“…El inversor es el elemento principal de la interfaz de generación fotovoltaica (FV) y eólica con la red eléctrica convencional [1][2][3][4][5]. La función elemental del inversor es tomar la señal de 𝑐𝑑 (corriente directa) de entrada con un 𝑉𝑖 (voltaje de entrada) y convertirla a una señal de 𝑐𝑎 (corriente alterna) de salida con un 𝑉𝑜 (voltaje de salida) y 𝑓𝑜 (frecuencia de salida) [5,6].…”

“…Un inversor ideal produciría una señal senoidal pura en su salida, sin embargo, los inversores reales producen corrientes armónicas en los sistemas de potencia [3,[10][11][12][13][14][15]. Las corrientes armónicas son señales sinusoidales que a diferencia de las corrientes fundamentales (corrientes con frecuencias de 50 o 60 𝐻𝑧), tienen frecuencias que son múltiplos enteros "𝑛" de la frecuencia fundamental de trabajo del sistema y cuya amplitud va decreciendo conforme aumenta el múltiplo a razón de " 1 𝑛 ⁄ "; donde, el número "𝑛" determina el rango de la componente armónica.…”

En este trabajo de investigación se realizó un estudio del comportamiento de la distorsión armónica de corriente en un nodo de carga alimentado por la red pública de energía eléctrica y por inversores interconectados al mismo nodo. El análisis se desarrolló a través de un diseño experimental, empleando herramientas estadísticas como el análisis de la varianza y arreglos factoriales completos, aplicados a datos experimentales obtenidos mediante la configuración de un banco de pruebas con un punto de acoplamiento común con la carga, donde se integran las potencias de la red y de los sistemas renovables (fotovoltaicos), a través de inversores electrónicos. Los resultados obtenidos muestran que el impacto en la distorsión armónica de corriente en el nodo de carga depende mayormente del tipo de inversor utilizado y de la carga conectada al nodo. Además, los flujos de armónicas aparecen en mayor medida en la red del suministrador en comparación con las armónicas presentes en las cargas conectadas al nodo bajo estudio.

Introduction. The major source of energy for a long time has been fossil fuels, however this has its drawbacks because of their scarcity, exhaustibility, and impossibility of reusing them. Presently, a shunt active harmonic filter-equipped two-stage solar photovoltaic system is showing off its performance shunt active harmonic filter. The global power system has been impacted by current harmonics during the most modern industrial revolution. Novelty. The proposed work is innovative, by adopting the hysteresis modulation mode with Z-source inverter to enhance the performance of the system. Furthermore, the shunt active harmonic filter also get assists in this system for better improvement in the quality of power. Purpose. By incorporating an impedance source inverter and a photovoltaic shunt active harmonic filter methods, harmonic issues are mitigated. Methods. Load compensation is one of the services that the shunt active harmonic filter offers, in addition to harmonic compensation, power factor correction, and many other functions. The current pulse width modulation voltage source inverter method is more expensive, requires two converters owing to its two-stage conversion, has significant switching losses, and has a low rate of the reaction. The new model, in which the voltage source inverter is substituted out for a Z-source inverter converter, has been developed in order to address the problems of the existing system. Results. Rather than using a hybrid of DC-DC and DC-AC converters, the suggested system uses a shunt active harmonic filter that is powered by a photovoltaic source using a Z-source inverter. Utilizing Z-source inverter helps to address the present issues with conventional configurations. Practical value. By using software MATLAB/Simulink, this photovoltaic shunt active harmonic filter technique is analyzed. Shunt active harmonic filter, which produces compensatory current from the reference current obtained as from main supply, is powered by the photovoltaic array.

The electrical energy demand is steadily growing, and hence, the integration of photovoltaic system to the distribution networks is also dramatically increasing though it has a significant effect on the network’s power quality. The purpose of this paper is to analyze the impact of solar PV integration on the power quality of distribution networks. The study is conducted using ETAP software, taking one of the radial distribution networks available in Bahir Dar city during the peak of connected loads which has the least voltage profile. Furthermore, the optimal location of the PV in the network is done using particle swarm optimization. Accordingly, the appropriate location of the PV system is determined to be the farthest end bus (bus 34). Also, the impact in terms of voltage and current harmonic distortion on the distribution feeder network is comparatively discussed by comparing the distribution system parameters with different penetration levels of solar PV system. The simulation results obtained demonstrate that high harmonic distortion level is injected correspondingly as the penetration capacity of PV system increased which indicates that the solar PV system should be integrating only up to a maximum possible capacity the network can carry. The integration of the PV system beyond this maximum penetration level causes production of high harmonic distortion which adversely affects the system performance. At the maximum penetration level which allows the acceptable harmonic distortion limit, the total voltage harmonic distortion and current demand distortion are found to be 4.97% and 14.98%, respectively.
