Worldwide renewable energy resources, especially solar energy, are growing dramatically in view of energy shortage and environmental concerns. The main objective of this study the design of a solar photovoltaic system in MATLAB/SIMULINK environment so as to enhance its output capacity before its integration with the grid. And to stabilize and improve the active power output from the solar system by designing an efficient controller for the inverter for DC to AC conversion based on AI optimization technique. Enhance the system reliability and efficiency by integrating it with the grid via a transformer with the desired grid voltage and frequency and studying its performance at different loads. This work provides a comprehensive design and implementation of power regulatory per phase inverter with proposed differential evolutionary pulse regulation control. Finally the work is made efficiently integrating it with the grid. The designed system is also capable of feeding reactive power to the grid when required. The computational methodology of the proposed modulation technique is very easy and the technique can be applied to the multilevel inverter with any number of levels.

Photovoltaic (PV) technology is one of the clean sustainable energy technology which sourced from the sun. However, there are many issues that can potentially degrade the system. This paper extensively discusses on the hybrid system power generation for the photovoltaic (PV) system. In addition, this paper also reviews the factor that affecting the photovoltaic system performance including the types of PV cell, the effect of ambient condition, system components, and the power quality characteristics. The performance of the monocrystalline type greater than the polycrystalline type around 5-7%. The usage of an inverter gives an impact with 8-20% of total energy losses. Finally, this paper summarises the future research work needed to overcome the drawback of the available photovoltaic systems.
