Distributed generation refers to small-scale electricity generation, which has gained renewed interest due to technological advancements and changing economic and regulatory environments. It is also known as embedded generation or decentralized generation. The paper discusses various technologies for small-scale generation, their benefits, and challenges. Key benefits include reduced transmission losses, improved reliability, and environmental advantages. However, challenges such as grid integration, power quality issues, and economic costs are also discussed. The paper highlights that distributed generation can contribute to energy security and reduce reliance on centralized power systems. However, it also raises concerns about potential negative impacts on grid stability and power quality. The paper concludes that while distributed generation offers many advantages, its integration into the electricity system requires careful planning and regulation. The definition of distributed generation remains a topic of debate, with various definitions based on factors such as generation capacity, location, and technology. The paper emphasizes the need for a clear and consistent definition to facilitate effective policy and planning. Overall, distributed generation is a promising but complex concept that requires further research and development to fully realize its potential.Distributed generation refers to small-scale electricity generation, which has gained renewed interest due to technological advancements and changing economic and regulatory environments.
