Description

Technical Field

[0001] The present invention belongs to the technical field of user-side energy storage control, and in particular relates to a user-side energy storage distributed control method and system. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] With the development of the power system and the widespread access to new energy sources, the role of user-side energy storage in the power system has become increasingly prominent. User-side energy storage systems, especially electrochemical energy storage systems, have been rapidly developed and widely used in recent years due to their technological advances and cost reductions. User-side energy storage systems can absorb, store and output the electric energy of power users, smooth the output of new energy sources, improve the peak load shaving capacity of the power system, and strongly support the new power system with new energy as the main body.

[0004] There are certain limitations in the regulation of user-side energy storage in the existing technology. Compared with centralized energy storage on the source side and the grid side, user-side energy storage is more dispersed, with smaller single-unit capacity and larger number, making it difficult to carry out centralized regulation. In addition, user-side energy storage belongs to different property owners, and the centralized direct control mode is more difficult for users to accept than the distributed control mode. The distributed control method has the characteristics of strong control robustness and decentralization, and is more suitable for coordinated control of a large number of distributed energy storage. In terms of the SOC consistency regulation method of user-side energy storage, it is mostly used in isolated island scenarios, where the energy storage converter adopts droop control. The virtual power plant requires that the aggregated resources are always in a grid-connected state. In the absence of a droop control loop to achieve preliminary power consistency, the aggregator also faces the problem of achieving SOC balance by aggregating user-side energy storage. Summary of the invention

[0005] To solve the above problems, the present invention proposes a user-side energy storage distributed control method and system, which considers the user-side energy storage distributed control of SOC balance and power balance, and realizes switching between two different control modes of output power consistency control and SOC consistency control through a cluster control algorithm, so as to adapt to different power grid control requirements and enhance the safety and reliability of power grid operation.

[0045] Embodiment 1

[0046] Embodiment 1 of the present invention introduces a distributed control method for energy storage at a user side.

[0047] like Figure 1 A user-side energy storage distributed control method is shown, comprising:

[0048] Obtain the output power of the energy storage on the user side;

[0049] According to the obtained output power, the control mode of the user-side energy storage is selected to complete the distributed control of the user-side energy storage;

[0050] Among them, the control modes of user-side energy storage include power balance consistency control and SOC balance consistency control. In the process of selecting the control mode of user-side energy storage, the switching function of SOC balance and power balance control modes is determined based on the side energy storage cluster regulation method, and the control mode of user-side energy storage is selected according to the control mode switching coefficient in the determined switching function.

[0051] In this embodiment, the distributed control logic of user-side energy storage considering power balancing is as follows: when demand-side entities such as virtual power plants aggregate and regulate multiple user-side energy storage inverters, the use of centralized point-to-point real-time power command transmission will bring huge data and communication pressure to the central controller. Therefore, a consistency target of the user-side energy storage output power is designed, and a leader-follower model based on the consistency algorithm is used to achieve the control rate of the output power consistency of the energy storage inverter, and power balancing is achieved by using the consistency control rate of the user-side energy storage output power.

[0052] In this embodiment, the formula for the consistency target of the user-side energy storage output power is:

[0053]

[0054] Among them, P rate,i is the rated capacity of the energy storage at the i-th user side, P o,i is the output power of the i-th user-side energy storage, and n is the total number of energy storage in the user-side energy storage cluster.

[0055] Based on the leader-follower model of the consistency algorithm, the formula for the consistency control rate of the user-side energy storage output power is:

[0056]

[0057] Among them, u i is the output of the consistency algorithm controller, z i k is the control rate function of the consensus algorithm. u is the consensus algorithm gain, b i is the indicator parameter for accepting the leader signal. If v i If it is 1, it means that the i-th energy storage accepts the leader signal, otherwise it is 0; N i is the set of user-side energy storages that maintain communication with the i-th energy storage, P ref is the output power reference of the energy storage, and is the leader power; P i set is the active power of i energy storage inverters, Q i set is the reactive power set of i energy storage inverters.

[0058] In this embodiment, the user-side energy storage distributed control logic considering SOC balance is as follows: based on the SOC transformation function, a control mode switching coefficient γ is introduced to achieve switching between power consistency and SOC consistency control, to achieve a control rate of energy storage SOC consistency, and to achieve SOC balance using the consistency control rate of the user-side energy storage SOC.

[0059] In this embodiment, the process of user-side energy storage distributed control considering SOC balance is as follows:

[0060] The SOC of the i-th user-side energy storage device at time t i The expression of (t) is:

[0061]

[0062] Among them, η i is the charge and discharge efficiency, t0 is the initial moment of SOC measurement of the energy storage device on the user side, The maximum energy storage capacity.

[0063] The formula for the consistency control rate of the user-side energy storage SOC is:

[0064]

[0065] Among them, k SOC is the SOC consistency gain; func(·) is the SOC transformation function.

[0066] In this embodiment, in SOC consistency, the SOC value of the energy storage device cannot be directly used as the consistency variable. There are two specific reasons: first, the power of the energy storage system is bidirectional, and there are two scenarios: power output and power input. When the power output is specified to be positive, as the power output increases, the energy storage SOC decrease rate will accelerate. Direct use of the SOC signal will form positive feedback and cause control failure. Second, there is an integral relationship between the SOC and the output power of the energy storage system. Direct use of the SOC signal will introduce an additional zero pole in the control system, reducing the difficulty of system control.

[0067] Therefore, the design principle of the SOC conversion function func(·) in this embodiment is:

[0068] (1) Different func(·) needs to be designed for the output and input of the energy storage system, where P o,i When it is greater than 0, func(·) is a decreasing function, P o,i When it is less than 0, func(·) is an increasing function.

[0069] (2) func(·) should be designed to have a certain degree of nonlinearity, and its growth rate in the interval [0, 1] should be lower than the growth rate of the linear function.

[0070] The SOC conversion function func(·) in this embodiment is:

[0071]

[0072] Where a and b are the parameters of the SOC transformation function.

[0073] The user-side energy storage cluster control logic of the integrated SOC balance and power balance in this embodiment is: design the switching function of the SOC balance and power balance control modes to achieve the switching between the two different control modes of output power consistency control and SOC consistency control in different scenarios. When the acquired call scenario is a normal scenario, the user-side energy storage adopts power balance consistency control; when the acquired call scenario is close to the SOC limit, the user-side energy storage adopts SOC consistency control.

[0074] The user-side energy storage cluster control process for comprehensive SOC balance and power balance in this embodiment is as follows:

[0075] The switching function between SOC balance and power balance control mode is:

[0076]

[0077] Among them, γ is the control mode switching coefficient, which realizes the switching between power consistency and SOC consistency control. When γ is 1, the controller outputs power consistency control, and when γ is 0, the controller is energy storage SOC consistency control; k pu is the power consistency gain.

[0078] This embodiment uses a multi-user side energy storage distributed control method that considers SOC balance and power balance. The user side energy storage can switch from the output power consistency control mode to the SOC consistency control mode in different scenarios to enhance the system's operational reliability. This switching mechanism ensures that when the energy storage SOC approaches the limit, the energy storage cluster can operate safely while meeting the grid regulation requirements.

In the process of selecting the control mode of user-side energy storage, the switching function of SOC balance and power balance control modes is determined based on the side energy storage cluster regulation method, and the control mode of user-side energy storage is selected according to the control mode switching coefficient in the determined switching function.
