“…In addition, peak power output of SPV is hardly available for most of the time even when Sun shines brightly. For proper utilization of the PCS capacity, combining PV and STATCOM have been suggested in numerous research papers [1,2,[11][12][13][14][3][4][5][6][7][8][9][10]. These small rating units of PV generation is near to consumers such as roof-mounted mode contribute significantly to the overall generation.…”

Solar Photo Voltaic (SPV) based distributed generation is providing a clean and green energy to meet human needs nowadays. In grid-connected mode, most of the capacity of converter circuit is under-utilized as peak power is available for a small duration in the daytime and no utilization during the night. The converter used for PV system may be modified to work as STATCOM, that is capable to convert DC to AC and can compensate reactive power simultaneously. Thus in daytime this modified PV-STATCOM system supply both active and reactive power and in the night it will supply only reactive power resulting in better utilization of Power Conditioning System (PCS). In this paper, modified PV-STATCOM is tested in the grid-connected mode through simulation in MATLAB/Simulink/SimPower under various operating conditions. The proposed system supply active and reactive power locally in the grid-connected load resulting in less burden on the grid.

Power quality is the primary issue to be taken into consideration in modern electrical systems, particularly on the distribution side, to protect sensitive loads. Long-term uses can never run out of renewable resources. Connecting STATCOM at the distribution side enhances the power factor by improving the quality of the current waveform. The reactive power range that needs adjustment by utilising PV arrays on the STATCOM's DC side. Increases due to the large rise in terms of the PV power plants' size and capacity. Cascaded H Bridge multilevel topologies can increase the flexibility and effectiveness of PV modules. The suggested approach in this paper gives outcome of reduced peak over shoot, rise time, settling time, steady state error, percentage of ripples and total harmonic distortion which improves the power quality. PV system with cascaded H bridge multilevel inverters STATCOM for harmonic suppression and to make reactive powerless. To produce modulation indices for H Bridge switching, synchronised reference frame theory is modified. H bridges' average DC voltage is managed by a PI controller, and controller gains are obtained using fuzzy, PSO, and the trial-and-error approach. To confirm the viability of the suggested approach, simulation results using MATLAB/SIMULINK are shown. The experimental setup of proposed method is carried out to validate the inverter response.

“…Similarly, in several studies, PV inverters operated as STATCOMs during daytime to provide the reactive power compensation in a distribution utility network [50,51]. However, the performance of the system depends on the rated capacity of the inverter, the constant DC-link voltage, and the maximum power point (MPP) instant time tracking in the distribution utility network [52]. In the study of [53], a PV-STATCOM was adopted with active power filtering against power quality issues in the PV system, such as transient voltages, voltage flickering, and harmonics.…”

Abstract:This study summarizes an analytical review on the comparison of three-phase static compensator (STATCOM) and active power filter (APF) inverter topologies and their control schemes using industrial standards and advanced high-power configurations. Transformerless and reduced switch count topologies are the leading technologies in power electronics that aim to reduce system cost and offer the additional benefits of small volumetric size, lightweight and compact structure, and high reliability. A detailed comparison of the topologies, control strategies and implementation structures of grid-connected high-power converters is presented. However, reducing the number of power semiconductor devices, sensors, and control circuits requires complex control strategies. This study focuses on different topological devices, namely, passive filters, shunt and hybrid filters, and STATCOMs, which are typically used for power quality improvement. Additionally, appropriate control schemes, such as sinusoidal pulse width modulation (SPWM) and space vector PWM techniques, are selected. According to recent developments in shunt APF/STATCOM inverters, simulation and experimental results prove the effectiveness of APF/STATCOM systems for harmonic mitigation based on the defined limit in IEEE-519.
