Decentralized Control Architecture for Microgrids

Shailendra Kumar Ray , Krishna Tomar

Since its establishment in the late 1800s, the electrical infrastructure has continued to grow at a steady rate for the past 100 years. Due to the increasing dependence on electrical energy, this infrastructure will be in greater demand. Infrastructures are at their limit, and equipment must be upgraded on a regular basis. As an example, if the power lines were adequate for domestic and commercial loads, but the adoption of electric vehicles continues to grow, an upgrade might not be feasible. A better alternative is the micro grid concept, or localized generation and consumption. However, because the generation sources are dispersed, controlling them and coordinating them becomes extremely difficult. Micro grid architectures with localized control are proposed as a solution to this problem. Here's a micro grid setup with separate sources integrated on a common DC bus, as well as battery storage and power monitoring and protection systems in-built.
