The Impact

In this paper, a new multi-port DC-DC power converter used to deal with the intermittent nature and slow response in renewable energy applications is proposed. The proposed converter integrates a DC-DC converter and a DC-AC inverter, and the proposed circuit integrates various renewable energy sources in addition to the energy storage unit. By combining renewable energy sources with a statistical trend to offset each other, the impact of the intermittency can be considerably minimized. This combination increases the overall system reliability and usability. Moreover, integrating such systems with energy storage systems can overcome the slow response issue of renewable sources. It can provide the additional energy required by the load or absorb the extra energy provided by the power sources, which greatly improves the dynamics of the overall system. The proposed converter can reduce the system cost and size and improve the efficiency and reliability. The operation principle is studied in detail, and the design considerations are provided. The proposed architecture and its control strategy were analyzed and studied using the Simulink/MATLAB environment. Finally, the feasibility of the proper operation of the studied converter was experimentally verified based on the results of experimental studies conducted on a 300 W prototype implemented in a laboratory.

Overall Performance

Multilevel inverters (MLIs) have been extensively used and gained interest over last few decades in industrial and grid connected renewable energy applications because of its numerous merits. Besides various advantages like obtaining reduced harmonic distortion and lesser dv/dt stress across switches it has the capability of generating any number of levels. The theory of multilevel concept was initiated for high power and high/medium voltage applications as they are helpful in interfacing with renewable energy sources. By proper combination of the switches it generates a stair case output with reduced harmonic distortion because of this MLI is widely used and it became one of the advanced power converter topology. The rise of new topologies has attained importance over conventional multilevel inverter topologies, which generates more number of levels with reduced switch components. This paper presents various conventional MLI topologies and hybrid MLI topologies for renewable energy applications. Also, this review paper includes different modulation strategies which plays an important role to improve the overall performance of MLI.

Hybrid Renewable Energy

Renewable energy provisions must be extracted in a more resourceful way, with a power converter added to the mix. If the supply-demand curve rises with the seasons, it becomes clear that renewable energy sources are used to provide clean energy. This clean energy cannot be used on load directly due to fluctuating conditions, to solve this problem a modified DC to DC converter with a ripple-free output is introduced. The Vertical Axis Wind Turbine (VAWT) and Solar PV were combined to achieve a constant DC output in a hybrid renewable energy conversion system. For renewable energy applications, a redesigned converter with ripple-free output is used. The simulation is made under MATLAB/SIMULINK and experimental parameters were measured using a nominal prototype.
