Abstract

A microgrid is a small energy system involving local electricity generation and local distribution system containing energy storages, loads, and monitoring and protection devices. In addition to electricity, a microgrid may include thermal energy applications for heating and cooling. A microgrid can operate independent in islanded mode, it can be interconnected in the larger energy system, or it can alter between these two modes depending on the total system state.

Cellular electric energy systems are power systems composed of interconnected, supervised, and controlled cells. These cells can be thought of as microgrids interconnected to an overlaying grid. Such kinds of grid-connected microgrids are in normal operation not intended to autonomously supply an isolated area. Instead, they exchange power with the main grid and other cells and participate in the operation of the overall system by the provision of ancillary services (e.g., flexibility provision, active and reactive power control, frequency and voltage control, congestion management, restoration services, grid forming services, etc.). By the coordinated operation of the cells which compose a cellular electric energy system, an efficient, secure, and stable overall system operation can be achieved.

This Special Issue aims to explore methods, technologies, and solutions for the integration of grid-connected microgrids in the efficient, secure, and stable operation of future cellular electric energy systems.
