What are microgrids & how do they work?
1. Introduction Microgrids (MGs) are one of the main components of the future smart power grids, which are able to integrate nearby distributed energy resources (DERs) and loads at the distribution level in an efficient way. They also include several control loops and protection devices to achieve a stable and secure operation.
What is a microgrid control system?
The control system of a microgrid must continuously analyze and prioritize loads to maintain a balance between power generation and consumption. Microgrid loads are usually critical or non-critical 6. Critical loads in hospitals, nursing homes, and data centers are essential to running a facility and must never be interrupted.
What is adaptive dynamic programming in intelligent residential microgrid systems?
