[0002] In a power system with new energy power generation, pumped storage power stations provide indispensable flexibility resources. Under the action of market free adjustment, it is necessary to determine the power generation time period and pumping time period of each pumped storage unit in the pumped storage power station in advance, that is, to determine the scheduling scheme of each pumped storage unit in the pumped storage power station in advance.

[0003] At present, in the process of determining the scheduling scheme of each pumped storage unit in the pumped storage power station, only the fixed power of each pumped storage unit is used to determine the power generation time period and pumping time period of each pumped storage unit.

[0068] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0069] Before exemplifying specific implementation solutions, the scheduling problem of pumped storage power station is specifically described. The scheduling problem of pumped storage power station is to determine the pumping and generating curve of pumped storage unit in the next scheduling period. The pumping and generating curve of pumped storage unit contains the time period of determining the generating, pumping and idle state of pumped storage unit in the next scheduling period, and gives the generating and pumping power of pumped storage unit in the generating and pumping time period, as shown in the following table. Figure 5 Figure 5 The scheduling result of one pumped storage unit in the future day is shown in the following table. The scheduling result gives the pumping, generating or idle state of pumped storage power station in each unit time period, and gives the pumping or generating power in the pumping and generating state. In the embodiment of the present application, the scheduling problem of pumped storage power station and the meaning of pumping and generating curve in the scheduling period of pumped storage power station are the same, both of which are used to represent the unit time period running state of pumped storage unit in the scheduling period, including the pumping, generating or idle state in each unit time period, and the pumping or generating power in the pumping and generating state. The description hereinafter in the embodiment of the present application is not specially stated.

[0070] The embodiment of the present application provides a scheduling method of pumped storage power station, as shown in the following table. The method comprises the following steps. Figure 1

[0071] 101、obtaining the state transition pumping power and the state transition generating power of each pumped storage unit in the state transition process;

[0072] In the embodiment of the present application, the current execution end obtains the state transition pumping power and the state transition generating power of each pumped storage unit in the state transition process. The pumped storage unit contains three running states: generating state, pumping state and idle state. The generating state is that the generator set of pumped storage power station works in the generating state, at this time, the water energy discharged from the upper reservoir is used to generate electricity, and the generated electric energy is transmitted to the power system. The pumping state is that the pumping unit of pumped storage power station is in the pumping working state, the water of the lower reservoir is pumped to the upper reservoir for storage by using the electricity purchased from the power system. The idle state of pumped storage power station is that the pumped storage unit is not started, neither generating electricity nor pumping water. The three states of pumped storage unit can be converted to each other, that is, the pumped storage unit can be converted from the generating state to the pumping state or the idle state; can be converted from the pumping state to the generating state or the idle state; and can be converted from the idle state to the generating state or the pumping state.

[0073] ​​It should be noted that when the pumped storage unit is converted from the idle state to the pumping state, or from the pumping state to the idle state, it is not instantaneous, but needs to go through a process to achieve it. Similarly, the pumped storage unit is converted from the idle state to the power generation state, or from the power generation state to the idle state, which is not instantaneous, but needs to go through a process to achieve it. The above process is referred to as a state transition process in the embodiments of the present application, which includes the number of state transition duration periods and the pumped storage unit power or the state transition unit period power matched with the number of state transition duration periods. The number of state transition duration periods is used to represent the number of unit periods that need to be crossed during state transition, such as Figure 5 As shown, the number of unit periods that need to be crossed when the pumped storage unit is converted from the idle state to the power generation state is 2; the number of unit periods that need to be crossed when the pumped storage unit is converted from the power generation state to the idle state is 2; the number of unit periods that need to be crossed when the pumped storage unit is converted from the idle state to the pumping state is 1; and the number of unit periods that need to be crossed when the pumped storage unit is converted from the pumping state to the idle state is 1. Since the performance of each pumped storage unit is not the same, the number of unit periods that need to be crossed during the state transition process of each pumped storage unit also differs, which is not limited in the embodiments of the present application. Among them, the pumped storage unit power matched with the state transition duration period is used to represent the pumping capacity of each pumped storage unit during the state transition process, and the state transition unit period power matched with the state transition duration period is used to represent the power generation capacity of each pumped storage unit during the state transition process. For example, Figure 5 The state transition unit period power matched with the state transition duration period when the pumped storage unit is converted from the idle state to the power generation state in the above embodiment is Figure 5 The power generation capacity of the generator set during the start-up process includes two unit periods; the state transition unit period power matched with the state transition duration period when the pumped storage unit is converted from the power generation state to the idle state is Figure 5 The power generation capacity of the generator set during the shutdown process includes two unit periods; the state transition unit period pumping power matched with the state transition duration period when the pumped storage unit is converted from the idle state to the pumping state is Figure 5 The pumping power of the pumped storage unit during the start-up process; the state transition unit period pumping power matched with the state transition duration period when the pumped storage unit is converted from the pumping state to the idle state is Figure 5 The pumping power of the pumped storage unit during the shutdown process, which is not limited in the embodiments of the present application. The power generation capacity of the generator set during the start-up process and the power generation capacity of the generator set during the shutdown process in the above embodiment are summed up to obtain the state transition power generation capacity, that is, the state transition power generation capacity is the sum of the state transition unit period power generation capacity corresponding to the state transition duration period. Similarly, the pumping power of the pumped storage unit during the start-up process and the pumping power of the pumped storage unit during the shutdown process in the above embodiment are summed up to obtain the state transition pumping power.

[0074] It should be noted that, due to the different performance of each pumped storage unit, the pumped storage power and the state transition unit time period of each pumped storage unit also exist differences in the state transition process, and the capacity of each pumped storage unit needs to be set in advance, and the description form can be as follows:

[0075]

[0076] Wherein, P mn,g represents the output of the pumped storage unit g and the generator unit, T mn,g represents the state transition process The number of time periods that need to be continued, represents the state transition process set, which specifically includes four transition processes of generation-idling GA, pumping-idling PA, idling-generation AG and idling-pumping AP; represents the pumped storage power of the state transition duration i, represents the generation power of the state transition duration i, the values of the above pumped storage power and generation power are set based on the specific situation of the actual pumped storage unit, G psh is the set of all pumped storage units in the power system.

[0077] 102, based on the net load value predicted by the power system and the state transition pumped storage power and the state transition generation power, determine the external power purchase amount of the pumped storage power station in the dispatching period;

[0078] In the embodiment of the application, the current execution end determines the external power purchase amount of the pumped storage power station in the dispatching period based on the net load value predicted by the power system and the state transition pumped storage power and the state transition generation power. Wherein, the net load value predicted by the power system is obtained by subtracting the predicted value of the new energy power generation in the power system from the predicted value of the user side load, and the pumped storage curve of the pumped storage unit determined in the embodiment of the application needs to meet the electric energy demand of the net load. According to the principle of power balance in the power system, the sum of the external power purchase amount of the pumped storage power station and the generation power of the generator unit in the pumped storage power station in the dispatching period should be equal to the net load and the pumped storage power of the pumping unit in the pumped storage power station, wherein the generation power of the generator unit in the pumped storage power station is determined by the state transition generation power and the non-state transition generation power, and the pumped storage power of the pumping unit in the pumped storage power station is determined by the state transition pumped storage power and the non-state transition pumped storage power.

[0079] 103, based on the external power purchase amount, determine the power purchase cost of the pumped storage power station, and use a multi-parameter optimization method to optimize and solve the power purchase cost, to obtain the unit time period running state of each pumped storage unit in the dispatching period.

[0080] In the embodiment of the present application, the current execution end determines the power purchase cost of the pumped storage power station based on the external power purchase amount, which comprises obtaining the selling price of the external generator set, and then determining the power purchase cost based on the selling price and the external power purchase amount. The selling price of the external generator set is determined by the selling price declared by the external generator set participating in market competition in the power system in the day-ahead market, which is usually declared in the form of a bid block, for example, a bid block contains the amount of electricity sold by the bid block b and the selling price The power purchase cost is the product of the external power purchase amount and the selling price. It should be noted that, since the selling price and the external power purchase amount of each time period are different, when determining the power purchase cost, the selling price and the external power purchase amount of each time period need to be determined first and multiplied to obtain the power purchase cost of each unit time period, and then the power purchase costs of each unit time period are summed to obtain the power purchase cost of the entire pumped storage power station, which can be expressed by the following formula:

[0081]

[0082] wherein, is the selling price of the external generator set participating in market competition in the power system in the bid block b at time period t, is the set of all bid blocks in unit time period t, and T is the set of all time periods in the dispatching period, is the external power purchase amount of the pumped storage power station at time period t.

[0083] In the embodiment of the present application, the current execution end uses a multi-parameter optimization method to optimize and solve the power purchase cost, and obtains the unit time period operation state of each pumped storage unit in the dispatching period. The multi-parameter optimization method includes but is not limited to least square method, genetic algorithm, gradient descent algorithm, particle swarm optimization algorithm, simulated annealing algorithm, etc., which is not limited in the embodiment of the present application.

[0084] Further, as a refinement and expansion of the specific implementation of the above embodiment, in order to further clarify the calculation method of the external power purchase amount, another pumped storage power station dispatching method is provided, as shown in Figure 2 which determines the external power purchase amount of the pumped storage power station in the dispatching period based on the predicted net load of the power system and the state transition pumped power and the state transition generated power, comprising:

[0085] 201, determining the unit time period net load value based on the unit time period load value and the unit time period new energy generated power of the power system predicted in the dispatching period;

[0086] In the embodiment of the present application, the current execution end determines the unit period net load value based on the unit period load value and the unit period new energy power generation value predicted by the power system in the scheduling period, that is, the unit period net load value is obtained by subtracting the new energy power generation value predicted by the power system in the same unit period from the user side unit period load value predicted by the power system.

[0087] 202, combine the unit period net load value, the state transition unit period pumped hydro power, the state transition unit period power generation value, and the non-state transition unit period pumped hydro power and the non-state transition unit period power generation value in the non-state transition process to determine the unit period external power purchase value;

[0088] In the embodiment of the present application, the current execution end combines the unit period net load value, the state transition unit period pumped hydro power, the state transition unit period power generation value, and the non-state transition unit period pumped hydro power and the non-state transition unit period power generation value in the non-state transition process to determine the unit period external power purchase value. That is, according to the principle of power balance in the power system, the sum of the external power purchase value of the pumped storage power station and the power generation value of the generator set in the pumped storage power station in the scheduling period should be equal to the net load and the pumped hydro power of the pumped storage unit in the pumped storage power station, wherein the power generation value of the generator set in the pumped storage power station is determined by the state transition power generation value and the non-state transition power generation value, and the pumped hydro power of the pumped storage unit in the pumped storage power station is determined by the state transition pumped hydro power and the non-state transition pumped hydro power.

[0089] It should be noted that the principle of power balance in the power system can be represented by the following formula:

[0090]

[0091] Wherein, is the external power purchase value of the pumped storage power station at time period t; is the set of all bid blocks in unit time period t; G psh is the set of all pumped storage units in the pumped storage power station; is the net load value of unit time period t; is the power generation value of pumped storage unit g in unit time period t; is the pumped hydro power of pumped storage unit g in unit time period t; represents the pumped hydro power of state transition duration period i, and for a determined transition The value is determined in advance based on the performance of the unit; represents the power generation value of state transition duration period i; T mn,g represents the state transition process The number of time periods that need to be continued; is the set of state transition processes; Let g, g∈G represent the pumped storage unit. psh At time t, whether the state is transitioning from state m to state n is a 0-1 variable. This indicates that the pumped-storage unit g is in the transition from state m to state n at time t; otherwise, it indicates that it is not in the transition. T is the set of all time periods within the scheduling cycle. Based on the above formula, the external power purchase of the pumped-storage power station at time period t can be derived. This refers to the amount of electricity purchased from external sources per unit time period; however, this embodiment of the invention does not impose specific limitations on this.

[0092] 203. Statistically calculate the external power purchases for all unit time periods within the scheduling cycle to obtain the external power purchases for the pumped storage power station within the scheduling cycle.

[0093] In this embodiment of the invention, the current execution terminal counts the externally purchased electricity volume for all unit time periods within the scheduling cycle to obtain the externally purchased electricity volume of the pumped storage power station within the scheduling cycle, which is expressed by the following formula:

[0094]

[0095] It should be noted that the externally purchased electricity volume per unit time period in the above formula is... Derived from the formula in step 202, therefore, the externally purchased electricity... The expression contains other variables from the formula in step 202, such as... The embodiments of the present invention are not specifically limited.

[0096] Furthermore, as a refinement and extension of the specific implementation of the above embodiments, in order to ensure that the relevant parameters adjusted by the multi-parameter optimization method are within a certain range and meet the normal operation requirements of the pumped storage power station, another scheduling method for the pumped storage power station is provided. Before using the multi-parameter optimization method to optimize and solve the electricity purchase cost, the method further includes:

[0097] Constraints are set for relevant parameters in the electricity purchase cost, including state transition constraints, state maintenance time constraints, pumped storage unit rated power constraints, reservoir energy storage constraints, reservoir operation status constraints, and external electricity purchase constraints.

[0098] In this embodiment of the invention, the current execution terminal sets constraints on relevant parameters in the electricity purchase cost, including state transition constraints, state maintenance time constraints, rated power constraints of pumped storage units, reservoir energy storage constraints, reservoir operation status constraints, and external electricity purchase constraints.

[0099] The state transition constraint condition is used for constraining the state of the pumped storage unit, and ensures that the pumped storage unit can only be in one of the states of power generation, pumping and idling in each unit time period t. The constraint condition is expressed by a formula as follows:

[0100]

[0101] wherein, is an expression of the pumped storage unit g in state m at time t, and is a 0-1 variable, represents the pumped storage unit g G psh in state m M at time t, g which includes both that the pumped storage unit has reached state m and the transition process of transferring from another state to state m, and the value is 1. not in state m M g ; M g ={Gen, Pump, Alloff} represents a set of states allowed by the pumped storage unit, specifically including power generation Gen, pumping Pump and idling Alloff; G psh is a set of all pumped storage units in the system; and T is a set of all time periods in the scheduling period.

[0102] In addition, the state transition constraint condition is also used for constraining the transition of the pumped storage unit in the unit time period, and ensures that the pumped storage unit can only have one specific transition in each unit time period t. The constraint condition is expressed by a formula as follows:

[0103]

[0104] wherein, represents the pumped storage unit g, g G psh whether in the process of transferring from state m to state n in the unit time period t, and is a 0-1 variable; represents that the pumped storage unit g is in the process of transferring from state m to state n in the unit time period t, otherwise represents that it is not in the process of transferring; represents a set of states that can be transferred from state m, for example, the pumped storage unit can only be transferred to the idling state in the power generation state, and can only be transferred to the idling state in the pumping state, and can be transferred to the power generation state or the pumping state in the idling state; G psh is a set of all pumped storage units in the system; and T is a set of all time periods in the scheduling period.

[0105] It should be noted that the above expression of the pumped storage unit g in state m at time t and the pumped storage unit g, g G pshan indicator of whether the unit is in the process of transitioning from state m to state n at time period t The relationship between them can be expressed as:

[0106]

[0107] wherein, an indicator of whether the pumped storage unit g is in state m at time period t-1; pumped storage units g, g∈G psh an indicator of whether the unit is in the process of transitioning from state n to state m at time period t-1.

[0108] In the embodiments of the present application, the state maintenance time constraint condition is used to constrain the minimum time that each state of the pumped storage unit lasts, to ensure that the time that the pumped storage unit lasts in each state is greater than or equal to the minimum duration time, and the constraint condition is expressed by a formula as follows:
