Solar energy and wind energy are the two most viable renewable energy resources in the world. Germany Breaks A Solar Record — Gets 85% Of Electricity From Renewable on May 8th, 2017. India and China are increasing the wind and solar capacities eight-fold to 2040. China solar–wind to attract $780 billion investment by 2030. The future will be dominated by these renewable energies than the non-renewable energies. In order to extract these energies fully, the controlling strategies play a very crucial role to control the output power. In the controlling strategies, the charge controller regulator controls the flow of electricity in the electric batteries and main grid. If the power generation sources produce more energy than the one required by the loads, the surplus energy can be used either to charge the battery or to provide a dump load. Also, in the case where the amount of energy demand is higher than the one produced, the battery will release energy to cover the load requirements until the battery is fully discharged. In this book, the developed strategy shows the control flowchart of hybrid power generation system.
