Renewable Sources Grid Interfacing System

Fariha Khan, Hamza Talha and Haroon Rasheed::Energy demand throughout the world has been increasing rapidly. The present energy sources such as oil reserves, coal deposits, natural gas are exhaustible and getting limited in supply. Therefore, there is an urgent need to conserve available resources and utilize energy as much as possible. In this paper we propose “Renewable Sources Grid Interfacing System” for effective conservation of renewable energy resources. We exploit multiple energy sources at the same time implying load sharing principle. This investigation explores the aspects of Load Sharing phenomenon of a grid connected Hybrid Energy System (HES). In our model solar and wind energy sources have been considered. The acquired results depict that the performance can be improved by changing the phase angle and modulation index of grid inverter. Hence Renewable energy sources such as solar and wind energy can play an important role in eliminating the energy crisis in our country if utilized properly. Most of the renewable energy systems are operated in stand-alone mode, which only supply power to fixed loads. Interconnection of this system with utility is the current design trend.
