Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, the present disclosure is further described in detail below with reference to specific embodiments.
It is to be noted that unless otherwise defined, technical or scientific terms used in one or more embodiments of the present specification should have the ordinary meaning as understood by those of ordinary skill in the art to which this disclosure belongs. The use of "first," "second," and similar terms in one or more embodiments of the specification is not intended to indicate any order, quantity, or importance, but rather is used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
Aiming at the problem of seasonal or sudden load increase, an energy storage device can be added at a transformer user side of a transformer in a transformer area to solve the problem by adopting a scheme of peak clipping and valley filling, namely, under the condition of keeping the original transformer capacity unchanged, the energy storage device is charged at the electricity consumption valley period, and the energy storage device is matched with the transformer to supply power for the load additionally at the electricity consumption peak period. So as to reduce the cost and the construction workload of replacing the transformer.
To solve the problem by using the energy storage device, the energy storage battery has to have a large enough capacity and a battery with good charging and discharging performance, so the main factor restricting the implementation of the scheme is the manufacturing cost of the battery, and the retired power storage performance is a lithium battery with excellent performance, the price of the lithium battery is only one tenth of the price of a new lithium battery, and the energy storage device is very suitable for being applied to a platform energy storage system and used as an energy storage battery for 'peak clipping and valley filling'.
Technically, the new energy storage battery and the echelon utilization battery have no essential difference technically, but the energy storage system is applied to a platform area due to large investment, particularly, the investment of the battery accounts for more than 60% of the whole energy storage device, the price is high, the material cost of the echelon battery is reduced compared with that of the new battery, but the echelon battery is required to be recombined for adapting to the energy storage device, namely, an original vehicle-mounted battery pack is disassembled into a battery module, and then the BMS is newly assembled, so that the recombination cost of the echelon battery is invisibly increased, and the benefit of the energy storage system is also influenced.
One or more embodiments of the present specification provide a station integrated energy storage device based on a new energy vehicle retired battery, including a retired battery system 1, a Power Conversion System (PCS)2, a first power monitoring instrument 4, an Energy Management System (EMS)3, and a communication protocol converter 5, where the retired battery system 1 includes a battery body and a Battery Management System (BMS), for example, the retired battery system 1 is a vehicle-mounted battery system, i.e., a whole battery pack, that is retired on the new energy vehicle and includes the BMS;
the electric energy conversion system 2 is respectively connected with the decommissioned battery system 1 and the transformer area alternating current bus, and is used for controlling the charging and discharging processes of the decommissioned battery system 1 and performing alternating current-direct current conversion between the decommissioned battery system 1 and the transformer area alternating current bus;
the first electric quantity monitoring instrument 4 is connected to an electric energy interface for lifting an alternating current bus and is used for collecting operation data of the alternating current bus of the transformer area, for example, the first electric quantity monitoring instrument is connected to a wire outlet end of a transformer of the transformer area, and the main purpose is to monitor the load change condition in real time and judge whether the transformer of the transformer area is in a load electricity utilization valley period or an overload working period.
The energy management system 3 sends a regulation signal to the electric energy conversion system 2 according to the operation data of the transformer area alternating current bus, the monitoring data of the battery management system and a preset control strategy, so as to realize the regulation of the electric energy size and the flow direction between the electric energy conversion system 2 and the retired battery system 1, for example, the charging and discharging strategy can adopt: in the load electricity consumption low-valley period, the electric energy conversion system 2 is started to supply power to the decommissioned battery system 1, when the electricity consumption load of the transformer area is monitored to exceed the capacity of the transformer, the electric energy conversion system 2 is started to discharge electricity to the transformer area alternating current bus, the discharge power is controlled to enable the electric energy of the transformer area to be reduced to be below the rated capacity, charging can be carried out in the low-valley electricity price at night and discharging is carried out in the peak-valley electricity price in the daytime, and therefore electricity charges are saved by utilizing the peak-valley price difference.
The communication protocol converter 5(CM) is connected to the battery management system, the electric energy conversion system 2, and the energy management system 3, respectively, and is used for performing bus conversion and protocol conversion among the battery management system, the electric energy conversion system 2, and the energy management system 3, because the vehicle industry uses a CAN field bus for main information transfer due to historical reasons and industry reasons, and the power system uses an RS485 field bus or a LAN (TCP/IP) communication protocol, and the information transfer mode and the communication protocol of the two are incompatible, which causes that the two cannot be directly interconnected, and if a battery pack is directly used for the electric energy storage system, the problem of communication incompatibility must be solved. For example, the CM has three interfaces, three information streams are respectively communicated with the BMS, the PCS and the EMS, the CM is used as a node on a CAN bus in the communication with the BMS, the ID number of an original Vehicle Controller Unit (VCU) appears to simulate the VCU, but the power battery information is collected in real time and other original vehicle-mounted information is ignored, and the collected battery information is rearranged and stored in the CM. Meanwhile, control commands of the EMS and the PCS are converted into CAN protocols, and the VCU is simulated to send action commands (mainly protection commands) to the BMS.
In the communication between the CM and the PCS, according to the MODBUS-RTU protocol which is commonly used in the industrial process, the CM is used as a slave of the PCS, and is subject to the dispatching of the PCS, or transmits information related to a battery pack, or executes a protection instruction from the PCS.
The communication with CM and EMS is the same as PCS, except that the communication interface of PCS is RS-485, the protocol of both parties is MODBUS-RTU, and the communication interface of CM and EMS is LAN, the protocol of both parties is MODBUS-TCP.
The CM is equivalent to a 'switch' which continuously performs information exchange among three devices, namely BMS, PCS and EMS in real time.
