Description

Technical Field

[0001] The present invention relates to the technical field of power system planning, and in particular to an energy management system and method for a photovoltaic storage charging and discharging station suitable for emergency response. Background Art

[0002] With the rapid development and widespread popularity of electric vehicles in my country, the distribution of supporting charging stations has gradually expanded from urban load centers to rural areas and even remote areas.

[0003] Conventional charging stations are powered solely by a dedicated power line from the power company and provide charging services to users (electric vehicles). If the power company is unable to supply power, the station cannot provide charging services. With the development of photovoltaic and energy storage technologies, photovoltaic and energy storage charging stations have emerged. These use photovoltaic and energy storage equipment to convert solar power into electricity and store it at the power station. These charging stations can provide charging services to users by either receiving power from a dedicated power line from the power company or by using the energy generated and stored by the photovoltaic and energy storage equipment within the power station. As a result, they are gradually gaining adoption and popularity.

[0004] Conventional solar-powered charging station energy management systems, under normal circumstances, provide simple charging services to regular users (electric vehicles) according to their application schedules, meeting their charging needs. However, when the area where the power station is located encounters an emergency (such as an earthquake, ice storm, or other natural disaster), on the one hand, the area may experience large-scale power outages, and emergency users such as important facilities, key livelihoods, emergency rescue, disaster relief, and grid repair will issue emergency power supply requests. On the other hand, the solar-powered charging station stores ample electricity, but because its energy management system can only support the station to provide simple charging services to regular users (electric vehicles) according to their application schedules, and lacks communication and interconnection with emergency management agencies, power companies, emergency users, and other power stations, it suffers from passive response, single principles, and simple functions. It is unable to proactively, prioritize, and intelligently utilize the emergency response capabilities of the solar-powered charging station, unable to meet the power supply needs of emergency users, resulting in idle and wasted emergency resources.

[0005] Prior art CN116131344A, a community electricity optimization management system based on an energy management platform, and CN111478334B, a smart grid utilizing a comprehensive social energy storage system, disclose methods for allocating electricity based on user demand and time-of-use electricity prices, vehicle reservation schedules, remaining battery capacity in electric vehicles, load power requirements, and grid power availability. In these prior art systems, power supply is based on user demand and time-of-use electricity prices, leaving no reasonable method for allocating electricity in emergencies. Summary of the Invention

[0006] In order to solve the above problems existing in the prior art, the present invention proposes an energy management system and method for a photovoltaic storage charging and discharging station suitable for emergency response.

[0007] The technical solutions of the present invention are as follows:

[0008] On the one hand, the present invention proposes an energy management system for a photovoltaic storage charging and discharging station suitable for emergency response, comprising a photovoltaic power generation and energy storage module, a multi-party communication interconnection module, and an emergency response module; the emergency response module comprises an active response module, a priority response module, and an intelligent response module; the multi-party communication interconnection module and the emergency response module are both connected to the photovoltaic power generation and energy storage module;

[0009] The photovoltaic power generation and energy storage module is used in a photovoltaic charging and discharging station to collect and store electrical energy;

[0010] The multi-party communication interconnection module is used to establish communication connections between the photovoltaic storage charging and discharging station and various power management units and emergency users;

[0011] The active response module is used to report the power information of the photovoltaic charging and discharging station to the power management units in real time in an emergency, and to receive emergency instructions from the power management units in real time; the power information includes the location of the photovoltaic charging and discharging station, the reserve power, the available status of the equipment in the station, and the communication and networking capabilities of the station with the outside world;

[0012] The priority response module is used to divide the emergency users into different levels according to their types in an emergency, and to prioritize the emergency users included in each level;

[0013] In an emergency, the intelligent response module calculates the optimal power distribution plan based on the reserve power of each photovoltaic storage charging and discharging station and the power demand, priority order and distance of each emergency user to the target power station.

[0014] As a preferred implementation manner, the electricity management units include power companies and emergency management agencies.

[0015] As a preferred embodiment, the emergency instructions of the electricity management agency include the amount of electricity that the photovoltaic storage charging and discharging station needs to retain, the equipment that needs to be put into use, and the objects to be supplied with emergency power.

[0016] As a preferred embodiment, the steps of calculating the optimal power distribution plan based on the reserve power of each photovoltaic storage charging and discharging station and the power demand and priority order of each emergency user are specifically as follows:

[0017] The weight coefficient K(i) of the total electric energy allocation of each level of emergency users is determined according to the actual situation, and the weight coefficient K(i) must meet the constraints:

[0018]

[0019] Where n is the total number of levels;

[0020] When the reserve power of the target power station is greater than or equal to the total power demand of emergency users at all levels, power will be supplied in order of priority based on the power demand of each emergency user. The specific allocation formula is as follows:

[0021] g(i,j)=f(i,j)

[0022] Where i is the level to which the emergency user belongs, j is the order of the emergency users within each level; g(i,j) is the actual amount of electricity allocated to the j-th emergency user in the i-th level; f(i,j) is the electricity demand proposed by the j-th emergency user in the i-th level;

[0023] When the target power station's reserve power is less than the total power demand of emergency users at all levels, and the total power demand proposed by the first-level emergency users is less than the allocated power calculated based on the weights, the allocation strategy for emergency users at all levels is as follows:

[0024]

[0025] Where Qz is the reserve power of the target power station.

[0026] When the target power station's reserve power is less than the total power demand of emergency users at all levels, and the total power demand proposed by the first-level emergency users is greater than the allocated power calculated based on the weights, the allocation strategy for emergency users at all levels is as follows:

[0027] g(i)=Qz×K(i)

[0028] Where Qz is the reserve power of the target power station, and K(i) is the power allocation weight coefficient of emergency users at each level.

[0029] As a preferred implementation, the distance between each emergency user and the target power station is used to further constrain the optimal allocation plan. The specific constraints are:

[0030] The actual amount of electricity g(i,j) allocated to each sequential emergency user in each level must meet the following constraints:

[0031]

[0032] Where T(i,j) is the distance coefficient between the jth emergency user at the i-th level and the power station;

[0033] The distance coefficient must meet the constraints:

[0034]

[0035] Where S(i,j) is the distance between the jth emergency user at the i-th level and the power station.

[0036] On the other hand, the present invention proposes an energy management method for a photovoltaic storage charging and discharging station suitable for emergency response, which specifically includes the following steps:

[0037] Photovoltaic power generation and energy storage modules are used in photovoltaic charging and discharging stations to collect and store electricity;

[0038] The solar storage charging and discharging station is connected to the power management units and emergency users;

[0039] In an emergency, the system reports the power information of the photovoltaic charging and discharging station to the power management units in real time, and receives emergency instructions from the power management units in real time. The power information includes the location of the photovoltaic charging and discharging station, the reserve power, the availability of the equipment in the station, and the communication and networking capabilities of the station with the outside world.

[0040] In an emergency, the emergency users are divided into different levels according to their types, and the emergency users included in each level are prioritized;

[0041] In an emergency, the optimal power distribution plan is calculated based on the reserve power of each photovoltaic storage charging and discharging station, as well as the power demand, priority order and distance of each emergency user to the target power station.

[0042] As a preferred implementation manner, the electricity management units include power companies and emergency management agencies.

[0043] As a preferred embodiment, the emergency instructions of the electricity management agency include the amount of electricity that the photovoltaic storage charging and discharging station needs to retain, the equipment that needs to be put into use, and the objects to be supplied with emergency power.

[0044] As a preferred embodiment, the steps of calculating the optimal power distribution plan based on the reserve power of each photovoltaic storage charging and discharging station and the power demand and priority order of each emergency user are specifically as follows:

[0045] The weight coefficient K(i) of the total electric energy allocation of each level of emergency users is determined according to the actual situation, and the weight coefficient K(i) must meet the constraints:

[0046]

[0047] Where n is the total number of levels;

[0048] When the reserve power of the target power station is greater than or equal to the total power demand of emergency users at all levels, power will be supplied in order of priority based on the power demand of each emergency user. The specific allocation formula is as follows:

[0049] g(i,j)=f(i,j)

[0050] Where i is the level to which the emergency user belongs, j is the order of the emergency users within each level; g(i,j) is the actual amount of electricity allocated to the j-th emergency user in the i-th level; f(i,j) is the electricity demand proposed by the j-th emergency user in the i-th level;

[0051] When the target power station's reserve power is less than the total power demand of emergency users at all levels, and the total power demand proposed by the first-level emergency users is less than the allocated power calculated based on the weights, the allocation strategy for emergency users at all levels is as follows:

[0052]

[0053] Where Qz is the reserve power of the target power station.

[0054] When the target power station's reserve power is less than the total power demand of emergency users at all levels, and the total power demand proposed by the first-level emergency users is greater than the allocated power calculated based on the weights, the allocation strategy for emergency users at all levels is as follows:

[0055] g(i)=Qz×K(i)

[0056] Where Qz is the reserve power of the target power station, and K(i) is the power allocation weight coefficient of emergency users at each level.

[0057] As a preferred implementation, the distance between each emergency user and the target power station is used to further constrain the optimal allocation plan. The specific constraints are:

[0058] The actual amount of electricity g(i,j) allocated to each sequential emergency user in each level must meet the following constraints:

[0059]

[0060] Where T(i,j) is the distance coefficient between the jth emergency user at the i-th level and the power station;

[0061] The distance coefficient must meet the constraints:

[0062]

[0063] Where S(i,j) is the distance between the jth emergency user at the i-th level and the power station.

[0064] The present invention has the following beneficial effects:

[0065] 1. The present invention establishes connections with various power management units and emergency power users through a multi-party communication interconnection module, maintains real-time connection and information sharing among multiple parties, and can respond quickly in emergency situations.

[0066] 2. The active response module in the present invention forms a communication interconnection with the emergency management agency, actively summarizes and reports the emergency response capability information of the power station to the emergency management agency, and receives and executes the instructions of the emergency management agency, thereby actively providing the emergency management agency with more emergency response measures to choose from.

[0067] 3. The priority response module in the present invention ensures that the power station stores electrical energy and gives priority to meeting the emergency power supply needs of emergency users, thereby giving priority to the emergency response capabilities of the power station and avoiding providing charging services only according to the timing proposed by demand.

[0068] 4. The intelligent response module in the present invention forms a communication interconnection with other charging and discharging stations, comprehensively considers and formulates a scientific and reasonable emergency response strategy to achieve a reasonable match between emergency response capabilities and the emergency needs of various users.

[0076] Example 1:

[0077] See also Figure 1 A photovoltaic charging and discharging station energy management system suitable for emergency response includes a photovoltaic power generation and energy storage module, a multi-party communication interconnection module, and an emergency response module; the emergency response module includes an active response module, a priority response module, and an intelligent response module; the multi-party communication interconnection module and the emergency response module are both connected to the photovoltaic power generation and energy storage module;

[0078] The photovoltaic power generation and energy storage module is used in a photovoltaic charging and discharging station to collect and store electrical energy;

[0079] The multi-party communication interconnection module is used to establish communication connections between the photovoltaic storage charging and discharging station and various power management units and emergency users;

[0080] The active response module is used to report the power information of the photovoltaic charging and discharging station to the power management units in real time in an emergency, and to receive emergency instructions from the power management units in real time; the power information includes the location of the photovoltaic charging and discharging station, the reserve power, the available status of the equipment in the station, and the communication and networking capabilities of the station with the outside world;

[0081] The priority response module is used to divide the emergency users into different levels according to their types in an emergency, and to prioritize the emergency users included in each level;

[0082] In an emergency, the intelligent response module calculates the optimal power distribution plan based on the reserve power of each photovoltaic storage charging and discharging station and the power demand, priority order and distance of each emergency user to the target power station.

[0083] In this embodiment, it is assumed that there is one residential area, one hospital, one main power supply line, one emergency management agency, multiple electric vehicles, and two photovoltaic storage charging and discharging stations in an area.

[0084] First, the photovoltaic power generation and energy storage modules of the two photovoltaic storage charging and discharging stations are arranged to carry out photovoltaic power generation and energy storage through the photovoltaic and energy storage equipment of the power station.

[0085] Secondly, the multi-party communication interconnection modules of the two photovoltaic storage charging and discharging stations establish communication interconnection with emergency management agencies, power companies, emergency users and other photovoltaic storage charging and discharging stations through various means.

[0086] Under normal circumstances, if Figure 2 As shown, the photovoltaic power generation and energy storage modules of the photovoltaic charging and discharging station respond to the charging needs of conventional users (such as electric vehicles), including: relying entirely on the stored electricity in the power station to charge users, applying for the power company to supplement the power supply to the power station before charging users, and rejecting users' charging needs due to insufficient power or other reasons.

[0087] When an emergency situation requires an emergency response, such as an earthquake that collapses a trunk line in an area, causing a total power outage in the area, the solar-storage charging station uses the emergency response module to enable the station to proactively, prioritize, and intelligently utilize its emergency response capabilities, including:

[0088] Active response module: The energy management system of the photovoltaic charging and discharging station receives notifications or signals from the emergency management agency about the occurrence of an emergency. The system actively summarizes and reports the emergency response capability information of the power station to the emergency management agency, such as: the location of the power station, the reserve power, the available status of the equipment in the station, and other emergency functions of the power station (such as communication and networking capabilities with the outside world); receives and executes instructions from the emergency management agency (for example: the power that the power station needs to retain, available equipment, and objects to be powered by emergency power, etc.).

[0089] Priority response module: When an emergency occurs and an emergency response is required, the system suspends charging services for regular users and gives priority to responding to emergency power supply needs submitted to the power station by power companies or emergency users, such as emergency power supply for important facilities (emergency management agencies, important hospitals, etc.), key livelihood (nighttime lighting, logistics power supply, etc.), rescue (transportation, water conservancy, etc.), disaster relief (personnel, property, etc.) and power grid repair.

[0090] Intelligent response module: When an emergency occurs and an emergency response is required, the system enables intelligent interaction between the energy management systems of each photovoltaic storage charging and discharging station, comprehensively considers information such as the instructions of the emergency management agency, the emergency response capabilities of each power station, and the needs of various emergency users, and formulates scientific and reasonable emergency response strategies (such as the two photovoltaic storage charging and discharging stations responding to the types of emergency users, load scales and distribution ranges, etc.), to achieve a reasonable match between the emergency response capabilities of the two photovoltaic storage charging and discharging stations and the emergency needs of various users. For example: meet the emergency needs of more important users (such as emergency management agencies, important hospitals, etc.) as soon as possible, try to meet the emergency needs of more users, avoid power congestion and equipment idle conditions in different power stations at the same time, and avoid surplus power and power depletion conditions in different power stations at the same time.

[0091] As a preferred implementation of this embodiment, the electricity management units include power companies and emergency management agencies.

[0092] As a preferred implementation of this embodiment, the emergency instructions of the electricity management agency include the amount of electricity that the photovoltaic storage charging and discharging station needs to retain, the equipment that needs to be put into use, and the objects to be powered by emergency power.

[0093] As a preferred implementation of this embodiment, the steps of calculating the optimal power distribution plan based on the reserve power of each photovoltaic storage charging and discharging station and the power demand and priority order of each emergency user are specifically as follows:

[0094] The weight coefficient K(i) of the total electric energy allocation of each level of emergency users is determined according to the actual situation, and the weight coefficient K(i) must meet the constraints:

[0095]

[0096] Where n is the total number of levels;

[0097] When the reserve power of the target power station is greater than or equal to the total power demand of emergency users at all levels, power will be supplied in order of priority based on the power demand of each emergency user. The specific allocation formula is as follows:

[0098] g(i,j)=f(i,j)

[0099] Where i is the level to which the emergency user belongs, j is the order of the emergency users within each level; g(i,j) is the actual amount of electricity allocated to the j-th emergency user in the i-th level; f(i,j) is the electricity demand proposed by the j-th emergency user in the i-th level;

[0100] When the target power station's reserve power is less than the total power demand of emergency users at all levels, and the total power demand proposed by the first-level emergency users is less than the allocated power calculated based on the weights, the allocation strategy for emergency users at all levels is as follows:

[0101]

[0102] Where Qz is the reserve power of the target power station.

[0103] When the target power station's reserve power is less than the total power demand of emergency users at all levels, and the total power demand proposed by the first-level emergency users is greater than the allocated power calculated based on the weights, the allocation strategy for emergency users at all levels is as follows:

[0104] g(i)=Qz×K(i)

[0105] Where Qz is the reserve power of the target power station, and K(i) is the power allocation weight coefficient of emergency users at each level.

[0106] As a preferred implementation of this embodiment, the distance between each emergency user and the target power station is used to further constrain the optimal allocation plan. The specific constraints are:

[0108]

[0109] Where T(i,j) is the distance coefficient between the jth emergency user at the i-th level and the power station;

[0110] The distance coefficient must meet the constraints:

[0111]

[0112] Where S(i,j) is the distance between the jth emergency user at the i-th level and the power station.

[0113] In this example, it is assumed that there is one solar-to-storage charging and discharging station in a region with a stored power of 10,000 kWh. The emergency users, power demand, and distance from the station are shown in Table 1 below:

[0114] Table 1 Data of emergency users at each level, electricity demand, and distance from power stations

[0115]

[0116] According to the above calculation formula combined with actual data, the weight coefficient, distance coefficient and actual allocated power consumption of emergency users at each level are calculated as shown in Table 2 below.
