Abstract: Power load management information systems have evolved from initial load control to comprehensive management systems encompassing load, electricity consumption, voltage, and power factor. Most municipal-level power supply departments in China have already established such systems, demonstrating their effectiveness, particularly in the face of recent power shortages. This paper, using the Changzhi power load management information system as an example, provides a concise analysis of the comprehensive benefits of load management systems for users, power generation, power supply, and society, hoping to stimulate further discussion on the application of power load management information systems. Keywords: Power load management information system, benefits. A review of the one-year trial operation of the Changzhi power load management information system reveals that it has provided substantial real-time data to various departments, such as metering management, production management, and planning management. It has been particularly effective in combating electricity theft and metering device errors, offering direct economic benefits and guidance. For instance, in cooperation with the marketing department, it helped recover and correct a total of 6.37 million kWh of electricity used by companies like Tianguang Electric Stone Plant, resulting in approximately 3 million yuan in recovered electricity fees and penalties. This demonstrates the direct effectiveness of the Changzhi load management system in electricity fee collection, investigating electricity theft, and addressing violations. The Changzhi Power Load Management Information System offers more than just direct economic benefits. It plays an irreplaceable role and generates significant benefits from four aspects: users, power generation, power supply, and society. The following analysis of its role and benefits, based on the application of the load management system, is provided: We know that effective control of electricity load can improve the load curve shape and balance electricity consumption. Balanced electricity consumption can improve the utilization rate and operational economy of power generation and supply equipment. In cases of severe power shortages and prominent supply-demand imbalances, load control can prevent large-scale power grid outages and avoid impacting social production and residential electricity consumption. However, current load control, through continuous functional expansion, has evolved into a broader and newer load management information system. Our company uses this type of system. This system involves many aspects, and from different perspectives, it may appear excellent, or it may reveal certain problems. Therefore, a multi-faceted and in-depth study of its advantages and disadvantages is necessary to draw conclusions from a holistic and comprehensive perspective. 1. Benefits to users (1) The system can notify users of power outage information and load usage in advance, so that users can understand the grid operation in advance, which is convenient for production arrangement and avoids economic losses caused by power outages and sudden power outages; (2) Time-of-use pricing can be controlled and implemented as needed, which benefits users; (3) Power outages can be avoided, and users can use more electricity. 2. Benefits to power generation (1) The system's control function can help solve peak shaving problems; (2) It is conducive to improving the economy and safety of power generation. For example, when there is an emergency in the power system and there is a shortage of power, the load control device can be used to urgently shed loads, which can prevent the system from collapsing, thus improving the safety and economy of the entire system. (3) Comparison of load control with other solutions Although load control can solve peak shaving problems more economically, the entire peak shaving task should be able to adjust at least 20% to 25% of the peak load. In order not to cause great inconvenience to users, load control can only assist in peak shaving. The peak shaving task should be shared by various methods. The correct understanding is that if load control is not developed, this part of the task will also require a high cost, so developing load control is economically reasonable. Of course, when the power grid is short of electricity, it is also necessary to reduce the peak load by 20% to 25% by load control. This situation further illustrates that load control is a good method that costs little money and can restore the power supply and consumption order quickly. (4) A stable load curve can generate more electricity. It goes without saying that a stable load curve can generate more electricity. At the same time, because the load is stable, it can create conditions for the use of nuclear power, because a stable load is an important condition for the safe and economical operation of nuclear power units. 3. Economic benefits of power supply (1) Reduce electricity purchase cost. Through the load reading and market analysis functions of the system, the accuracy of market forecasting is improved. The system's gate metering automatic meter reading and small power plant management functions provide support for the economic operation after the separation of power plants and grids. At the same time, load control can reduce the maximum demand of the power grid and increase the load factor. If our company calculates based on a grid supply load of 500,000 kilowatts, and reduces the peak demand by 5% every year, then the electricity purchase cost can be reduced by 1.8 million yuan per year. (2) Reduced line losses: Since line losses are proportional to the square of the load, controlling peak load and increasing the load factor will reduce the maximum load and thus reduce the losses of the power supply system. The cumulative reduction in line losses is considerable. (3) Increased power supply: Due to the reduction in peak load and the increase in load factor, the same capacity power supply equipment can supply more power, thus directly increasing the output value and profit of the power supply department. For example, in July this year, our company experienced a system failure, which caused the No. 1 main transformer of the Guoyi substation to be overloaded. Through this system, the user load was effectively controlled, which brought certain economic benefits to the company. (4) Automation of power quality and metering device monitoring: Automation of power quality and metering device management requires the establishment of a channel from the control center to the user. Since load management must first establish such a channel, the development of the load management information system can lay a certain foundation for the automation of power quality and metering device management. The remote meter reading function of load management can automatically read the information of the electricity meter in real time and monitor various electricity consumption information of users in real time, such as electricity consumption, load, voltage qualification rate, harmonic data, power factor, etc., providing information resources for marketing management and production management, and improving the automation level and work efficiency of power supply enterprises. (5) Provide technical means for the realization of penless marketing process. Marketing management needs to establish various customer information (market) collection and analysis systems. Since the load management information system establishes an organic connection between customers and the power system, it lays a solid foundation for marketing automation. 4. Social benefits (1). The data collection and storage function of the system provides data resources for power planning, construction and production operation. At the same time, after the implementation of load control, there is no need to cut off the power supply, avoiding the situation where residents and public lighting are also forced to be interrupted. Therefore, it is conducive to social stability and maintaining good order. (2). Establish a normal power supply and consumption order. Through the information service function of the terminal, it automatically, conveniently, quickly and economically provides customers with power production information, so that customers can arrange production power consumption in advance, which is conducive to the development of national economy and promotes social progress. In summary, the power load information management system reduces peak load and increases off-peak load, connects the information channels from power supply to users, and automates real-time data collection, storage, calculation, statistics, and analysis. This improves the economic efficiency and security of power generation, supply, and consumption, allows for the tapping of the potential of power generation, supply, and consumption equipment, and can delay construction investment. It serves as an example of achieving significant revenue with minimal investment in urban power grid transformation and is a typical example of developing production through intrinsic motivation. In conclusion, the application and construction of the Changzhi power load management information system has significant economic and social benefits.
