El presente trabajo investigativo presenta el diseño y la implementación de un filtro activo de potencia (APF) híbrido, que tiene como objetivo lograr la corrección de los niveles de voltaje cuando estos son afectados por la integración de generación fotovoltaica dentro de la red de distribución eléctrica. Para alcanzar el objetivo propuesto, se hace uso de la técnica de control de modulación por vector espacial resultando en la reducción de armónicos de corriente y voltaje. El diseño propuesto se lo prueba en el sistema de prueba de la IEEE de 13 barras, en Simulink- MATLAB. El APF con la estrategia propuesta tiene excelentes resultados, y permite la inserción de sistemas energéticos fotovoltaicos en la etapa de distribución. Dependiendo la selección del APF de alto potencial se podrá determinar cuan significativa es la corrección sobre el perfil de voltaje, también se reflejará una reducción en las perturbaciones de carga y la compensación de los armónicos se verá mejorada.

“…On-grid inverter control can be done so that the current injected by the grid has minimum harmonics [4]. Several control methods for reducing harmonics in PCC have been discussed using: Synchronous Reference Frame theory [5], fuzzy [6], [7], adaptive noise cancellation [8], sliding mode control [9], Lyapunov approach [10], direct power control with space vector modulation strategy (DPC-SVM) [11], hybrid automaton control [12], and virtual impedance [13], [14].…”

Currently, most photovoltaic (PV) sources are connected to the grid. This research discusses single-phase on-grid PV inverters. A two-stage inverter which consisted of a boost-type DC-DC converter and a single-phase inverter, was used. In addition, the inverter improved the power quality to deliver PV maximum power. The entire power generated by PV was to be delivered to PCC, and power quality in PCC was also improved. In this system, the grid only drew or supplied active power. The P&O algorithm, as a simple algorithm, was used to control the boost converter to obtain the maximum PV power. In a single-phase inverter, the DC link voltage regulation was carried out using the PI control (outer loop), while the hysteresis control was used to control the output current (inner loop). The voltage control regulated the power delivered from the PV to the PCC by maintaining a constant DC bus voltage at the specified value. With the current control, a single-phase inverter provided two compensations: reactive power and harmonics. In this research, a simulation to control a two-stage inverter was created by using PSIM. Irradiation for PV was varied between 0-1000 W/m 2 for 5 seconds. The simulation results showed that the controls performed could work well, as shown by the maximum power injection from the PV to the PCC in which the grid current was sinusoidal (harmonic mitigation) and reactive power compensation was performed.

“…8,9,[12][13][14] In a three-phase system, the SAPF can be inserted at each phase of the nonlinear load and this way proves to be much suitable than implementing a higher power three-phase SAPF. [15][16][17] The half-bridge SAPF topology offers interesting practical benefits compared to the conventional full-bridge converter. For instance, it allows the reduction of the switching losses of the given power semiconductors, thus increasing the reliability of the system.…”

This paper addresses the nonlinear controller design and the stability analysis of a shunt active power filter (SAPF) interfacing a solar photovoltaic (PV) system that consists of a couple of PV panels, a single-phase two-stage IGBT half-bridge SAPF and two identical DC link capacitors. We seek for the considered system the fulfillment of three control objectives: (a) extracting the maximum PV power using an appropriate maximum power point tracking (MPPT) algorithm; (b) regulation of the DC link capacitor voltages to the reference provided by the MPPT controller hence ensuring the exchange of power between the PV source and the AC power grid; (c) compensation for reactive power and undesired harmonics caused by the nonlinearity of electronic power loads, that is, performing power factor correction (PFC). The control objectives are achieved using a new two-loop cascaded controller. The Backstepping approach is applied in the inner loop to perform PFC. A filtered proportional-integral (PI) controller is applied in the outer loop to ensure tight regulation of the PV voltage. The MPPT control is implemented using a perturb-and-observe (PO) algorithm. The performance of the closed-loop system under the two-loop control strategy is formally analyzed through the Lyapunov approach applied to the averaged model. Numerical simulations are performed in MATLAB/SimPowerSystems environment to validate the design methodology and to confirm the theoretically predicted performances of the system under the proposed nonlinear controller.average analysis, Lyapunov stability analysis, nonlinear control, power factor correction, shunt active power filter, solar photovoltaic system List of Symbols and Abbreviations: L g , grid inductor; r g , grid resistor; R, load resistor; L, load inductor; C pv , filter capacitor; r f , filter resistor; L f , filter inductor; N s ,N p , number of connected modules in series and in parallel respectively; G, irradiance; T, temperature; μ, binary switching signal; i g , grid current; v go , grid voltage; i f , filtering current; i L , load current; i pv1 , i pv2 , PV output currents; v pv1 , v pv2 , PV output voltages; u, continuous control input; β, external control signal; P pv , PV panels power; v f , inverter output voltage; v g , voltage at point of common coupling; I f , peak value of output filter current; V f , peak value of inverter output voltage; θ 1 , phase of the voltage at point of common coupling; θ 2 , phase of the output filter current; χ, square of the PV voltage; u Ã , Steady state value of u; V , Lyapunov function candidate; f PWM , switching frequency; Q g , reactive power; T g , grid period; P g , active power; c 1 ,c 2 , c 3 , c 4 , controller parameters; ω g , angular frequency; IC, incremental conductance; IGBT, insulated-gate bipolar transistor; MPP, maximum power point; MPPT, maximum power point tracking; PCC, point of common coupling; PFC, power factor correction; PI, proportional-integral; PO, perturb and observe; PV, photovoltaic; PWM, pulse width modulation principle; SAP...
