Description

Technical Field

[0001] The present invention relates to the field of power systems, and in particular, to a thermal-electric regulation method, device, storage medium and electronic device based on a distribution area. Background Technique

[0002] At present, due to the inconsistent spatial and temporal characteristics of thermal-electric loads such as photovoltaic, energy storage, heat pump, ice storage air conditioner, etc. in each distribution area scenario (for example: 1) Temporal characteristics: Area 1 may have mostly residential users, and Area 2 may have mostly commercial users. Then during noon, the electricity consumption in Area 1 will be significantly less than that in Area 2. 2) Spatial characteristics: There may be more heat pump loads in Area 1, and there are basically no heat pump loads in Area 2. Then once the weather changes drastically, it is possible that the transformer in Area 1 will be in a high load factor condition for a long time, while Area 2 will be in a light load condition for a long time), the conflict of thermal-electric demands between power systems is becoming more and more intense. As the "core brain" of the thermal-electric conversion system, in related technologies, a large amount of research and application has been carried out on thermal-electric coordination strategies, mainly focusing on directions such as carbon trading mechanism, peak shaving and valley filling mechanism, new energy consumption mechanism, demand response, etc.

[0003] In related technologies, the problems existing in the commonly used thermal-electric coordination strategy solutions mainly lie in: they are mainly applied to power systems at the regional level and above, and it is difficult to obtain strategy control parameters (such as electricity price, real-time reference data of carbon trading, etc.) for small and micro park systems; and most of the existing strategy solutions have a single control target, lacking overall coordinated control strategy solutions at different scales, and the on-site application scenarios are limited.

[0035] Figure 1 is a flowchart of an optional electric heat regulation method based on a power distribution area according to an embodiment of the present invention, as Figure 1 shown, the method includes the following steps:

[0036] Step S101: Obtain the status characteristic data of the target substation area in the power system. The status characteristic data includes at least one of the following: the load rate of the target substation area, the load rate of adjacent substation areas, and the power data associated with the target substation area. The adjacent substation areas include the substation areas adjacent to the target substation area.

[0037] The above status characteristic data may include, but is not limited to: the substation area load rate Lr (of the present substation area (i.e., the target substation area) and adjacent substation areas) and the power data associated with the target substation area (for example, the new energy consumption rate Nr of the substation area (of the present substation area and adjacent substation areas), the power limit value P of the grid connection point of the substation area PCCres , the mutual assistance power limit value P between substation areas com , the operating state of the energy storage in the substation area (SOC BAT and the maximum charge and discharge power P BAT ), the comfortable human body operating power margin P of the heat pump load in the substation area margin ).

[0038] Step S102: Based on the status characteristic data, select multiple energy management strategies to obtain a selection result, and regulate the electrothermal energy of the power system based on the selection result. The multiple energy management strategies include: the inter-substation area regulation strategy, the intra-substation area regulation strategy, and the device-level regulation strategy. The inter-substation area regulation strategy is used to regulate the electrothermal energy of the target substation area based on the power router between the target substation area and adjacent substation areas. The intra-substation area regulation strategy is used to regulate the electrothermal energy within the target substation area based on the temperature of the equipment operation within the target substation area. The device-level regulation strategy is used to regulate the electrothermal energy of the target substation area based on the power of the energy storage device of the target substation area.

[0039] Figure 2 is a schematic diagram of the substation area structure in a power system according to an embodiment of the present invention. As Figure 2 shown, it includes: substation areas (AC substation areas (such as substation area 1 and substation area 2), DC substation areas), power routers. The AC substation areas may include energy storage, wind power (wind power generation), photovoltaic (photovoltaic power generation), loads (conventional loads, heat loads, and energy storage loads). The DC substation areas may include: energy storage, wind power, photovoltaic, charging piles, and other loads. AC represents alternating current, and DC represents direct current.

[0040] In this embodiment, the electrothermal collaborative energy management of the system can be completed by designing three scales: inter-substation area, intra-substation area, and device-level, including the following steps:

[0041] Step A: Judge the system operation state and select the applicable collaborative energy management strategy (corresponding to the energy management strategy);

[0042] Step B: When the operating conditions of the inter-substation area collaborative energy management strategy (corresponding to the inter-substation area regulation strategy) are met, enter the regulation of the device state between substation areas;

[0043] Step C: When the operating conditions of the collaborative energy management strategy within the substation area (corresponding to the regulation strategy within the substation area) are met, enter the device status regulation within the substation area;

[0044] Step D: When the operating conditions of the device-level collaborative energy management strategy (corresponding to the device-level regulation strategy) are met, enter the device status regulation at the device level.

[0045] Step A specifically includes the following steps:

[0046] Step A1: Calculate the system state characteristics for energy management strategy selection; the system state characteristics (corresponding to the state characteristic data) include: the substation area load rate Lr (of this substation area and adjacent substation areas), the new energy consumption rate Nr (of this substation area and adjacent substation areas), the power limit P at the grid connection point of the substation area PCCres , the mutual assistance power limit P between substation areas com , the operating state of the energy storage in the substation area (SOC BAT and the maximum charge and discharge power P BAT ), the comfort human body operating power margin P of the heat pump load in the substation area margin . The calculation methods of each characteristic quantity are as follows:

[0047] Substation area load rate Lr:

[0048]

[0049] Among them, P PCC represents the power value at the grid connection point of this substation area, a positive value indicates obtaining energy from the grid, and a negative value indicates feeding energy to the grid; P rate represents the rated capacity of the transformer at the grid connection point of this substation area.

[0050] Substation area new energy consumption rate Nr:

[0051]

[0052] Among them, P Ln represents the device n power of all non-energy storage and new energy devices in this substation area, P BATm represents the maximum charge and discharge power of the energy storage device m, and P NRi represents the power of the new energy device i (such as photovoltaic, wind power, etc.) in this substation area.

[0053] Power limit P at the grid connection point of the substation area PCCres (divided into the upstream power P PCCresUp (the limit of the upstream power at the grid connection point) and the downstream power P PCCresDown (the limit of the downstream power at the grid connection point):

[0054] P PCCres = k1 * P PCCresDown = min(Pdsp , P safe )

[0055] P PCCres = k2 * P PCCresUp = min(P dsp , P safe )

[0056] Among them, P dsp represents the upper and lower power scheduling settings of the power system or the aggregated control system for the grid connection point of the distribution area; P safe represents the power limit for the safe operation of the grid connection point of this distribution area; k1 and k2 represent the margin coefficients, and these values are used in the strategy to ensure the margin of the system operating state from the over-limit state.

[0057] The mutual assistance power limit P between distribution areas com :

[0058] P com = P route , (When two distribution areas are directly connected by an electric energy router)

[0059] Among them, P route represents the rating of the electric energy router connecting the two distribution areas.

[0060] The comfort human body operation power margin P of the heat pump load in the distribution area marginMax and P marginMin :

[0061] P marginMax = f(T max , T current , P current ) - P current

[0062] P marginMin = f(T min , T current , P current ) - P current

[0063] Among them, T current represents the current indoor temperature of the system where the heat pump is located; T max represents the highest indoor temperature that meets human comfort; T min represents the lowest indoor temperature that meets human comfort; P current represents the current power of the heat pump; f represents the electrothermal characteristics of the heat pump, that is, the output power of the heat pump when maintaining the indoor temperature T; P marginMax represents the difference between the operating power of the heat pump and the current power when the heat pump is set to the highest human comfort temperature; P marginMin represents the difference between the operating power of the heat pump and the current power when the heat pump is set to the lowest human comfort temperature.

[0064] Optionally, the power data includes: the grid connection point power, and the grid connection point power includes: at the current moment, the power of the target substation area at the grid connection point. Based on the state characteristic data, multiple energy management strategies are selected to obtain a selection result, including: comparing the grid connection point power with the grid connection point power limit value to obtain a comparison result; based on the comparison result, the load factor of the target substation area and the load factor of the adjacent substation area, multiple energy management strategies are selected to obtain a selection result.

[0065] Figure 3 It is a flowchart of an optional electric heat regulation process based on the substation area according to an embodiment of the present invention, as Figure 3 shown, including:

[0066] Step A2: Determine whether to input an energy management strategy according to the real-time power P PCC (corresponding to the grid connection point power, a positive value represents the downlink power, and a negative value represents the downlink power) and the system state characteristics.

[0067] When P PCC ≤P PCCresDown or P PCC ≥P PCCresUp , go to step A3 to select multiple energy management strategies based on the load factor of the target substation area and the load factor of the adjacent substation area;

[0068] When P PCC <P PCCresUp or P PCC >P PCCresDown , go to step A4 to select multiple energy management strategies to obtain a selection result.

[0069] According to the comparison result obtained by comparing the grid connection point power with the grid connection point power limit value, the load factor of the target substation area and the load factor of the adjacent substation area, multiple energy management strategies are selected, achieving the purpose of reasonably selecting energy management strategies when the power grid is in different states.

[0070] Optionally, the grid connection point power limit includes: the limit of the upstream power of the grid connection point and the limit of the downstream power of the grid connection point. The power data further includes: the target heat pump power, and the target heat pump power includes: the difference between the operating power of the heat pump in the target area at a preset temperature and the operating power of the heat pump at the current moment. Based on the comparison result, the load factor of the target area, and the load factor of the adjacent area, multiple energy management strategies are selected to obtain a selection result, including: when the comparison result indicates that the grid connection point power is less than or equal to the limit of the downstream power of the grid connection point, or when the comparison result indicates that the grid connection point power is greater than or equal to the limit of the upstream power of the grid connection point, the selection result is determined based on the absolute value of the difference between the load factor of the target area and the load factor of the adjacent area; when the comparison result indicates that the grid connection point power is less than the limit of the upstream power of the grid connection point, the selection result is determined as the inter-area regulation strategy; when the comparison result indicates that the grid connection point power is greater than the limit of the downstream power of the grid connection point, the selection result is determined based on the target heat pump power.

[0071] The above-mentioned power data further includes: the target heat pump power, and the target heat pump power includes: the difference between the operating power of the heat pump in the target area at a preset temperature and the operating power of the heat pump at the current moment. The above-mentioned preset temperature may include but is not limited to: the highest human comfort temperature, the lowest human comfort temperature, that is, the above-mentioned target heat pump power may include: the difference between the operating power of the heat pump when the set temperature of the heat pump is the highest human comfort temperature and the current power (denoted as P marginMax ) and the difference between the operating power of the heat pump when the set temperature of the heat pump is the lowest human comfort temperature and the current power (denoted as P marginMin ).

[0072] For example, when P PCC ≤P PCCresDown or P PCC ≥P PCCresUp (that is, when the comparison result indicates that the grid connection point power is less than or equal to the limit of the downstream power of the grid connection point, or when the comparison result indicates that the grid connection point power is greater than or equal to the limit of the upstream power of the grid connection point, the selection result is determined based on the absolute value of the difference between the load factor of the target area and the load factor of the adjacent area), go to step A3, calculate the absolute value of the difference between the load factor of the target area and the load factor of the adjacent area, that is, |Lr1 - Lr2|, where Lr1 represents the load factor of the target area and Lr2 represents the load factor of the adjacent area, and determine whether |Lr1 - Lr2| is greater than the preset load factor difference threshold (k), and determine the selection result according to the judgment result.

[0073] When P PCC <P PCCresUp or P PCC >P PCCresDown When, go to step A4, when PPCC <P PCCresUp When (that is, when the comparison result indicates that the power at the grid connection point is less than the upper limit of the upstream power at the grid connection point), it means that the new energy output is excessive and there is a phenomenon of power being sent back to the power grid, and it enters step B2 of the inter-station area regulation strategy. When P PCC >P PCCresDown When, it means that the heat load is out of limit and it is necessary to implement the energy management strategy and enter step A5.

[0074] Step A5: The following judgments can be made:

[0075] When min(P marginMax , P marginMin ) < 0 and |min(P marginMax , P marginMin )| > |P PCC - P PCCresDown |, the device-level energy management strategy (corresponding to the device-level regulation strategy) can be implemented. If, after implementing the device-level energy management strategy, P PCC ≥P PCCresDown When, the in-station area energy management strategy (corresponding to the in-station area regulation strategy) can be implemented, achieving the purpose of multi-scale electro-thermal collaborative energy management.

[0076] Optionally, based on the absolute value of the difference between the load factor of the target station area and the load factor of the adjacent station area, the selection result is determined, including: judging whether the absolute value of the difference between the load factor of the target station area and the load factor of the adjacent station area is greater than the preset load factor difference threshold to obtain the judgment result; when the judgment result indicates that the absolute value of the difference between the load factor of the target station area and the load factor of the adjacent station area is greater than the preset load factor difference threshold, determining the selection result as the inter-station area regulation strategy; when the judgment result indicates that the absolute value of the difference between the load factor of the target station area and the load factor of the adjacent station area is not greater than the preset load factor difference threshold, determining the selection result as not adopting multiple energy management strategies.

[0077] For example, in step A3, when |Lr1 - Lr2| > k, the inter-station area energy management strategy is implemented and it enters step B1, where k represents the load factor difference threshold between this station area and the adjacent station area (corresponding to the preset load factor difference threshold); when the above conditions are not all met, the energy management strategy is not implemented.

[0078] Step A4: When P PCC <P PCCresUp When, it means that the new energy output is excessive and there is a phenomenon of power being sent back to the power grid, and it enters step B2 of the inter-station area regulation strategy; when P PCC ≥P PCCresDown When, it means that the heat load is out of limit and it is necessary to implement the energy management strategy and enter step A5.

[0079] Step A5: Make the following judgments:

[0080] When min(P marginMax , P marginMin ) < 0 and |min(P marginMax , P marginMin )| > |P PCC - P PCCresDown |, implement the device-level energy management strategy (corresponding to the device-level regulation strategy), and enter Step D. If, after entering Step D, P PCC ≥P PCCresDown still holds, the in-region energy management strategy (corresponding to the in-region regulation strategy) can be implemented, and enter Step C;

[0081] After completing the energy management regulation in Steps D and C, if P PCC ≥P PCCresDown still holds, the inter-region energy management strategy can be implemented, enter Step B3, and the purpose of multi-scale electro-thermal collaborative energy management is achieved.

[0082] Optionally, based on the selection result, regulating the electro-thermal of the power system further includes: when the selection result is the inter-region regulation strategy and the absolute value of the difference between the load factor of the target region and the load factor of the adjacent region of the target region is greater than the preset load factor difference threshold, regulating the operating power of the power router based on the rated power of the target region, the rated power of the adjacent region, the grid connection point power, and the power of the adjacent region at the grid connection point to regulate the electro-thermal of the power system; when the selection result is the inter-region regulation strategy and the grid connection point power is less than the upper limit value of the upstream power of the grid connection point, regulating the operating power of the power router based on the power of all devices in the target region, the rated power of the power router, and the power consumption of the energy-consuming devices in the adjacent region to regulate the electro-thermal of the power system; when the selection result is the inter-region regulation strategy and after regulating the electro-thermal of the power system by using the device-level regulation strategy and the in-region regulation strategy, and the grid connection point power is greater than the lower limit value of the downstream power of the grid connection point, regulating the operating power of the power router based on the target heat pump power to regulate the electro-thermal of the power system.

[0083] For example, Step B (inter-region regulation strategy) specifically includes the following steps (i.e., Step B1, Step B2, and Step B3):

[0084] Step B1: By setting the operating power command of the power router, complete the power flow distribution adjustment between two regions, ensure that the load factors of the two regions tend to be the same, and solve the load balancing problem between adjacent regions. The detailed steps include:

[0085] (1) Collect the power values of the point of common coupling (PCC) of this substation area (corresponding to the target substation area) and the adjacent substation area, which are P0 (corresponding to the power at the point of common coupling) and P1 (corresponding to the power of the adjacent substation area at the point of common coupling), respectively;

[0086] (2) Assume that the rated powers of this substation area and the adjacent substation area are P3 (corresponding to the rated power of the target substation area) and P4 (corresponding to the rated power of the adjacent substation area), respectively, and calculate the transformer load rates of the two substation areas: cof1 = abs(P0) / P3, cof2 = abs(P1) / P4;

[0087] (3) The strategy will set the operating powers P5 and P6 of the power router connecting the two substation areas (i.e., regulate the power router), where P5 = P0 - (P0 + P1) * P3 / (P3 + P4), P6 = P0 - (P0 + P1) * P3 / (P3 + P4).

[0088] Step B2: Starting from maximizing the consumption of green electricity, fully considering the power limit modes of the energy-consuming equipment in the adjacent substation area and its own photovoltaic power, the problem of green electricity consumption can be better solved by setting the operating power instruction of the power router; the detailed steps include:

[0089] (1) Obtain the total real-time power P of all equipment (except photovoltaic) in this substation area cal and the real-time power generation power P0 of the photovoltaic;

[0090] (2) Obtain the remaining green electricity power P res = |P0 - P cal |;

[0091] (3) Obtain the power consumption P2 of the energy-consuming equipment in the adjacent substation area;

[0092] (4) When P res ≤ min(P com , P2), then the strategy sets the operating power of the power router connecting the two substation areas to P2;

[0093] (5) When P res > min(P com , P2), then the strategy sets the operating power of the power router connecting the two substation areas to min(P com , P2), and at the same time sets the photovoltaic in this substation area to the power limit mode, and the power value is set to: P res - min(P com , P2).

[0094] Step B3: For the situation where the power at the grid connection point still cannot meet the limit requirements after using both device-level and substation area control measures simultaneously (i.e., when the selected result is the substation area control strategy, and device-level control strategy and substation area control strategy have been adopted to control the electrothermal of the power system), the detailed steps include:

[0095] Obtain the power value to be regulated:

[0096] P last = |P PCC - P PCCresDown | - |min(P marginMax , P marginMin )| - P batSet ;

[0097] When P com > P last , the strategy sets the operating power of the power router connecting the two substations to P last ;

[0098] When P com ≤P last , the strategy sets the operating power of the power router connecting the two substations to P com .

[0099] According to different situations, different substation area energy control strategies are selected, achieving the purpose of multi-scale electrothermal collaborative energy management.

[0100] Optionally, based on the selected result, controlling the electrothermal of the power system further includes: when the selected result is the substation area control strategy, controlling the temperature of the equipment operation in the target substation area based on the difference between the power at the grid connection point and the limit value of the downstream power at the grid connection point, so as to control the electrothermal of the power system.

[0101] In this embodiment, when the system operating state meets the operating conditions of the substation area collaborative energy management strategy, the substation area equipment state control (corresponding to the substation area control strategy) can be entered, which specifically includes the following steps:

[0102] Step C1: Calculate the operating set temperature T according to P PCC - P PCCresDown = f(T max , T, P current ); where f is the operating characteristic function of the heat pump, achieving the purpose of substation area energy management.

[0103] Optionally, based on the selection result, the electrothermal energy of the power system is regulated, and it further includes: when the selection result is the device-level regulation strategy, obtaining the operation status data of the energy storage device in the target substation area, and based on the operation status data of the energy storage device, setting the operation power of the energy storage device to regulate the electrothermal energy of the power system.

[0104] When the operating state of the power system meets the operating conditions of the device-level collaborative energy management strategy, enter the device-level device status regulation (corresponding to the device-level regulation strategy), which specifically includes the following steps:

[0105] Step D1, when SOC ≤ SOC L , the power of the energy storage device is set to 0, where SOC represents the remaining power of the energy storage device, and SOC L represents the minimum discharge depth of the energy storage;

[0106] Step D2, obtain the power P batPro that the energy storage device should provide = |P PCC -P PCCresDown |-|min(P marginMax , P marginMin )(corresponding to the operating state of the energy storage device);

[0107] Step D3, when P batPro < P BAT and SOC > SOC L , the power P batSet of the energy storage device is set to P batPro ;

[0108] Step D4, when P batPro ≥ P BAT and SOC > SOC L , the power P batSet of the energy storage device is set to P BAT (the maximum charge and discharge power of the energy storage device).

[0109] The electrothermal regulation method based on the substation area provided in this embodiment is a multi-scale control strategy, which can make full use of the self-regulation performance of the device, the energy complementarity of the devices in the substation area, and the energy mutual assistance ability between substation areas, overall consider multiple control objectives, and enhance the scenario applicability of the electrothermal system control.
