“…Based on the explanation of the previous section and phase jump compensation, in this section, in order to improve the transient performance in VSG and SG paralleled with the grid, it should be possible to make a comparison between the damping and inertia parameters. In general, the small signal base model for a VSG can be defined as (22):…”

“…where M = E v E s sinθ z /(Z v Z s Z), δ v and δ s are the power angle of VSG and SG, respectively. Assuming that Y=[ ω v , ω s ] T , N=[ δ v , δ s ] T and also by inserting the relation (30) into (22), the MG state space model can be defined as (31):…”

“…Equation (32) shows that when the moment of inertia and damping match, the power angle VSG and SG are coupled, which leads to the stability of the output frequency. Considering that the degree of instability of the system is strengthened by the inertia of the governor, by using the relation (22), which is the relationship between the output frequency and the power angle, the power angle signal can be adjusted during the transient period. Based on the fact that the capacity ratio is S v /S s = n, so from ( 25) and ( 28), it can be seen that J v /J s = K G /D pv = n, and as a result, by subtracting the active power loop in small signal models VSG and SG relative to each other, relation ( 33) is provided…”

“…In the island operation mode, the MG should adjust the voltage and frequency within the determined limits while maintaining the power balance [21]. In this regard, using a set of droop topologies without inertia reduces the reliable performance of MGs [22]. Therefore, in order to operate RES more safely, their DC/AC converter can be controlled through a VSG.…”

The main aim of this paper is to design a local controller for DC/DC converter in a battery energy storage system (BESS) and a controller based on a virtual synchronous generator (VSG) for photovoltaic (PV) converter connected to AC grid. In the DC/DC converter design, the state feedback method is used so that the voltage and current control loops are combined, leading to higher flexibility and improved damping. This flexibility, which maintains the state of charge (SOC) of BESS, is supported by the design of virtual resistance and virtual capacitor statically and dynamically. In this design method, the BESS can be independently connected to each DC bus node and detect disturbances through local measurements. In addition, the improved Pre-Parallelism (PREP) method has been used to improve the transient performance caused by the disconnection and connection of additional loads, the existence of faults, and the inherent inertia difference in parallel operation between VSG and synchronous generator (SG). In this method, the problem of phase jump caused by transient disturbances is solved by considering a cosine function in VSG design. Also, to solve the problem of inertia difference between the units, a small signal model has been presented, in which, by considering the capacity ratio of the units on the AC side, the necessary inertia for VSG can be included in the design. The proposed method is simulated by considering different scenarios in MATLAB software, so the results demonstrate the superiority of the proposed controller compared to other existing methods.

“…The authors of [11] analyzed the characteristics of wind power output and proposed an optimized VDC control strategy for energy storage participation in wind-power-containing grids, which can effectively suppress wind power fluctuations. The authors of [12], with VIC, simulated the inertial response characteristics of conventional units and energy storage because of its fast response capability to obtain a better frequency regulation effect. The authors of [13] produced a mechanism model between VIC and grid frequency for energy storage using VIC when parameter tuning and control strategy selection are used to lay a theoretical foundation.…”

For energy-storage-assisting conventional units to participate in the primary frequency regulation of a power system, firstly, based on the frequency regulation mechanism of virtual inertial control (VIC) and virtual droop control (VDC) of energy storage, we analyze the effect of the action timing of energy storage on the frequency deviation of the grid under two control methods and put forward a reasonable combination of the two control methods; on this basis, we also put forward hybrid energy storage adaptive VIC and VDC based on the demand of VIC and VDC on the power and capacity of energy storage. On this basis, based on the demand of VIC and VDC on the power and capacity of energy storage, a hybrid energy storage adaptive VIC and VDC coordinated control strategy based on supercapacitor–lithium batteries is proposed, whereby a high-power storage supercapacitor responds to inertial control signals to rapidly suppress a drop in frequency, and the high-capacity lithium battery responds to droop control signals to perform long-time droop control. The high-capacity lithium battery responds to the sagging control signal and is used to perform a long-time sagging power response; finally, in order to avoid the state of charge (SOC) of energy storage falling into a low/high working condition and losing the subsequent frequency regulation ability, an adaptive power control strategy of energy storage based on the improved logistic function is proposed. The simulation results show that under typical load disturbance, the SOC level of the proposed strategy increases by 19.17% and 30.16%, respectively, compared with that of the single-lithium strategy and no energy storage, and the SOC level of the supercapacitor and lithium battery increases by 29.4% and 2.1%, respectively, compared with that of logistic optimization.
