Reactive power control in renewable rich power grids: A literature review

“…In 2014, Liu et al. [60] explored the coordinated techniques for managing the DR‐PCD and “grid‐connected inverter groups”. In 2019, Marrekchi et al.…”

“…Conventional methods OLTC transformers [51, 63, 91, 96, 97] DFIG [57, 62, 87–90, 95] SCIM [1] Capacitor banks [14, 16, 30, 32, 50, 105] Static VAR system [29, 31, 49, 60, 70, 92, 107] …”

In addition, PSCAD/EMTDC software in [32], DIgSILENT/PowerFactory in [34], dSPACE ds1104 based system in [42], DigSILENT software in [46] and OPAL‐RT's eMEGASIM and ePHASORSIM [86], PSIM software [59, 63, 64, 67, 70], MATLAB and PSIM co‐simulation platform [71], ARM CORTEX processor [75], DlgSI LENT/PowerFactory [60]: FORTRAN programming language [92], MATLAB/Simulation [1, 2, 4, 31, 39, 45, 48, 49–58, 62, 65, 66, 68, 69, 72, 73–74, 77–85, 88, 91, 93–94, 96, 97, 99, 100–103, 107, 105, 106], software PSIM [89], DIgSILENT/PowerFactory [90], ETAP simulation platforms [29], DIgSILENT/PowerFactory [34], HiL tests in the PLECS settings [104], OPAL‐RT's eMEGASIM and ePHASORSIM [86], PSCAD/EMTDC [87] have been used as implementation tools.…”

“…In [3], the secondary U‐Q control has been used. In addition, current control technique in [33], RT2FNN controller in [80], MINP model in [51], adaptive dynamic programming in [84], back stepping method in [54], emergency control strategy in [90], AVC [60], DPC‐SVM [66] have been used. Among these models, soft computing techniques like machine learning and optimization techniques have been used on large scale.…”

Research on the strategy of cooperative control between photovoltaic grid‐connected and reactive power compensation technology

“…The literature [9] proposes a control strategy of three‐phase grid inverter based on space vector modulation. A PV power station model was built with DlgSILENT/PowerFactory in [10], the coordinated methods for controlling the dynamic reactive power compensation devices and grid‐connected inverter groups have been studied, and then an optimised reactive control strategy was proposed to build the PV power station's reactive power support ability. The literature [11], a new control strategy that combines Proportion Integrity (PI) with quasi‐Proportion Resonant (PR) control under d – q rotate frame, is proposed for three‐phase grid‐connected photovoltaic inverter to achieve the zero error tracking of fundamental current as well as to suppress the selected harmonics current.…”
