Solar Photovoltaic (PV) systems have been in use predominantly since the last decade. Inverter fed PV grid topologies are being used prominently to meet power requirements and to insert renewable forms of energy into power grids. At present, coping with growing electricity demands is a major challenge. This paper presents a detailed review of topological advancements in PV-Grid Tied Inverters along with the advantages, disadvantages and main features of each. The different types of inverters used in the literature in this context are presented. Reactive power is one of the ancillary services provided by PV. It is recommended that reactive power from the inverter to grid be injected for reactive power compensation in localized networks. For successful integration with a grid, coordination between the support devices used for reactive power compensation and their optimal reactive power capacity is important for stability in grid power.

Investigations were presented in order to eliminate the reactive power on microgrid loads fed by an off-grid and mid-power photovoltaic solar energy system (PVSES) with a static synchronous compensator (STATCOM) device. The electric network is specifically characterized by P-Q loads, ambient temperature, and widely variable solar radiation levels. Two main innovations are developed. Firstly, the STATCOM apparatus is a 5-level H-bridge inverter with capacitances as load and must totally compensates the reactive power in the network load. Secondly, this compensation is controlled by a set of fractional PI (PIλ) and model predictive control (MPC) hybrid. The efficiencies of these controllers were compared with classical PI controllers. Large simulations, without and with reactive power compensation, in steady and transient states, are carried out to underline the merits of the presented works, by performing in the MATLAB-Simulink environment.

Multilevel converters are divided into diode clamp inverters, flying capacitor inverters and cascade inverters. The main objective of this work is to design a solar energy system to move loads away from production points and study the system to improve its reliability and efficiency. And analyze the system with the inverter field-oriented feedback control under transient load conditions to analyze the efficiency of the system in driving motor loads. The simulated work in this work demonstrates the possibility of using a photovoltaic cell to power a motor via a three-phase bridge inverter. It can be concluded that this work will contribute to the analysis of solar modules for the operation of a motor using a PWM inverter. The work also aims to perform an analysis of the solar energy system that moves loads away from the point of generation. The drive commands at the load points are analyzed during the process, taking into account the transient load conditions.
