“…The operating point of the SPVA is shifted to the right-hand side of the MPOP due to the higher ramp with stable operation. The SPVA voltage under the off-MPOP mode, is expressed using (12). The detailed process of the grid-interactive SECS is evinced in Fig.…”

“…The conventional control strategy [9] fails to operate at the presence of Gaussian white noise and does not support harmonics compensation capability. The aforementioned issues are mitigated using a sliding mode controller (SMC)-based multi-functional strategy, which is analysed in [12] for voltage regulation, frequency regulation of the microgrid. It yields stiff switching to the converter, which increases the power loss of the VSC.…”

“…With the increasing penetration of renewable energy resource in the power grid, the related grid codes require that the grid-connected solar PV system must have the low-voltage ride through capability so that the PV system remains connected to the grid during voltage sags for a specific period of time to provide grid support during grid faults [31,32]. The grid-connected inverter of a PV system should be able to detect the fault incident and more importantly react quickly to ensure the LVRT capability.…”

Digital-physical hybrid real-time simulation (hybrid simulation) platform integrates the advantages of both digital simulation and physical simulation by combining the physical simulation laboratory and the real-time digital simulator. Based on a 400 V/50 kVA hybrid simulation platform with 500 kVA short-circuit capacity, the hybrid simulation methodology and a Hausdorff distance based accuracy evaluation method are proposed. The case validation of power system fault recurrence is performed through this platform, and the stability and accuracy are further validated by comparing the hybrid simulation waveform and field-recorded waveform and by evaluating the accuracy with the proposed error index. Two typical application scenarios in power systems are studied subsequently. The static var generator testing shows the hybrid simulation platform can provide system-level testing conditions for power electronics equipment conveniently. The low-voltage ride through standard testing of a photovoltaic inverter indicates that the hybrid simulation platform can be also used for voltage standard testing for various power system apparatus with low cost. With this hybrid simulation platform, the power system simulation and equipment testing can be implemented with many advantages, such as short period of modelling, flexible modification of parameter and network, low cost, and low risk. Based on this powerful tool platform, there will be more application scenarios in future power systems.

“…The photovoltaic (PV) industry is continuously growing, and solar power plants are connected to the electric grid on a large scale. The prices of PV systems were continuously decreasing during the last decade [1][2][3][4][5]. The International Governmental Support in many countries, in addition to the great competition in the PV industry, yield to a further decrease in the capital expenditures of PV systems along with improvements in equipment efficiency and capacity factor.…”

Contribution of Photovoltaic (PV) systems is rapidly growing and great attention is given to the design of PV controllers to enhance both the performance of PV systems and the low voltage ride through (LVRT) capability during abnormal operational conditions. This article presents a novel application of the salp swarm algorithm (SSA) in order to optimally tune the PV controllers to enhance the LVRT of grid-connected PV systems. Enhancement of LVRT is indicated in percentage undershoots or overshoots, settling time and steady-state error of voltage response. A control strategy is applied to the DC-DC converter to obtain a maximum power point tracking operation through a proportional-integral (PI)-based open fractional voltage control. The grid side inverter controls both the point of common coupling voltage and the DC-link voltage through PI-based cascaded-voltage control. To get PI controller parameters that guarantee the optimum design of the controllers, the fitness function is optimized by using the SSA. The proposed optimal control scheme is tested under various fault scenarios and compared with other conventional optimization-based PI controllers to examine its validity under PSCAD environment. The effectiveness of the optimal control scheme is verified by comparing the simulation results with the practical results of the PV system.
