Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.

Because of the strong timeliness and space properties of energy required by people, in order to reasonably utilize the energy and improve the utilization rate of the energy, one energy form needs to be stored by one medium or equipment and then converted into another energy form, and the energy is released in a specific energy form based on future application. At present, the main way of generating green electric energy is to develop green energy sources such as photovoltaic, wind power and the like to replace fossil energy sources.

At present, the generation of green electric energy generally depends on photovoltaic, wind power, water potential and the like, but wind energy, solar energy and the like generally have the problems of strong intermittence and large fluctuation, which can cause unstable power grid, insufficient peak electricity consumption, too much electricity consumption and unstable voltage can cause damage to the electric power, so that the problem of 'wind abandoning and light abandoning' possibly occurs due to insufficient electricity consumption requirement or insufficient power grid acceptance, and the problem needs to be solved by relying on energy storage. The energy is converted into other forms of energy through physical or chemical means and is stored, the energy is converted into electric energy when needed and released, in short, the energy storage is similar to a large-scale 'charge pal', the electric energy is stored when the photovoltaic and wind energy are sufficient, and the stored electric power is released when needed.

Taking electrochemical energy storage as an example, the present disclosure provides an energy storage device, in which a group of chemical batteries are disposed, chemical elements in the batteries are mainly utilized as energy storage media, and the charge and discharge process is accompanied with chemical reaction or change of the energy storage media, which simply means that electric energy generated by wind energy and solar energy is stored in the chemical batteries, and when the use of external electric energy reaches a peak, the stored electric quantity is released for use, or is transferred to a place where the electric quantity is short for use.

The present energy storage (i.e. energy storage) application scenario is comparatively extensive, including aspects such as power generation side energy storage, electric wire netting side energy storage and power consumption side energy storage, and the kind of corresponding energy storage device includes:

(1) The large energy storage power station applied to the wind power and photovoltaic power station side can assist renewable energy sources to generate electricity to meet grid-connected requirements, and meanwhile, the utilization rate of the renewable energy sources is improved; the energy storage power station is used as a high-quality active/reactive power regulating power supply in a power supply side, so that the load matching of electric energy in time and space is realized, the capacity of absorbing renewable energy sources is enhanced, the instantaneous power change is reduced, the impact on a power grid is reduced, the problem of generating and absorbing new energy sources is solved, and the energy storage power station has great significance in the aspects of standby of a power grid system, relieving peak load power supply pressure and peak regulation and frequency modulation;

(2) The energy storage container applied to the power grid side has the functions of mainly peak regulation, frequency modulation and power grid blocking and peak regulation relieving, and can realize peak clipping and valley filling of the power consumption load, namely the energy storage battery is charged when the power consumption load is low, and the stored electric quantity is released in the peak period of the power consumption load, so that the balance between power production and power consumption is realized;

(3) The small energy storage cabinet applied to the electricity utilization side has the main functions of spontaneous electricity utilization, peak Gu Jiacha arbitrage, capacity cost management and power supply reliability improvement. According to the different application scenes, the electricity-side energy storage can be divided into an industrial and commercial energy storage cabinet, a household energy storage device, an energy storage charging pile and the like, and is generally matched with the distributed photovoltaic. The energy storage can be used by industrial and commercial users for valley peak price difference arbitrage and capacity cost management. In the electric power market implementing peak-valley electricity price, the energy storage system is charged when the electricity price is low, and the energy storage system is discharged when the electricity price is high, so that peak-valley electricity price difference arbitrage is realized, and the electricity cost is reduced. In addition, the energy storage system is suitable for two industrial enterprises with electricity price, can store energy when electricity is used in low valley and discharge the energy when the electricity is used in peak load, so that peak power and the declared maximum demand are reduced, and the purpose of reducing the capacity electricity fee is achieved. The household photovoltaic distribution and storage can improve the spontaneous self-use level of the electric power. Due to high electricity prices and poor power supply stability, the photovoltaic installation requirements of users are pulled. Considering that the photovoltaic power generation is performed in daytime, and the load of a user is generally higher at night, the photovoltaic power can be better utilized through configuration of energy storage, the spontaneous self-use level is improved, and meanwhile the power consumption cost is reduced. In addition, the fields of communication base stations, data centers and the like need to be configured with energy storage for standby power.

The embodiments of the present disclosure are not limited in this regard.

In the related art, when an auxiliary energy storage device is newly added to an energy storage system, generally, most of EMS adds one device to the newly added auxiliary energy storage device from a data layer to connect with one device, and there is no one-to-one mapping of attributes, services and events between the auxiliary energy storage device added by the EMS and a real device, so that the influence on the EMS of a single site is not obvious due to less mapping of the auxiliary energy storage device and a communication protocol, however, under the condition of multiple sites, the technical problems of high maintenance difficulty and large expansion difficulty exist.

When the number of auxiliary energy storage devices is large, management, interaction, expansion and the like between the devices become extremely difficult, and the following mainly appear:

1. the requirement on the management expertise between the devices is high, and different communication protocol devices are accessed, and each time, technicians are required to write codes to finish the process;

2. the compatibility is poor, when the requirement is changed or the communication protocol is changed, the adaptation change from the bottom communication protocol to the application service is needed to be realized, and the efficiency is low;

3. the expansibility is poor, and for the newly added function requirement, the slave device access layer is difficult to change, more manpower is required to be input, and the cost is high.

In order to solve at least part of the technical problems, the method comprises the steps of creating class objects according to class information by acquiring class information of a plurality of auxiliary energy storage devices, wherein one class object corresponds to at least one auxiliary energy storage device, selecting target class objects corresponding to each auxiliary energy storage device according to classes to which each auxiliary energy storage device belongs, configuring a point table for the target class objects, and constructing a device object model of each auxiliary energy storage device; creating a system object model, and binding the system object model with at least one equipment object model; performing equipment instantiation processing on at least one equipment object model to obtain instantiation equipment; the system object model is subjected to system instantiation processing to obtain configuration information of an instantiation system and an instantiation system, the configuration information of the instantiation system is sent to an EMU, and the EMU carries out data binding and collection according to the configuration information; on the other hand, the method and the device can realize equipment-level multiplexing and system-level multiplexing, can flexibly realize data acquisition and addition of channel protocols, greatly improve convenience of system management and have wide application range.

Under the system architecture described above, a device access method is provided in the embodiments of the present disclosure, and the method may be performed by any computer device having computing processing capabilities.

Fig. 4 shows a flowchart of a device access method provided in an embodiment of the present disclosure. As shown in fig. 4, the device access method provided in the embodiment of the present disclosure includes the following steps:

s402, obtaining class information of a plurality of auxiliary energy storage devices, and creating class objects according to the class information, wherein one class object corresponds to at least one auxiliary energy storage device.

In one embodiment, the categories of auxiliary energy storage devices may be divided by type, function, etc. of auxiliary energy storage devices.

It should be noted that the class of auxiliary energy storage devices may include one of gateway devices, gateway sub-devices, and direct connection devices. The gateway device is used for assisting in forwarding of a communication protocol, and belongs to a bridge for direct data interaction between a system and equipment, such as EMU equipment. The gateway sub-device is used for being responsible for uploading data, such as PCS, by the network manager. And the direct connection device is used for directly establishing connection with the EMS, such as a general control ammeter.

The class object is used for carrying common information of product types of the auxiliary energy storage devices and creating templates of the auxiliary energy storage devices. The common information carried by the category object may include one or more of attributes, events, and services in the category information. One class object may correspond to one auxiliary energy storage device, or may correspond to a plurality of auxiliary energy storage devices, which may be determined according to actual situations. According to the method and the device, the class object is constructed by extracting the common information of the product types of the auxiliary energy storage devices, so that the code writing requirement of technicians is reduced, and the compatibility and expansibility of device access are improved.

For example, for air-conditioning, products of different enterprises can be adopted, correspondingly, based on the air-conditioning provided by different enterprises, a class object can be corresponding, and for specific products, specific values of various information in class information can be the same or different.

S404, selecting target class objects corresponding to the auxiliary energy storage devices according to the classes of the auxiliary energy storage devices, configuring a point table for the target class objects, and constructing a device object model of the auxiliary energy storage devices.

The point table is used for configuring the memory address of the real equipment corresponding to each parameter of the class object, and the memory address represents the offset between the memory address and the memory starting address.

For the auxiliary energy storage devices of the same type, the memory addresses of the same information in the point table on different real devices can be the same or different, and the present disclosure is not limited specifically according to the actual situation.

The construction of the equipment model of the auxiliary energy storage equipment can be understood as a process of assigning various information of the target class object.

The values of the event information are respectively as follows: the data type dataType is BOOL, the identifier is inster abn, the name is insulation resistance exception, the product value ProducKey is a1TX, the event type eventType is info, the data range dataSpecs is 0 and normal, and 1 is exception.

It should be noted that, in an energy storage system, at least one auxiliary energy storage device of different types may be included, for accessing a plurality of auxiliary energy storage devices of the same type at the same time, on one hand, the present disclosure can conveniently and rapidly select a class object through a pre-constructed class object, and rapidly construct a device model for adding attribute values of each information of a target class object, on the other hand, the present disclosure may also construct a device model of one auxiliary energy storage device of the same type, and construct device models of other auxiliary energy storage devices of the same type in a multiplexing manner, thereby improving device access efficiency.

Creating the system thing model includes configuring system function information, such as determining a name of the system thing model, such as an a energy storage system.

It should be noted that, the number of at least one equipment object model in one system object model may be determined according to the number of real equipment, and the number of the same auxiliary energy storage equipment in the same enterprise may include at least one, and when the system object model includes a plurality of the same auxiliary energy storage equipment, the equipment object model may be called in a multiplexing manner, so as to quickly construct the system object model, improve the efficiency of converting and instantiating the equipment model, and facilitate equipment access and expansion.

In some embodiments, the system object model may be invoked in a multiplexed manner, and then modified and adjusted based on the system object model to obtain a desired system object model.

S408, performing equipment instantiation processing on at least one equipment object model to obtain instantiation equipment.

The equipment object model is subjected to equipment instantiation processing, and the equipment instantiation processing is used for establishing the corresponding relation between the equipment object model and real equipment.

S410, carrying out system instantiation processing on the system object model to obtain configuration information of the instantiation system and the instantiation system, and sending the configuration information of the instantiation system to an energy management system EMU so that the EMU can bind and collect data according to the configuration information.
