Description

Technical Field

[0001] The present invention relates to the field of new energy and energy-saving technologies, and in particular to a scheduling method and device for energy equipment and a non-volatile storage medium. Background Art

[0002] An integrated energy system with multi-energy coupling and coordinated supply is one of the key technical directions to alleviate the contradiction between energy supply and demand and promote low carbonization, and it is also one of the important development trends in the energy field. The integrated energy system includes multiple subsystems such as electrical cooling and heating. For example, the power supply subsystem needs to achieve real-time balance of electric energy, so its scheduling time interval is usually in seconds or minutes, which belongs to a fast dynamic system; while the heating and gas supply subsystems are usually scheduled in hours due to factors such as the pipe storage characteristics of gas pipelines, thermal inertia of heat networks and building complexes, and belong to a slow dynamic system. Due to the differences in the scheduling time intervals of various equipment and their respective operating characteristics, the scheduling optimization problem of the integrated energy system becomes very complicated, involving optimization problems of multiple time scales and multiple energy flows.

[0003] At present, the intraday two-layer optimization model of the integrated energy system has the following main shortcomings: ① The scheduling model has a single time scale. The existing technology often adopts a scheduling model with a single time scale, which cannot effectively take into account the differences in the fast and slow dynamic characteristics of different subsystems in the integrated energy system. This leads to the inability to fully consider the coordinated operation between different subsystems in the scheduling process, affecting the scheduling effect and the overall performance of the system; ② Lack of dynamic time interval scheduling method. The existing technology often adopts a fixed scheduling time interval, and cannot flexibly adjust the time interval according to the real-time operation situation. Due to the complexity and dynamics of the integrated energy system, the fixed time interval scheduling method may not be able to effectively respond to the real-time changes in the system operation, affecting the flexibility and adaptability of the scheduling.

[0031] Figure 2 is a flow chart of a method for dispatching energy equipment according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0032] Step S201, obtaining the predicted output power corresponding to each of the cold and heat energy equipment and the electric energy equipment in the target energy system on the day.

[0033] In this step, the target energy system may be a comprehensive energy system, and the cold and heat energy equipment and the electric energy equipment are part of the comprehensive energy system. Figure 3 1 is a diagram of a multi-region integrated energy system architecture provided according to an optional embodiment of the present invention. Figure 3 As shown in the figure, the integrated energy system includes three subsystems: cooling, heating and electricity. The energy input ends mainly include grid electricity, distributed energy (DG), gas turbines (GT), gas boilers (GB) and fuel cells (FC). The communication equipment of each system mainly includes electric boilers (EB), electric refrigerators (EC) and absorption refrigerators (AC). Each subsystem is equipped with energy storage equipment, which are batteries, heat storage tanks and cold storage tanks. Among them, the cooling and heating energy equipment includes gas turbines, gas boilers, electric boilers, electric refrigerators and absorption refrigerators, and the electric energy equipment includes distributed energy and fuel cells. The integrated energy system also includes electric loads, cooling loads, heat loads and system loads. The system load includes uncontrollable basic loads and controllable flexible loads, among which the flexible loads include: shiftable loads, transferable loads and reducible loads. In the scheduling of the energy system, the system operation status of the previous day can be used to predict the system scheduling status of the day and generate a day-ahead scheduling plan. The day-ahead scheduling plan can include the predicted output power of each device, the scheduling of energy storage equipment and the operating status of the load. Among them, considering the complexity of load switching and operation, the operating status of load that can be cut, load that can be shifted, and load that can be transferred are all determined by the day-ahead dispatch plan and do not participate in the correction of the day-ahead forecast value within the day. Similarly, in the correction of the day-ahead dispatch plan within the day, due to frequent power fluctuations, the energy storage equipment has basically reached the maximum number of charge and discharge times in the day-ahead dispatch plan. Therefore, the energy storage equipment does not participate in the correction of the day-ahead forecast value within the day.

[0034] Step S202: input the predicted output power of the cold and heat energy equipment within a first preset time period from the current moment into the cold and heat energy scheduling model to determine a correction value of the predicted output power of the cold and heat energy equipment within the first preset time period from the current moment.

[0035] In this step, the goal of the cold and heat energy scheduling model is to ensure the lowest operating cost of the cold and heat energy equipment, and to schedule the cold and heat energy equipment while meeting the constraints of the operation of the cold and heat energy equipment, so as to obtain the optimal output power of the cold and heat energy equipment. The content that the cold and heat energy scheduling model wants to adjust can be the correction of the day-ahead scheduling plan. The predicted output power of the cold and heat energy equipment from the current moment through the first preset time length in the day-ahead scheduling plan is input into the cold and heat energy scheduling model to obtain the cold and heat energy predicted output power correction value of the cold and heat energy equipment from the current moment through the first preset time length. For example, the first preset time length can be 1 hour. Within 1 hour, the system scheduling plan in the prediction domain and the control domain can be obtained. The scheduling plan of the control domain is executed according to the obtained cold and heat energy predicted output power correction value, and it is sent to the lower-level electric energy scheduling model to wait for its scheduling end instruction. At the same time, the prediction domain and the control domain are rolling optimized to the next first preset time length. Among them, the control domain and prediction domain are both concepts related to time. The time scale of the control domain and prediction domain of the upper-level cold and hot energy scheduling model is 1 hour; the time scale of the control domain and prediction domain of the lower-level electric energy scheduling model is 15 minutes; prediction is to predict the load information of the next time period, and control is to solve the optimization model based on the predicted load information, which can be understood as tracking control.

[0036] Step S203: Based on the predicted output power correction value of the cold and heat energy, the output power of the cold and heat energy equipment in the first preset time period starting from the current moment is adjusted, and a start instruction is generated.

[0037] In this step, according to the correction value of the predicted output power of the cold and heat energy, the scheduling plan corresponding to the predicted output power of the cold and heat energy equipment within the first preset time period from the current moment is adjusted, and the cold and heat energy equipment is scheduled to obtain the optimal output power of the cold and heat energy equipment within the first preset time period. At the same time, the optimization result is sent to the lower-level power scheduling model, and a start instruction is generated to start the work of the lower-level power scheduling model.

[0038] Step S204, based on the start instruction, input the cold and heat energy predicted output power correction value and the predicted output power of the electric energy equipment from the current moment to the second preset time length into the electric energy scheduling model, and determine the first electric energy predicted output power correction value of the electric energy equipment from the current moment to the second preset time length, wherein the first preset time length is greater than the second preset time length.

[0039] In this step, the goal of the electric energy scheduling model is to ensure the lowest operating cost of the electric energy equipment, and to schedule the electric energy equipment while satisfying the constraints of the operation of the electric energy equipment, so as to obtain the optimal output power of the electric energy equipment. The content that the electric energy scheduling model wants to adjust can be the correction of the day-ahead scheduling plan. The predicted output power of the electric energy equipment from the current moment to the second preset time length in the day-ahead scheduling plan is input into the electric energy scheduling model to obtain the first electric energy predicted output power correction value of the electric energy equipment from the current moment to the second preset time length. For example, the second preset time length can be 15 minutes. The lower-level electric energy scheduling model waits for the scheduling plan instruction of the upper-level model control domain. Within 15 minutes, the first electric energy predicted output power correction value of the electric energy equipment from the current moment to the second preset time length is obtained. According to the corrected value of the predicted output power, the optimal scheduling strategy of the current layer of the electric system is determined.

[0040] Step S205: Based on the first electric energy predicted output power correction value, the output power of the electric energy equipment within a second preset time period starting from the current moment is adjusted.

[0041] In this step, based on the first electric energy predicted output power correction value, the scheduling plan corresponding to the predicted output power of the electric energy equipment within the second preset time period starting from the current moment is adjusted, and the electric energy equipment is scheduled to obtain the optimal output power of the electric energy equipment within the second preset time period.

[0042] Through the above steps, the purpose of dividing the intraday scheduling model into two layers, adopting scheduling time intervals of different lengths, dynamically adjusting the time intervals, and rollingly revising the day-ahead plan is achieved, thereby achieving the technical effect of improving the flexibility and adaptability of the integrated energy system scheduling, and further solving the technical problem of low scheduling flexibility and adaptability caused by using a single time scale and fixed time interval to schedule different energy equipment.

[0043] As an optional embodiment, the predicted output power of the cold and heat energy equipment and the electric energy equipment in the target energy system on the day is obtained, including: based on the output power of the cold and heat energy equipment and the electric energy equipment on the previous day, determining the predicted output power of the cold and heat energy equipment and the electric energy equipment on the day.

[0044] Optionally, the predicted output power of the cold and heat energy equipment and the electric energy equipment corresponding to each other on the same day can be obtained through the day-ahead scheduling plan. The day-ahead scheduling plan refers to the planning and arrangement of the operation of various links such as power generation, transmission, transformation, and distribution on the next day based on load demand, power generation capacity and other relevant factors one day before the operation of the energy system, with the aim of ensuring the balance between power supply and demand and reducing operating costs to a certain extent. The day-ahead scheduling plan in the embodiment of the present invention may include energy storage scheduling, flexible load, planned output of hot and cold energy equipment and planned output of electric energy equipment, wherein the planned output of hot and cold energy equipment and the planned output of electric energy equipment represent the predicted output power of the cold and heat energy equipment and the electric energy equipment corresponding to each other on the same day.

[0045] As an optional embodiment, before the predicted output power of the cold and heat energy equipment within a first preset time period starting from the current moment is input into the cold and heat energy scheduling model, it includes: determining the cold and heat energy scheduling model based on a first preset relationship and a first constraint condition, wherein the first preset relationship is used to calculate the minimum total cost of the cold and heat energy equipment operation, and the first constraint condition includes a constraint on the operating power of the cold and heat energy equipment and a constraint on the inflow power and outflow power of the cold and heat bus.

[0046] Optionally, the objective function of the cold and heat energy scheduling model mainly considers the total cost of cold and heat energy equipment scheduling, including: gas turbine operating cost; gas boiler operating cost; electric boiler operating cost; electric refrigerator operating cost; absorption refrigerator operating cost; gas turbine power generation income; electric boiler power consumption cost; electric refrigerator power consumption cost. The constraints of the cold and heat energy scheduling model mainly include cold and heat energy equipment operation constraints and cold and hot bus power balance constraints.

[0047] For example, the objective function of the cooling and heating energy scheduling model can be:

[0048]

[0049] in, They are the incremental operating costs of gas turbines, gas boilers, electric boilers, electric chillers, and absorption chillers, respectively, and their calculation methods are consistent with day-ahead dispatch; The incremental revenue from electricity generation from gas turbines; and They are the incremental electricity consumption costs of electric boilers and electric refrigerators during the daily period, and are calculated as follows:

[0050]

[0051] in, is the average price of electricity purchased, The power increment of the gas turbine; and The increase in power consumption of electric boilers and electric refrigerators.

[0052] The constraints for building the cooling and heating energy scheduling model can include the following steps:

[0053] The operation constraints of the cold and heat energy equipment must be met, that is, after the power is adjusted, the output of each device, that is, the output power, cannot exceed the upper and lower limits of the output, so it should meet the following requirements:

[0054]

[0055] in, They are the day-ahead dispatching planned outputs of gas turbines, gas boilers, electric boilers, electric refrigerators, and absorption refrigerators; The output of each device should also meet the up and down ramp rates, so it should meet:

[0056]

[0057] To meet the power balance of the thermal bus, that is, to maintain the balance between the power flowing into and out of the thermal bus, the following conditions should be met:

[0058]

[0059] in, is the heat production power increment of the gas turbine; is the heat consumption power increment of the absorption refrigerator; The power increment required for heat load in short-term forecast and day-ahead forecast.

[0060] To meet the power balance of the cooling bus, that is, to maintain the balance between the power flowing into and out of the cooling bus, the following conditions should be met:

[0061]

[0062] in, The power increment required for cooling load in short-term forecast and day-ahead forecast.

[0063] As an optional embodiment, before the predicted output power correction value of cold and heat energy and the predicted output power of the electric energy equipment within a second preset time period from the current moment are input into the electric energy scheduling model based on the start instruction, it includes: determining the electric energy scheduling model based on a second preset relationship and a second constraint condition, wherein the second preset relationship is used to calculate the minimum total cost of the operation of the electric energy equipment, and the second constraint condition includes a constraint on the operating power of the electric energy equipment, a constraint on the power inflow and outflow of the power bus, and a constraint on the power of the power interconnection line.

[0064] Optionally, the objective function of the power dispatch model mainly considers the total cost of power equipment dispatch, including: system power purchase cost; distributed power supply operation cost; fuel cell cost. The constraints of the lower-level power dispatch model described in the present invention mainly include power connection line constraints between the power grid and the system; distributed power supply output constraints; fuel cell output constraints; power bus power balance constraints.

[0065] For example, the objective function of the power dispatch model can be:

[0066]

[0067] in, The incremental cost of purchasing electricity for the system. The incremental operating cost of distributed power generation is is the incremental cost of fuel cells, The calculation is consistent with that of day-ahead scheduling.

[0068] The constraints of the power dispatch model can be constructed by the following steps:

[0069] The power tie line constraints between the power grid and the system must be met. After the power purchase and sales of the system change, it still cannot exceed the maximum power allowable value of the tie line between the power grid and the system, and the tie line cannot be in the power purchase and sales state at the same time during the same period, that is, it must meet the following requirements:

[0070]

[0071] in, and are the increments of purchased and sold electricity power respectively; and They are the transaction status of purchasing and selling electricity respectively.

[0072] Meet the output constraints of distributed power sources. After power adjustment, the output of wind turbines and photovoltaic units, that is, the output power, should not exceed the maximum output allowed in each period, so it should meet the following requirements:

[0073]

[0074] in, and They are the day-ahead dispatch plan outputs of wind turbines and photovoltaics respectively; and are the output increments of wind turbines and photovoltaics respectively; and They are the daily dispatch forecast values ​​of wind turbines and photovoltaics respectively.

[0075] Meet the fuel cell output constraints. After power adjustment, the fuel cell output cannot exceed the upper and lower limits of the output, and should meet the maximum up and down ramp rates, and should meet:

[0076]

[0077] in, Contribute to the day-ahead dispatch plan for fuel cells; Increase the output of fuel cells; It is the start and stop state of the fuel cell; △t2=15min.

[0078] Satisfy the power bus power balance constraint. According to the power bus inflow and outflow power balance, it should satisfy:

[0079]

[0080] in, It is the difference between the short-term forecast of electric load and the day-ahead forecast in the jth period.

[0081] As an optional embodiment, the moment after the current moment has passed the second preset time period is determined as the first moment; at the first moment, the predicted output power correction value of cold and heat energy and the predicted output power of the electric energy equipment from the first moment to the second preset time period are input into the electric energy scheduling model to determine the second electric energy predicted output power correction value of the electric energy equipment from the first moment to the second preset time period; based on the second electric energy predicted output power correction value, the output power of the electric energy equipment from the first moment to the second preset time period is adjusted; and the above steps are repeated until the first preset time period has passed from the current moment.

[0082] Optionally, since the response rate of the cold and heat energy equipment is slow, while the response rate of the electric energy equipment is fast, if a single time interval is used as the preset duration of the scheduling, the coordinated operation between the cold and heat energy system and the electric energy system cannot be fully considered during the scheduling process, affecting the scheduling effect and the overall performance of the system. Therefore, different time intervals can be set as the preset duration of the scheduling. For the cold and heat energy scheduling model, the operation time interval is the first preset duration, which can be 1 hour. For the electric energy scheduling model, the operation time interval is the second preset duration, which can be 15 minutes. Therefore, the time window of the electric energy scheduling is short. After multiple time windows are dynamically rolled and optimized, when the time window of the electric energy scheduling overlaps with the end time of the time window of the cold and heat energy scheduling, the rolling optimization is stopped. Among them, the overlap means that the electric energy scheduling time is 15 minutes, the cold and heat energy scheduling time is 1 hour, and the time for the electric energy scheduling model to complete 4 15-minute rolling scheduling is consistent with the time for the cold and heat energy scheduling model to complete 1 hour scheduling.

[0083] As an optional embodiment, in the case where a first preset time has passed from the current moment, the method includes: determining the moment after the first preset time has passed from the current moment as the second moment; generating a rolling instruction; based on the rolling instruction, starting from the second moment, repeating the above steps within the previous first preset time, and adjusting the output power of the cold and heat energy equipment from the second moment after the first preset time and the output power of the electric energy equipment from the second moment after the second preset time.

[0084] Optionally, when the time window for electric energy scheduling overlaps with the end time of the time window for cold and hot energy scheduling, the rolling optimization is stopped, and a rolling instruction is sent to the cold and hot energy scheduling model to enter the next time window of the cold and hot energy scheduling model, i.e., repeated scheduling and execution within 1 hour, thereby realizing dynamic rolling scheduling of equipment in each subsystem in the energy system. Figure 4 is a time domain control strategy diagram for intraday scheduling of an integrated energy system based on model predictive control according to an optional embodiment of the present invention, such as Figure 4 As shown in the figure, for the upper-level cold and heat energy scheduling model, the time interval is 1h. The system scheduling plan in the prediction domain and the control domain is obtained within the time interval. The scheduling plan of the control domain is executed according to the optimization result, and it is sent to the lower-level electric energy scheduling model, waiting for its scheduling end instruction; the prediction domain and the control domain are rolling optimized to the next time interval, and the above process is repeated. For the lower-level electric energy scheduling model, the time interval is 15min, waiting for the control domain scheduling plan instruction of the upper-level model, and determining the optimization scheduling strategy of the electric system at this level based on it. The lower-level scheduling time window is short. After dynamic rolling optimization of multiple time windows, when the lower-level scheduling time window overlaps with the end time of the upper-level time window, the rolling optimization is stopped, and the scheduling end instruction is sent to the upper layer, and the next time window of the upper layer is entered to repeat scheduling and execution. Among them, the control domain and prediction domain time scales of the upper-level cold and heat energy scheduling model are 1 hour; the control domain and prediction domain time scales of the lower-level electric energy scheduling model are 15min; prediction is to predict the load information of the next period, and control is to solve the optimization model based on the predicted load information, which can be understood as tracking control.

[0085] As an optional embodiment, the present invention provides a daily double-layer dynamic rolling planning model for an integrated energy system based on model predictive control. Figure 5 : is a two-layer scheduling strategy diagram for a comprehensive energy system based on model predictive control according to an optional embodiment of the present invention. Figure 5As shown, the forecast objects of day-ahead dispatch can include photovoltaic, wind farms and loads, and the day-ahead dispatch plan can include energy storage dispatch, flexible load, planned output of thermal energy equipment, and planned output of cooling energy equipment. The upper-level dispatch model is designed to handle the fluctuations of cooling and heating power with a slower response rate. The forecast object is the hot and cold load. The variables can be GT output, GB output, EB output, AC output and EC output. The constraints used are related to equipment operation and bus power balance. The lower-level dispatch model is used to control the fluctuations of electric power with a faster response rate. The forecast object is distributed power sources. The variables can be power purchase and sale, DG output and FC output. The constraints used are related to DG operation, FC operation and bus power balance.

[0086] The process is based on the day-ahead scheduling plan. The fast and slow layers adopt different scheduling time interval lengths, and establish the instruction cycle time interval decision index in the slow layer. Through the rolling update of the distributed power output and the ultra-short-term prediction information of the load power, the day-ahead plan value is corrected in an incremental balance manner, and the output of the controllable components in the system is adjusted to achieve dynamic correction of the slow layer instruction cycle time. Compared with the related art, the present invention can have many advantages. For example, the decision index of the dynamic time interval can determine whether the system needs to issue an adjustment instruction according to the system state: when the system deviation is large, it can help real-time scheduling; when the system deviation is small, it can reduce unnecessary scheduling. For another example, the order of optimizing cold and hot gas energy at the upper scale and optimizing electric energy at the lower scale is adopted to realize the hierarchical management of energy, solving the problem of time scale selection of multi-modal heterogeneous systems. In addition, the energy difference characteristics can be maximized. The upper layer uses 1h as the scheduling time base and adds a dynamic time interval. The lower layer uses 15min as the scheduling time interval to meet the requirements of electrical real-time energy balance, which can take into account the optimization of supply and demand balance and equipment adjustment times at the same time.
