Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
Fig. 1 is a schematic flowchart of a method for controlling an energy storage system according to an embodiment of the present invention, where the method may be executed by a control device of the energy storage system, and the control device of the energy storage system may be implemented in a hardware and/or software manner. The control method of the energy storage system specifically comprises the following steps:
and S110, acquiring the operation information of the temperature control equipment.
The temperature control equipment can control the temperature of the energy storage system, so that the energy storage device can normally run at constant and proper temperature, the energy storage system can be matched with the dispatching of the power grid in time, and the operation and maintenance cost and loss of the power grid are reduced. Illustratively, the temperature control device may include an air conditioner, a liquid cooling unit, and a temperature and humidity sensor. The air conditioner can adjust the temperature of the environment around the energy storage system, so that the energy storage system can operate in the environment with proper temperature, namely, the energy storage system cannot maintain efficient work due to overheating or overcooling of the environment. The liquid cooling unit can be for energy storage system cooling, for example the heat that energy storage system produced in work (charging or discharging), can dispel the heat for energy storage system through the liquid cooling unit, prevents that energy storage system from being damaged because of the too high heat that work (charging or discharging) produced. The temperature and humidity sensor can monitor the temperature and humidity of the environment where the energy storage system is located and the temperature and humidity of the energy storage system in real time, so that the working mode (temperature rising, temperature lowering or stopping) of the air-conditioning and liquid-cooling unit can be adjusted at any time according to the temperature and humidity of the environment where the energy storage system is located and the temperature and humidity of the energy storage system, and the energy storage system can run under the appropriate temperature and humidity.
The operation information of the temperature control equipment refers to the specific state or the specific numerical value of each index of the temperature control equipment in operation.
For example, the operation information of the temperature control device may include: humidity value, temperature value, coil pipe anti-freezing state, exhaust temperature value, temperature sensing state, inner fan state, outer fan state, compressor state, electric heating state and emergency fan state.
Each operation information of the temperature control equipment can be obtained through real-time detection of the temperature control fault detection system, so that the overall operation state of the temperature control equipment can be comprehensively known.
And S120, determining the operation condition of the temperature control equipment according to the operation information.
Specifically, different operation conditions can be corresponded by different states or different numerical value ranges of each index of the temperature control equipment.
Optionally, the operating conditions include normal operation and fault operation.
The whole operation state (normal operation state or fault operation state) of the temperature control equipment can be comprehensively obtained according to the operation information of the temperature control equipment, so that the operation condition of the temperature control equipment is accurately determined. Specifically, if at least one piece of operation information of the temperature control device is in an abnormal range, it is indicated that the temperature control device has a fault, and the temperature control device is in a fault operation state, so that it can be determined that the operation condition of the temperature control device is fault operation. If all the operation information of the temperature control equipment is in the normal range, the temperature control equipment is not in fault, and the temperature control equipment is in the normal operation state, so that the operation condition of the temperature control equipment can be determined to be normal operation.
In addition, a plurality of other operating conditions may also be divided as needed, and this embodiment is not limited specifically, for example, when at least one piece of operation information of the temperature control device is located near the boundary of the normal range, the operating condition of the temperature control device may be a critical operating condition, and the like.
And S130, adjusting the protection parameters of the battery management system according to the operation working conditions, wherein different operation working conditions correspond to different protection parameters.
Specifically, when the temperature control device is not in fault, the energy storage system operates under the cooperative management protection of the temperature control device and the battery management system. When the temperature control equipment breaks down, the energy storage system runs under the management protection of the battery management system. If the protection parameters of the battery management system operation are not adjusted according to the current actual conditions under the condition that the temperature control equipment fails, the protection parameters of the battery management system operation cannot meet the requirements of the energy storage system, that is, the battery management system cannot protect and manage the energy storage system. Therefore, the protection parameters of the battery management system are adjusted according to the operation condition of the temperature control device, so that the requirement of the energy storage device is met.
In addition, different operating conditions correspond to different protection parameters. For example, when different operating conditions correspond to one protection parameter, the values of the protection parameters corresponding to the different operating conditions are different. When different operation conditions correspond to a plurality of protection parameters, the values of the protection parameters corresponding to the different operation conditions are at least one different.
It should be noted that, according to different operation conditions of the temperature control device, the protection parameters for adjusting the operation of the battery management system include a voltage threshold, a temperature threshold, a voltage rising speed, and a temperature rising speed, that is, when the temperature control device is changed from normal operation to fault operation, the protection parameters for adjusting the operation of the battery management system are different.
Optionally, the protection parameter includes a voltage threshold, a temperature threshold, a voltage rise speed, and a temperature rise speed.
Illustratively, when the temperature control device is operating normally, the protection parameters of the battery management system operation are adjusted to a first voltage threshold, a first temperature threshold, a first voltage rise speed threshold, and a first temperature rise speed threshold.
According to the embodiment of the invention, the overall operation state of the temperature control equipment is comprehensively obtained through the operation information of the temperature control equipment, so that the operation condition of the temperature control equipment is accurately determined, and the operation protection parameters of the battery management system are accurately adjusted according to the operation condition of the temperature control equipment, so as to meet the requirements of energy storage equipment. Therefore, the scheme can guarantee the operating efficiency of the energy storage system, improve the safety and stability of the energy storage system, and reduce the operation and maintenance cost and loss of a power grid.

For example, the temperature control device may be faulty due to over-high or under-low temperature, over-high or under-low humidity, etc. The unrecoverable fault refers to a fault which is generated by some parts of the temperature control equipment and cannot be recovered by self. For example, the temperature control device may be damaged due to damage to an inner fan, damage to an outer fan, or damage to a compressor of the temperature control device.
