Power Enhancement by Vector Modulation Control of Inverter in Super Capacitor Integrated Hybrid System
For energy systems in remote and remote communities, an autonomous energy system based on renewable energy can be a particularly interesting and economically advantageous solution, since the expansion of the network is often impractical due to economic and technical constraints. In this research work, we designed a hybrid solar PV system with Wind energy system in as to enhance its output capacity before its integration with the grid. Also the system is integrated with a super capacitor model for handling the change in the power demand of the system. The inverter has been modeled with Vector modulation technique which has resulted in more smooth and better output result when used in combination with DC output voltage. It was concluded that magnitude of active power output is better from the system having inverter with vector modulation control as compared to the system having inverter with simple pulse modulation control. While calculating the RMS value of the active power it was found to be approximately 5000 VA and less pulsating than that of power output from the inverter having Pulse Modulation Control. Also computational methodology of the proposed modulation technique is very easy and the technique can be applied to multilevel inverter with any number of levels.
