviors and action effects, it is possible to perform real-time analysis of system protection action behaviors and control effects, thereby improving the level of system protection intelligence and further improving the analysis capabilities of dispatching and operating personnel.
