Hybrid Renewable Energy System

The hybrid renewable energy system (HRES) is a combination of renewable and conventional energy sources. It can also combine two or more renewable energy sources operating in standalone mode or in network mode. In this work two models have been created in with we have proposed a model of hybrid system in which inverter is controlled by a designed internal current loop controller and wind variations are adjusted using a algorithm. It was found to be that the proposed system gives 1150 VA output which is considerably more than the 1000VA output of the system with basic voltage control. The efficiency is enhanced from 68 % to 70%.  The system cost was found to be 70483.53 units in the system having basic voltage control and with the internal current loop control, it was reduced to 66795.26 units. Thus it can be drawn from this work that while designing an inverter control strategy the proposed internal current loop control can serve the purpose with better results in terms of power, efficiency and system cost.
