[0125] In order to facilitate understanding of the above technical solutions of the present invention, the above technical solutions of the present invention are further described from the perspective of architecture and principle as follows:

[0126] The present invention provides a multi-scenario oriented multi-resource collaborative control method and system, which realizes the collaborative calling of multiple types of resources that meet the needs of multiple control scenarios.

[0127] In a first aspect, the present invention provides a multi-scenario multi-resource collaborative control method, comprising the following steps:

[0128] Step 1: Establish a multi-resource hierarchical control architecture including a collaborative control layer and a resource control layer, and implement independent modeling of different types of regulation resources through conventional AGC (automatic generation control), new energy AGC and energy storage AGC of the resource control layer, and set the control mode according to the regulation requirements.

[0129] 1. Multi-resource hierarchical control overall architecture

[0130] The overall architecture of multi-resource collaborative control includes a collaborative control layer and a resource control layer. The collaborative control layer coordinates control targets such as peak load regulation, frequency regulation, and cross-section, generates collaborative control information, and realizes collaborative control of the resource control layer. The resource control layer is composed of conventional AGC, new energy AGC, and energy storage AGC. According to the collaborative control information generated by the collaborative control layer, control instructions for different types of resources are generated and sent to the site. Among them, conventional AGC realizes the modeling and control of conventional resources such as thermal power, hydropower, and nuclear power; new energy AGC realizes the modeling and control of wind power and photovoltaic resources; and energy storage AGC realizes the modeling and control of new energy storage resources.

[0131] 2. Resource Control Layer Control Model

[0132] Conventional AGC, new energy AGC and energy storage AGC control models all use a two-layer model of control object and group:

[0133] (1) The control object is the smallest unit for monitoring and controlling various resources. The model dimensions of various resource control objects support single-machine modeling and full-station modeling. Generally speaking, thermal power, hydropower, nuclear power, and pumped storage are modeled in a single-machine manner, while new energy and energy storage are modeled in a station manner.

[0134] (2) Groups are used to classify control objects according to control scenarios, aggregate the operating information of control objects within the group, and participate in the allocation of control requirements in the corresponding scenarios of the collaborative control layer. Groups can be flexibly set to correspond to different control scenarios. The general settings are: peak-shaving group N, frequency-shaving group N, and test group N. Among them, the peak-shaving group contains control objects participating in peak-shaving control, the frequency-shaving group contains control objects participating in frequency-shaving control, and the test group contains control objects that do not participate in collaborative control due to performance testing, abnormalities, etc. All resources participate in section control by default, and there is no need to set up separate groups. If there are other control requirements, group settings can be flexibly increased.

[0135] Conventional AGC, new energy AGC and energy storage AGC also model the information required for section control: mainly including the section-control object association relationship, section control margin, and the sensitivity of the active output of the control object to the section.

[0136] 3. Resource Control Layer Control Mode

[0137] Corresponding to the two-layer model, the control modes of conventional AGC, new energy AGC and energy storage AGC include group control mode and control object control mode.

[0138] (1) Group control mode

[0139] Group control modes include: frequency regulation control, peak regulation control, plan tracking, manual setting, free generation, rated charge, rated discharge, etc. The regulation demand calculation method is different under different control modes. The group control mode in each AGC is independently set according to resource characteristics and regulation scenarios:

[0140] a) Conventional AGC group control modes can be set: frequency modulation control, plan tracking, manual setting, etc.

[0141] b) New energy AGC group control mode can be set: peak load control, manual setting point, free power generation, etc.

[0142] c) The energy storage AGC group control mode can be set: frequency modulation control, plan tracking, manual setting point, rated charge, rated discharge, etc.

[0143] (2) Control object control mode

[0144] The control modes of the control object include: automatic, local, and pause. The control object with automatic control mode follows the control mode of the group to which it belongs and participates in group control according to the control strategy corresponding to the group control mode. The control object with local and pause control modes does not participate in group command allocation.

[0145] Step 2: According to the characteristics of different types of resources and control scenarios, set the model association relationship and control mode in conventional AGC, new energy AGC and energy storage AGC respectively. Conventional AGC, new energy AGC and energy storage AGC calculate the adjustable information of various types of resources in different scenarios respectively, and the collaborative control layer obtains it in real time.

[0146] 1. Conventional AGC, new energy AGC and energy storage AGC model association and control mode setting

[0147] In conventional AGC, new energy AGC and energy storage AGC, various regulation resources participate in different regulation scenarios through model association settings and control mode settings:

[0148] (1) The regulation resources involved in frequency modulation are placed in a separate frequency modulation group as control objects. The group control mode is set to frequency modulation control, and the control object control mode is set to automatic.

[0149] (2) The regulating resources that perform peak load regulation by tracking the market clearing results such as the planned output curve and the electric energy market / peak load auxiliary service market are placed in a separate peak load regulation group as control objects. The group control mode is set to planned tracking, and the control object control mode is set to automatic.

[0150] (3) The new energy stations that participate in peak load regulation according to the real-time absorption capacity of the power grid are placed in a separate peak load regulation group as control objects. The group control mode is set to peak load regulation control, and the control object control mode is set to automatic.

[0151] (4) The regulatory resources involved in cross-sectional correction are associated through the cross-sectional model.

[0152] 2. Adjustable information obtained in real time by the collaborative control layer

[0153] The collaborative control layer obtains the following information from the resource control layer in real time:

[0154] (1) Conventional AGC and energy storage AGC respectively calculate the frequency regulation information such as the regulation range, real-time output, and frequency regulation standby of the frequency regulation group.

[0155] (2) The new energy AGC calculates the peak-shaving group’s regulation range, real-time output and other new energy peak-shaving information.

[0156] (3) The equivalent downward adjustment step length for each type of resource in each section calculated by conventional AGC, new energy AGC and energy storage AGC respectively, and other section control information. The equivalent downward adjustment step length in the section is the effective adjustment step length for the section after conversion according to the sensitivity and the actual downward adjustment step length.

[0157] Step 3: The collaborative control layer calculates the total frequency regulation demand and allocates it to various resources according to the frequency regulation demand allocation strategy, generates frequency regulation collaborative control information, and sends it to the conventional AGC and energy storage AGC.

[0158] 1. Calculation of total frequency regulation demand

[0159] The frequency modulation demand is reflected as the regional control deviation ACE, and the following three regional control modes are supported to calculate ACE.

[0160] (1) Tie-line and frequency deviation control (TBC) mode: ACE = 10B*(f-f0)+(I-I0), where B is the regional frequency deviation coefficient (MW / 0.1Hz), f is the measured system frequency (Hz), and f0 is the rated frequency (Hz); I is the sum of the actual active power of the regional tie-line (MW), and I0 is the regional planned net exchange power (MW). The actual active power of the tie-line and the regional planned net exchange power are positive when sent out and negative when received.

[0161] (2) Constant frequency control (FFC) mode: ACE = 10B*(f-f0), where B is the regional frequency deviation coefficient (MW / Hz), f is the measured system frequency (Hz), and f0 is the rated frequency (Hz).

[0162] (3) Constant tie-line exchange power control (FTC) mode: ACE = (I-I0), where I is the sum of the actual active power of the regional tie-lines (MW), and I0 is the regional planned net exchange power (MW). The actual active power of the tie-lines and the regional planned net exchange power are positive when sent out and negative when received.

[0163] 2. Allocation of total frequency modulation demand

[0164] like Figure 4 As shown in the figure, the total frequency regulation demand is allocated between the thermal power units and energy storage power stations participating in the frequency regulation. The allocation coefficients of thermal power frequency regulation demand and energy storage frequency regulation demand are set as k p , k e , then the frequency regulation demand allocated to thermal power is: R p =-k P *ACE, the frequency regulation demand allocated to energy storage is R e =-k e *ACE.

[0165] Set threshold values ​​ACE1 and ACE2 (|ACE1|<|ACE2|) respectively, divide the operating area into a normal area (|ACE|<|ACE1|), a secondary emergency area (|ACE1|<|ACE|<|ACE2|), and an emergency area |ACE|>|ACE2|) according to the size of ACE, and call different types of resources in different areas.

[0166] (1) In the normal area: the thermal power unit is responsible for frequency regulation, and k can be set p =1, k e =0.

[0167] (1) Secondary emergency zone: Energy storage assists thermal power units in participating in frequency regulation, and k can be set p =0.6, k e =0.4.

[0168] (3) Emergency zone: The energy storage plays a rapid regulatory role in pulling the ACE back to the normal zone. The k p =0.3, k e =0.7.

[0169] k p , k e The specific settings can be adjusted according to the actual frequency regulation capacity of thermal power and energy storage.

[0170] The collaborative control layer generates the frequency modulation collaborative control information, i.e., the thermal power frequency modulation demand k p and energy storage frequency regulation demand k e , sent to the conventional AGC and energy storage AGC respectively.

[0171] Step 4: The collaborative control layer calculates the total demand for new energy peak load regulation and generates peak load collaborative control information, which is sent to the new energy AGC.

[0172] like Figure 5 As shown, thermal power, pumped storage, and energy storage participate in peak load regulation according to the clearing value or planned value of the electricity market. Due to the forecast deviation, the real-time peak load demand is shared by new energy. The peak load demand of new energy is generated according to the reserve under the frequency regulation of the whole network and / or the reserve under the frequency regulation of thermal power. When the reserve under the frequency regulation of the whole network is lower than the set threshold value K1 or the reserve under the frequency regulation of thermal power is lower than the set threshold value K2, new energy participates in peak load regulation. The formula for calculating the peak load demand of new energy is as follows:

[0173] R 新能源调峰 = Thermal power frequency regulation real-time reserve - thermal power frequency regulation reserve threshold

[0174] The collaborative control layer generates the peak load collaborative control information, i.e., the total peak load demand of new energy R 新能源调峰 Send to New Energy AGC.

[0175] Step 5: The collaborative control layer calculates the section control requirements based on the section operation status and generates section collaborative control information, which is sent to the conventional AGC, energy storage AGC, and new energy AGC.

[0176] 1. Section control requirements

[0177] The collaborative control layer obtains the section overload status information and section limit from the section monitoring module. When the section is overloaded, the section control is started. The section control includes the following two types:

[0178] (1) Prohibit upward control under the overload state of the section, that is, the collaborative control layer generates a prohibit upward flag for the overload section, which is used to block the control instructions of all deteriorated section states, that is, to block the upward adjustment instructions of the control object under the section.

[0179] (2) Correction control under section overload condition, that is, the collaborative control layer generates section correction demand, and the calculation formula is as follows:

[0180] R sec =(1-δ%)*P lmt -P sec,t ; In the formula, R sec is the cross-section correction amount, δ is the reserved safety margin, P sec,t is the actual flow of the section at time t, P lmt It is the section limit.

[0181] 2. Allocation of Section Correction Demand

[0182] The collaborative control layer determines the resource type under the section based on the section-control object association relationship obtained from conventional AGC, energy storage AGC, and new energy AGC: When there is only one type of resource under the section, only this type of resource can bear the correction demand of the section. If multiple types of resources are involved in the same section, the following section correction demand allocation process is executed:

[0183] 1) When the reserve under the frequency regulation of the whole network and / or the reserve under the frequency regulation of thermal power is lower than the threshold value, the section correction demand shall be borne by the new energy station under the section; the collaborative control layer shall send the generated section collaborative control information, i.e. the over-limit section and the over-limit section correction demand, to the new energy AGC. The new energy AGC shall adjust the new energy station under the section down one step in sequence according to the sensitivity from high to low until the section correction demand is met.

[0184] 2) When the reserve under the whole network frequency regulation and / or the reserve under the thermal power frequency regulation is higher than the threshold value, the section correction demand is allocated according to the ACE direction, specifically:

[0185] (1) When the section exceeds the limit and ACE>0, that is, the frequency regulation direction is the same as the section correction demand direction, the section correction demand is borne by the frequency regulation resources under the section: the collaborative control layer sends the generated section collaborative control information, that is, the flag bit of the section exceeding the limit and the section correction demand in the same direction, to the conventional AGC and energy storage AGC.

[0186] (2) When the section exceeds the limit and ACE < 0, that is, the frequency modulation direction is opposite to the direction required for section correction:

[0187] If the section correction demand < β*minimum pumped storage call-up amount (β is the pumped storage correction coefficient): allocate in the order of thermal power, energy storage, and new energy. If the equivalent downward adjustment step of the priority resource is less than the section correction demand, then this type of resource will bear the section correction demand; otherwise, this type of resource will bear the section correction demand according to the equivalent downward adjustment step, and the rest will be allocated to the next type of resource, and so on, until the section correction demand is met.

[0188] If the section correction demand > β*minimum pumped storage call-up amount: priority will be given to pumped storage, and then allocated in the order of thermal power, energy storage, and new energy until the section correction demand is met.

[0189] The collaborative control layer will send the generated section collaborative control information, namely the over-limit section, the reverse flag of the section correction demand, and the section correction demand borne by various resources, to the conventional AGC, energy storage AGC, and new energy AGC respectively.

[0190] Step 6: Conventional AGC and energy storage AGC calculate and generate the control target of the control object according to the set strategy based on the section collaborative control information and frequency modulation collaborative control information generated by the collaborative control layer, and send the control instructions to the pumped storage power station, thermal power plant, and energy storage power station respectively.

[0191] Conventional AGC and energy storage AGC perform corresponding processing according to the section collaborative control information generated by the collaborative control layer:

[0192] (1) Overload section, section forbidden upper flag: the upper limit of the control object under the section is updated to the current real-time output, and the upper adjustment instruction of the control object under the section is locked.

[0193] (2) The same direction flag for over-limit section and section correction requirement: the frequency regulation allocation priority of the control object under the section is raised to the highest level, and the section is adjusted while meeting the frequency regulation requirement.

[0194] (3) Over-limit sections, section correction demand reverse flag, and assumed section correction demand: Sort the sections according to their sensitivity to the control objects under the sections, and update the upper limit of the control objects in turn to the current real-time output minus one step, so as to achieve downward adjustment of the control objects until the assumed section correction demand is met.

[0195] Conventional AGC and energy storage AGC allocate the thermal power frequency regulation demand to each thermal power unit according to the frequency regulation allocation priority based on the frequency regulation coordinated control information generated by the coordinated control layer, and meet the control object limit constraints after processing (1) to (3) above.

[0196] Step 7: The new energy AGC calculates and generates the control target of the control object according to the section collaborative control information and peak-shaving collaborative control information generated by the collaborative control layer, and sends the control command to the new energy station according to the set strategy.

[0197] The new energy AGC processes the cross-section collaborative control information generated by the collaborative control layer:

[0198] (1) Overloaded section, section forbidden upper flag: the upper limit of the control object under the section is updated to the current real-time output, and the upper adjustment instruction of the control object under the overloaded section is locked.

[0199] (2) Over-limit sections and correction requirements for over-limit sections: The controlled objects under the section are assigned a downward adjustment step in turn according to the peak-shaving priority of the new energy station until the correction requirements for over-limit sections are met.

[0200] The new energy AGC deducts the adjustment amount of (2) above from the new energy peak-shaving demand based on the peak-shaving collaborative control information generated by the collaborative control layer, and deducts the control object responsible for over-limit correction, and then allocates a downward adjustment step in sequence according to the peak-shaving priority until the new energy peak-shaving demand is met.

[0201] Among them, the priority sorting factors support the following two types:

[0202] a) Load rate;

[0203] b) Deviation between actual output and planned value.
