A Review of Renewable Energy and Power System Integration

Abstract

Wind and solar energy are two examples of the renewable energy that nations around the world are accelerating their development of in response to global climate change and energy scarcity. However, current power networks face new difficulties as a result of these energy sources' volatility and intermittency. Based on the existing literature and data, this article reviews the latest research advances in the integration of renewable energy sources (such as solar and wind) with conventional power systems. The paper discusses the main technical challenges faced in the integration process, including intermittency, stability and other issues. At the same time, this paper discusses the development of demand response, load management, machine learning, energy storage technology and smart grid technology, of which smart grid technology is the main content of this article review. The purpose of this paper is to summarize the existing smart grid technology, explain the help of smart grid for renewable energy grid connection, and provide a reference direction for future research. Finally, according to the existing policies, the paper looks forward to the future and believes that the share of renewable energy in the future grid will be increasing.
