“…The system produces a good quality of energy with active power only. The PI controller optimized by the genetic algorithm gives 0.89% of the total harmonic distortion (THD) less than 1.97% obtained in [22]. This value of THD satisfies the standard value given by NF C 15-100 and IEEE 519 (T HD <5%) [15], [27], [28].…”

“…Figure 12 (a) shows the deference between the proposed method and PI Classique. In Figure 12 (b), it is noted clearly that the GA-PI is better than the PI method witch parameters are determined by Ziegler method and the adaptive neural network used in [22]. proposed method gave a low total harmonic distortion (0.89%) and it is better than the conventional methods (Ziegler-Nicolson, and Naslin) used to determine the parameters of the correctors.…”

“…The results validated that the SVM allowed to obtain 1.76% of THD. Roselyn et al [22], used a fuzzy logic command which operates significantly to impove the grid current. Another voltage control method [23] showed a THD which does not exceed 3.5%.…”

This paper presents the meta-heuristic and conventional optimizations techniques for the grid connected photovoltaic solar system. The perturb and observe (P&O) and particle swarm optimization (PSO) algorithms are proposed to track the maximum power point (MPP) of the photovoltaic solar system (PVSS). The regularization of the current supplied into the grid is ensured by the proportional integral (PI) corrector whose parameters are generated by the genetic algorithm (GA). The results of these two MPPT methods are compared and showed that the PSO is more efficient than the P&O. The use of GA algorithm to determine PI parameters allowed to obtain 0.89% of total distortion harmonic (THD).

Las microrredes son fundamentales ya que permiten la integracion local de unidades de generación basadas en fuentes renovables, sistemas de almacenamiento y usuarios de energía electrica. Sin embargo, para un correcto funcionamiento, el control de la microrred es un aspecto fundamental, por lo que en este trabajo se propone, de forma didactica, una estrategia de implementación sencilla para aquellos casos en los que no se disponga de la descripcion matemática o modelo del sistema. El aporte del trabajo consiste en la propuesta de una estrategia detallada para el diseno del control jerárquico de convertidores de fuente de tensión basada en matematica difusa, que considera el funcionamiento de la microrred como aislada o conectada a la red principal. La implementacion propuesta y el análisis de los resultados obtenidos muestran que la estrategia de control jerárquico propuesta tiene un desempeno satisfactorio. Además, esta estructura de disño es escalable, robusta, aplicable en sistemas lineales o no lineales y rapidamente implementable en sistemas físicos

“…Moreover, the increasing integration of PV plants with electrical grids has motivated many researchers to analyze the stability of such systems, especially during grid faults [3][4][5][6]. For example, [3] analyzed different low voltage ride through (LVRT) control algorithms, whereas [4] applied fuzzy logic to control the active and reactive power in LVRT control systems to improve system stability. The authors in [5] introduced LVRT to a grid-connected PV system and used a battery to mitigate DC-link voltage variation.…”

This paper proposes a robust continuous nonlinear control method for grid‐tied photovoltaic (PV) inverters by combining model predictive control and integral sliding mode control (ISMC). The robustness of the proposed augmented controller is demonstrated mathematically by showing that the equivalent control signal of the ISMC system cancels disturbances to the system. Further, the proposed controller can compensate for system perturbations without knowing their characteristics, thereby simplifying controller design for the PV systems. The robustness of the proposed controller against parameter uncertainties and external disturbances was demonstrated via experimental and simulation verification.
