TECHNICAL FIELD
[0001] The present application relates to the field of heat supply, in particular to a heat network regulation system and method based on thermal energy storage. BACKGROUND
[0002] With the transformation of global energy structure towards clean and low-carbon, the proportion of renewable energy (such as photovoltaic and wind power) in the energy system continues to increase. For example, in China, under the "double carbon" goal, the annual growth rate of photovoltaic installed capacity is more than 20%, but its power generation has significant intermittency and volatility - when the light is sufficient during the day, the power generation is surplus, and at night or in rainy days, the supply is insufficient. This characteristic leads to the challenge of "source-load" imbalance for traditional power grid and heat network: when the photovoltaic power generation exceeds the electricity demand, the excess power needs to be consumed through heat storage, electric-to-thermal conversion, etc.; while in the peak of electricity demand or the low valley period at night, the stored thermal energy needs to be quickly released to meet the heat supply demand. Under this background, as the energy transmission carrier connecting the heat source and the user, the regulation system of the heat network needs to be upgraded to adapt to the fluctuation characteristics of renewable energy, to realize the efficient storage, flexible distribution and stable supply of thermal energy.
[0003] The traditional heat network regulation system mainly relies on the "on-demand production" mode of centralized heat sources (such as coal-fired boilers and gas heat and power cogeneration units), which matches the real-time load of users by adjusting the output power of heat sources. Although this mode can guarantee the stability of basic heat supply, it has obvious limitations when facing complex working conditions after the access of renewable energy: on the one hand, the response speed of traditional heat sources is slow (it takes several hours for a coal-fired boiler to start up to full load), which makes it difficult to quickly respond to the instantaneous fluctuations of photovoltaic power generation; on the other hand, there is a lack of effective thermal energy storage link, which leads to the inability to store excess thermal energy in time, and the only way out is to waste it by abandoning light or reducing heat source output, while at peak periods, due to insufficient storage, high-cost backup heat sources (such as gas boilers) have to be started, which not only increases the operating cost, but also violates the low-carbon goal. In addition, traditional regulation is mostly based on experience rules or simple feedback control, lacking the overall optimization ability of the whole network thermal energy distribution, user demand dynamics and renewable energy output, and is prone to problems such as local overheating or insufficient energy supply.
[0004] In recent years, breakthroughs in thermal energy storage technology have provided new ideas for solving the above problems. By storing excess heat energy in the form of sensible heat (such as hot water storage), latent heat (such as phase change material storage), or chemical energy, and releasing it when needed, the impact of renewable energy fluctuations on the heat network can be effectively mitigated. For example, high-temperature hot water storage tanks can store excess heat energy during peak photovoltaic power generation and provide continuous heating at night or on cloudy days; phase change heat storage materials further improve storage efficiency and response speed due to their high energy storage density and nearly isothermal charging and discharging characteristics. However, existing technologies have the problem of decentralized application - heat storage devices are often operated independently of the heat network control system, lacking a coordinated control mechanism with heat sources, pipe networks, and users, making it difficult to accurately match the stored heat energy to dynamic demand, restricting overall energy efficiency improvement. Based on this, the present application proposes a heat network regulation system and method based on thermal energy storage. SUMMARY

[0028] As Figures 1 to 3 the heat network regulation system based on thermal energy storage, comprising a temperature monitoring unit, an intelligent control unit, a thermal energy regulation unit, a warning module and a user terminal. The temperature monitoring unit is the core perception layer component and data source of the heat network regulation system. It uses temperature sensors to monitor the system globally, collects thermal energy regulation unit temperature and heat network temperature in real time, and uploads the collected data to the intelligent control unit.
[0029] The intelligent control unit is the data processing and analysis center of the heat network regulation system, and undertakes the whole process control functions of data integration, analysis and judgment, instruction issuance and system optimization.

[0031] The thermal energy regulation unit includes a heat extraction module, a heat exchange module, a thermal storage module and a heat compensation module. The gas inlet end of the heat extraction module is connected with the reheated steam pipeline near the intermediate stage of the heat network steam turbine or the burner. The gas outlet end of the heat extraction module is connected with the hot fluid passage inlet end of the heat exchange module. The cold fluid passage inlet end of the heat exchange module is connected with the cold water outlet end of the thermal energy storage module.

The heat extraction module is connected with the thermal energy storage module through the heat exchange module, forming a thermal energy storage channel.
[0032] In use, when the heat energy adjusting unit receives the heat energy storage instruction, the hot steam extraction module works to extract the excess steam in the heat network to heat the cold water in the heat storage module, so as to realize heat storage, and the air inlet end of the hot steam extraction module is provided with a steam extraction stop valve and a throttle valve, so that the hot steam extraction module can accurately control the steam extraction flow, accurately match the heat load demand, and ensure the stable operation of the heat network.

The heating module works to heat the residual heat network water, so that the temperature of the residual heat network water directly reaches the required temperature. The heated residual heat network water can be directly returned to the heat network after passing through the mixer.
[0035] In Embodiment 1 of the present application, the mixer is a cyclone mixer.

The electric ball valves at the ends of the pipelines can control the opening and closing of the pipelines, so as to facilitate the maintenance of the pipelines. The temperature of the fluid in the pipeline can be monitored in real time by using the temperature sensor; the pressure of the fluid in the pipeline can be monitored in real time by using the pressure sensor; the excess pressure in the pipeline can be discharged by using the pressure relief valve, so as to improve the safety of the application; the flow of the fluid in the pipeline can be monitored in real time by using the flow meter, the intelligent control unit collects the temperature, pressure and flow of the fluid in the pipeline and other multi-dimensional data in real time, relies on advanced data analysis algorithms to deeply mine and multi-parameter coupling analyze the data, dynamically evaluates the system running state, accurately identifies potential risks, and realizes the overall intelligent regulation and active protection of the safe operation of the heat supply system.

The pipeline is wrapped with a heat preservation pad, so as to improve the heat preservation performance of the pipeline.
[0040] As shown in Figure 2 , as shown in Figure 2 , it is a schematic view of the connection between the thermal energy regulation unit and the heat supply network. When the thermal energy regulation unit releases thermal energy, the electric ball valve is used to block the heat supply network water, so that the heat supply network water cannot directly flow from the heat source to the user side. The low-temperature heat supply network water needs to flow through the thermal energy release channel, and after heat exchange, it can flow to the user side.
