Effects of Renewable Energy Sources

Introduction:

There has been tremendous growth in the use of renewable energy sources due to stricter regulations associated with the polluting nature of conventional sources and advances in power generation systems. This shift toward renewable energy resources explains the increase in investment in renewables worldwide.

However, the transition to a power system that relies more on renewables does not come easily. This change presents challenges, particularly in power system operation and electricity supply, as the amount of energy produced is determined by weather conditions.

This Effects of Renewable Energy Sources course focuses on the computational methods necessary for the reliability evaluation of power generation systems whose load is primarily derived from renewable energy sources.
