[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.
[0003] As a clean, efficient and stable green energy, nuclear power generation can effectively replace and reduce coal consumption, optimize the energy structure, and slow down the long-term growth rate of carbon dioxide emissions. With the construction of new power systems, the country's new energy installed capacity has grown rapidly. The characteristics of renewable energy such as large intermittency and large fluctuations have led to increased peak-shaving pressure. As a direct-shaving unit close to thermal power units, nuclear power units are imperative to participate in peak-shaving, but nuclear power peak-shaving will inevitably increase the operating cost of nuclear power plants. The comprehensive utilization of nuclear power in conventional power supply, clean heating, industrial heating, seawater desalination, and comprehensive utilization will inevitably be fully upgraded. The nuclear power peak-shaving system can achieve resource sharing and optimal configuration, improve utilization efficiency, and reduce the investment cost and operating cost per unit power. In the current nuclear power peak-shaving technology, the utilization of waste heat mainly depends on energy storage systems and seawater desalination systems. The energy storage system includes electricity storage and heat storage. However, the two systems have significant differences in waste heat utilization efficiency and storage and release capacity, and lack an effective general evaluation method.

[0042] Embodiment 1
[0043] Embodiment 1 of the present invention introduces an energy storage and release evaluation method for a nuclear power peak regulation system.
[0044] like Figure 1 An energy storage and release evaluation method for a nuclear power peak regulation system is shown, comprising:
[0045] Obtain the influencing factors of nuclear power peak load regulation system;
[0046] Analyze the influencing factors obtained, determine the key energy storage and release indicators of the nuclear power peak-shaving system, and build an energy storage and release evaluation indicator system;
[0047] According to the constructed energy storage and release evaluation index system, the storage efficiency index of the nuclear power peak regulation system is calculated;
[0048] The energy storage-release comparison coefficient is calculated based on the obtained storage efficiency index to complete the energy storage-release evaluation of the nuclear power peak-shaving system.
[0049] In this embodiment, the determined key index analysis for storage and release evaluation includes waste heat source analysis, energy storage system characteristic analysis, seawater desalination process analysis, and power grid load demand analysis.
[0050] In the process of waste heat source analysis, the waste heat characteristics generated by the nuclear power system are understood to determine its adaptability to energy storage and seawater desalination processes, including:
[0051] (1) Heat level (temperature range): high-temperature waste heat can be used for heat storage systems or steam turbine power generation. Medium- and low-temperature waste heat is suitable for driving seawater desalination processes or low-temperature heat storage systems;
[0052] (2) Heat flow rate, ensuring the stability of waste heat supply and avoiding efficiency reduction due to waste heat fluctuations;
[0053] (3) Waste heat utilization efficiency, which measures the ratio of input heat energy to actual heat energy utilized, affects the overall system performance.
[0054] In the process of analyzing the characteristics of the energy storage system, the technical characteristics of the energy storage system are clarified, and the key indicators that are compatible with nuclear power peak regulation are extracted, including:
[0055] (1) Storage efficiency: The efficiency with which the energy storage system stores and releases input energy is a core technical performance indicator;
[0056] (2) storage time, which measures the system's ability to adapt to different load demands of the grid (short-term rapid response or long-term energy release);
[0057] (3) Response speed: The response time of the energy storage system to provide support when the load fluctuates, which affects the flexibility of the system;
[0058] (4) Storage capacity: The total capacity of the energy storage system determines its ability to absorb waste heat;
[0059] (5) Operation stability: the output stability of the energy storage system under different operating conditions.
[0060] In the process of seawater desalination process analysis, the adaptability and utilization efficiency of seawater desalination process to nuclear power waste heat are evaluated, including:
[0061] (1) Unit water production efficiency, which refers to the amount of fresh water that can be converted per unit of input heat, is an important indicator for measuring seawater desalination technology;
[0062] (2) Process heat source requirements, the temperature and flow requirements of waste heat for seawater desalination, and the matching degree with the waste heat provided by nuclear power plants;
[0063] (3) freshwater storage capacity, which measures the total amount of freshwater that the system can store to cope with fluctuations in demand;
[0064] (4) Water production stability: the stability of fresh water output during long-term operation of seawater desalination equipment.
[0065] In the process of grid load demand analysis, the operational adaptability of the energy storage system or seawater desalination is determined according to the grid load characteristics, including:
[0066] (1) Load fluctuation amplitude, which reflects the difference between the maximum and minimum demand of the power grid load and determines the peak load demand;
[0067] (2) Load response time, the time required for the energy storage system or desalination process to respond to changes in grid load;
[0068] (3) Long-term load demand and the grid’s energy absorption capacity during low periods affect the continuous operation of the desalination process.
[0069] The key storage indicators in this embodiment include waste heat utilization efficiency indicators, storage capacity indicators and system stability indicators; specifically,
[0070] The waste heat utilization efficiency index includes the storage efficiency of the energy storage system and the fresh water production efficiency of the seawater desalination system, which directly measures the utilization rate of resources;
[0071] The waste heat utilization efficiency of the energy storage system is Among them, Q out is the energy input to the energy storage system, Q in The effective energy released;
[0072] Waste heat utilization of seawater desalination system Among them, W 产水量 is the amount of fresh water produced per unit time, Q in The effective heat released.
[0073] The storage capacity indicators include the storage time and storage response flexibility of the energy storage system, and the fresh water storage capacity of the seawater desalination system;
[0074] The storage time of the energy storage system measures the time the energy storage system can maintain power and is suitable for short-term and long-term load changes in peak demand, i.e. SD 储能 = Maximum sustainable power supply time (h);
[0075] The storage response flexibility considers the response speed of the energy storage system to the peak demand, that is, RF 储能 =Response time (s);
[0076] The freshwater storage capacity of a desalination system measures the total amount of freshwater that can be stored in the desalination system, i.e. WSC 淡化 = water storage tank capacity;
[0077] The system stability indicators in this embodiment include waste heat input stability, energy storage system energy output stability and seawater desalination system water production stability;
[0078] The residual heat input stability is in, is the standard deviation of the waste heat input, is the average value of the waste heat input;
[0079] The energy output stability of the energy storage system is Among them, is the standard deviation of the waste heat input, is the average value of the waste heat input;
[0080] The water production stability of the seawater desalination system is in, is the standard deviation of water production, is the average water production;
[0081] The storage efficiency index system in this embodiment is composed of waste heat utilization efficiency index, storage capacity index and system stability index; specifically,
[0082] The storage efficiency index of the energy storage system is
[0083] The storage efficiency index of the seawater desalination system is SE 淡化 =η 淡化 ×WSC 淡化 ×S 产水稳定性 ;
[0084] It is convenient to directly compare the storage capacity of energy storage system and desalination system, establish storage capacity comparison coefficient, and compare the storage efficiency of the two in a standardized way, that is,
[0085] If SCCR>1: it means that the energy storage system is more effective in storing nuclear waste heat;
[0086] If SCCR<1: it means the desalination system has a stronger storage capacity;
[0087] If SCCR=1: it means the storage efficiency of the two is equivalent.
[0088] like Figure 2 The seawater desalination system shown in the figure uses the waste heat in the nuclear power peak regulation as the driving heat source, and realizes the production and storage of fresh water through a specific process. The medium and low temperature waste heat generated by the nuclear power system is transferred to the seawater desalination system through a heat exchanger (i.e., steam generator 3 or low-pressure heater 9); the waste heat of the nuclear power plant is introduced into the seawater desalination device to heat the seawater to a suitable temperature; the seawater is separated into fresh water and concentrated brine through a distillation process. The produced fresh water is stored in a fresh water storage tank to cope with demand fluctuations. The operating parameters of the desalination device are adjusted according to the grid load and water demand, and the water production rate is controlled by adjusting the heat source input flow.
[0089] like Figure 3 The energy storage system shown in the figure uses the waste heat or power generation capacity of the nuclear power plant to store energy for grid load regulation. The waste heat heats the heat storage medium through the heat exchanger, and the heat energy is stored in the high heat capacity medium and kept at a high temperature for subsequent use. The heat energy in the heat storage medium is released through the heat exchanger to drive the steam turbine to generate electricity; during the off-peak power generation period of the nuclear power plant, part of the electricity is input into the energy storage device. The electrical energy is stored through batteries or other energy storage technologies. During the peak period of grid demand, the energy storage device quickly releases electricity to make up for the load gap.
[0090] This embodiment comprehensively considers the energy storage and release of the nuclear power peak-shaving system based on the key energy storage and release indicator system including three major indicators: waste heat utilization efficiency, storage and release capacity indicators, and nuclear power peak-shaving system stability. It constructs an evaluation framework that integrates the energy storage system and the seawater desalination system into the nuclear power peak-shaving system as a whole; establishes a synergy mechanism between the two systems in the process of energy storage and release, and conducts a quantitative comparison of efficiency through standardized indicators to improve the efficiency of the nuclear power peak-shaving system.
