“…The basic concept of the adopted droop control is shown in Fig. 6 and the typical droop characteristics [37] can be written as in (5): where, f ref is the frequency reference (1pu), dp ref is the active power reference based on power-frequency (P-f) droop controller, K bess−f is the droop parameter with the slope of 1 K bess−f . BESS droop characteristics (charging/discharging) can be demonstrated in three operating regions as shown in Fig.…”

“…Number of publications on frequency challenges related to PV penetration in power system are available. Stability studies by the authors in [3]- [5] argued that reduction in inertia increases frequency oscillations of the system. In addition, authors in [5] indicated that higher PV penetration induces dramatic frequency oscillation beyond grid operating standards that potentially threatens uninterrupted load supply.…”

In addition, authors in [5] indicated that higher PV penetration induces dramatic frequency oscillation beyond grid operating standards that potentially threatens uninterrupted load supply. Power oscillation damper [6], synchronous power controller [7], [8] and multiple-model adaptive control strategy [9] is adopted at PV terminal to damp out power system oscillations resulted from temporary power imbalances and maintain robust damping performance.…”

Increasing PV penetration significantly diminishes system inertia that affects systems' damping capability to regulate primary frequency control. Unlike wind turbine, PV energy system is incapable of providing under-frequency support because of no stored kinetic energy and could cause penalties for violating regulatory requirements. Therefore, a droop-type, lead-lag controlled Battery Energy Storage System (BESS) with a novel adaptive SOC recovery strategy is proposed in this paper to provide additional damping, enhance the inertial ability of the system with 18.18% PV penetration and which satisfy Australian National Electricity Market (NEM) regulatory requirements. The adaptive SOC recovery aims to maintain flexible battery SOC value according to load/PV generation forecast and comply with future events such as peak PV generation or lower PV output during the passing cloud periods. The proposed adaptive SOC strategy regulates SOC based on the value of charging current and moreover, adaptive SOC recovery does not affect the maximum SOC limit for the regular network event. Simulation results demonstrate BESS efficacy in mitigating the adverse inertial impact of PV and accomplishing mandatory grid requirements. Moreover, the proposed adaptive SOC recovery shows the flexibility of BESS for SOC management planning in accordance with future events forecast.

“…As reported in in [82], the POD at PV is designed by using wide-area signal. The damping ratios of the local modes are slightly increased by the integration of POD at PV, while on [83,84] the global modes are improved for systems with high penetration of PV power plants.…”

“…The influence of the PV-based penetration on the grid oscillations and its dynamic stability will vary according to the changes in the system operating's condition, which is due to the effects of damping torque impact from the PV system which can be positive or negative. The most serious operating condition for the PV-based power generation unit will arise when the sign of the damping torque's contribution of the PV system is changing [83][84][85].…”

This paper presents an overview of the impact of high penetration of photovoltaic (PV) systems in low-voltage distribution networks (LVDNs). High integration of solar PVs in the LVDNs has severe implications on the system parameters, efficiency, and stability. This paper also introduces the methods that have been driven to overcome these effects to preserve the steady-state conditions in the system during excessive penetration of PV generation units. A comparison between the contributions and shortcomings of the most recent researches for overvoltage mitigation strategies has been driven. Also, it includes comparing different overvoltage mitigation methods to handle the impact of the overvoltage under high penetration of PV units in the LVDNs. Besides, it presents a comparison between overvoltage mitigation methods based on their pros and cons.
