Optimize the efficient, safe and collaborative use of demand-side resources, and promote the comprehensive upgrade and innovation of demand-side management



Why strengthen power demand side management

1. Stimulate the potential of demand-side resource regulation and enhance the flexibility of the power system

Under the requirements of new power system construction, it has become the main task of power management to play the role of power demand side management and enhance the power security guarantee ability. On the one hand, there is a wide range of demand response subjects, including all kinds of operational power users, non-operational power users and comprehensive energy users. By expanding the scope of participants, the potential of demand-side resources can be better mobilized and the flexibility of the electricity market can be improved. On the other hand, economic incentives and other means can stimulate the flexibility of demand-side resources, guide power users to independently optimize and adjust the power load, and meet the needs of stable operation of the power system. For example, in the form of price incentives, offer offers to adjustable and controllable resources, and encourage users to reduce electricity consumption when the power supply is tight, so as to ensure the flexibility of the power system.

2. Strengthen the bottom line thinking of power safety to ensure the balance between supply and demand of the power system

With the continuous increase of electricity load, especially in the peak time of high temperature in summer and cold wave in winter, the power demand shows an obvious peak, which seriously threatens the safety and stability of the power grid. Therefore, in order to ensure the stability of electricity consumption, it is necessary to strengthen the thinking of power safety, take power safety as the primary goal, strengthen the cognition and response ability of power system risks, and ensure the stability and reliability of power supply. At the same time, it is urgent to improve the supply and demand balance capacity of the power system by strengthening the standardization of power load management and the rationality of power demand side management, such as guiding residential users to take energy-saving measures during peak hours, effectively reducing the load pressure of the power system, reducing the overall operation risk of the system, and providing sustainable and high-quality power services.

3. Expand the new pattern of electric energy substitution, and realize the synergistic effect of energy conservation, emission reduction and carbon reduction

Based on the current situation of power supply and demand, with market demand as the guide, the implementation of electricity instead of coal, electricity instead of oil and other measures in the terminal energy consumption link, expand the scope and depth of electric energy replacement, more energy consumption to green energy, reduce the dependence on coal and oil and other traditional energy, so as to reduce the negative impact on the environment, in response to the national call for energy conservation and emission reduction. At the same time, through the alternative way of electric energy, promote the synergy between supply and demand of green electricity, reduce energy consumption and carbon emissions, improve energy efficiency, and achieve a win-win situation of economic and environmental benefits, which not only meets the national goals and requirements of energy conservation and emission reduction, but also provides a feasible path for sustainable development.

Strengthening the core requirements of power demand side management

1. Optimize demand response mechanism -- Ensure efficient operation of market demand response

In order to accelerate the synergy between source and network load and storage, and comprehensively promote the participation of demand-side resources in the normal operation of the power market, the two methods have defined "demand response" again, and clearly pointed out that "demand response" will be one of the important ways of peak cutting and valley filling, grid regulation and power supply protection. And put forward to establish and improve the demand response price mechanism connected with the electricity market. According to the principle of "who benefits, who bears", unify and standardize the rights and responsibilities of the main body responsible for power load management, support areas with conditions, and improve the level of economic incentives through the implementation of peak electricity prices and other means. Demand response entities are encouraged to participate in the corresponding electricity and energy market, auxiliary service market, capacity market, etc., and obtain economic benefits according to market rules.

In addition, the "Power load Management Measures (2023 version)" emphasizes stimulating the flexibility of demand-side resources, guiding users to optimize and adjust the power load independently, and improving the consumption and utilization level of renewable energy; The Measures for Power Demand Side Management (2023 version) emphasizes the establishment and improvement of the connection mechanism between demand-side resources and power operation regulation, and gradually integrates demand-side resources into the power supply and demand balance system by means of virtual power plants, so as to improve the flexibility of the power system.

2. Improve the standard of orderly electricity consumption - emphasize the bottom line of ensuring the supply of electricity to ensure the people's livelihood and key users

In order to meet the balance of supply and demand and ensure the increasing requirements of all parties in society for the safe and stable supply of electricity, it is necessary to continuously improve the orderly electricity consumption standards to ensure the safe and stable operation of electricity and ensure the people's livelihood. The "Power Load Management Measures (2023 version)" further scientifically standardized and orderly the whole process of electricity consumption from the implementation level, and pointed out that the balance of power consumption is arranged in the order of first wrong peak, then peak avoidance, and then power limiting. Compared with the "Measures for Power Demand Side Management (2023 version)", the "Measures for Power Load Management (2023 version)" more strictly regulates the adoption of orderly electricity consumption measures, and proposes that orderly electricity consumption shall not be implemented in the name of national and local energy conservation target responsibility evaluation and assessment for energy-using enterprises and units.

3. Strengthen system support construction -- promote the upgrade and application of power load management system

In order to assist the information technology of power demand side management and ensure the smooth implementation of load management, a new power load management system is proposed for load information collection, forecast analysis, testing, regulation and service for power users, load aggregators and virtual power plants. The power load management system can improve the ability of accurate load measurement, monitoring and forecasting. Through the introduction of advanced monitoring equipment and data analysis technology, the system can obtain real-time load information and accurately predict load changes. Such capability enhancement will contribute to more refined and flexible load scheduling to meet market demand and ensure the stability of power supply.

In general, the implementation of power load management is a key link to ensure that the power supply is strong, orderly and effective, and has played an important role in easing the power supply shortage and power supply, and will continue to play a more important role in the future, which will better ensure the smooth and orderly operation of the national power.

The way forward for power demand side management

1. From the perspective of working mechanism, broaden the scope of demand response subject and realize multi-level coordination of demand side resources

In the traditional power system, demand response participants and resource exploitation are insufficient, resulting in insufficient resource utilization and unable to achieve the optimal synergistic effect. Therefore, it is necessary to broaden the scope of demand response subject and promote multi-level coordination of demand side resources. We can continue to deepen the establishment of a comprehensive platform, through the establishment of a unified comprehensive platform, integration of various demand response entities, centralized management and scheduling of resources, and improve synergies. In addition, it is necessary to promote the large-scale development of the already mentioned demand response resource base. Because there are a large number of decentralized, lightweight, personalized resources on the demand side, there are uncertainty factors such as individual obstacles, time limits, and power changes, the difficulty of accurate regulation is higher than that on the power supply side. The large-scale grid-connection of uncertain source load resources will have an impact on the regulation method and operation characteristics of the power grid, and will also increase the difficulty of short-term accurate quantification and balanced control of new energy output and load response. Expanding the construction of demand response resource base can enhance the efficient interaction between supply and demand, and fully regulate the participation of demand-side resources in power operation.

2. From the market, give full play to the regulation role of the demand-side resource market to realize the normal operation of the power market

Giving full play to the regulation role of the demand-side resource market is the key to realize the normal operation of the power market. This regulatory role helps to improve the reliability, stability and economy of the power market, promote the sustainable development of the power market, and adapt to the needs of energy transformation and power system reform. Therefore, the in-depth study and effective implementation of the demand-side resource market regulation mechanism has important academic and practical value for the normal operation of the power market. Sound market rules and mechanisms can be formulated, including market access, trading mechanisms, charging mechanisms, etc., to ensure fair competition and effective operation of the electricity market. At the same time, the establishment of a sound market supervision mechanism, strengthen the supervision of market participants, in order to promote the normal operation of the market. In addition, it is also necessary to continue to promote the diversification of demand-side resources and encourage and support different types of demand-side resources to participate in the market, including industrial and commercial users, residential users and distributed energy. Through the participation of diversified demand-side resources, the balance of supply and demand and the optimal allocation of resources in the electricity market can be achieved, and the flexibility and efficiency of the market can be improved.

3. Technologically, promote the innovation and application of a new generation of demand-side management technology to achieve large-scale adjustment technical support

Power demand side management combined with demand response, power substitution, power saving, green power, smart power and other fields of technology, can achieve intelligent power consumption and power utilization efficiency. According to the supply and demand of the power system, the power consumption behavior and time of the user can be adjusted to adapt to the load change of the power system through the demand response technology. Electric energy replacement technology can reduce dependence on traditional energy and reduce carbon emissions by promoting electric power to replace traditional energy. Energy-saving technologies focus on optimizing energy use and reducing energy waste, such as the use of energy-efficient equipment and energy management systems. Green electricity emphasizes the use of electricity generated by clean energy to reduce the negative impact on the environment. Smart electricity technology through smart meters, smart home equipment, etc., to achieve intelligent management and control of power consumption, improve power efficiency and reduce energy waste. At the same time, the use of new energy storage technology, virtual power plants, vehicle network interaction, micro-grid and other innovative applications can achieve flexible scheduling of electricity and effective storage and utilization of energy.

In addition, with the help of a new generation of information technology means, such as "cloud computing, big data, Internet of Things, mobile communication and artificial intelligence", intelligent management and monitoring of power consumption can be realized, accurate energy data and prediction models can be provided, and technical support can be provided for the large-scale regulation of the power system.

Through the power load management, integrate the demand response resources on the load side, accelerate the construction of a new power load management system, and lay the foundation for better promoting the power load access system and invocation. Through the application of power demand side management combined with various technical means, the intelligent power consumption can be realized, the efficiency of power utilization can be improved, and the mode of power utilization can be innovated, so as to provide support for the sustainable development and large-scale adjustment of the power system.
