What is a hybrid micro-grid?

Except for the distributed generation units, a hybrid micro-grid is composed of controllable load and energy storage systems. An energy management system is important to optimize its performance.

What is the multi-energy microgrids system?

The multi-energy microgrids system (MEMGS) includes multiple microgrids and a variety of energy forms[3]. The system takes distributed power sources, energy storage devices, and loads as the main body, and aggregates small-scale distributed energy through local energy management systems and adjacent loads [4].

What is the energy management strategy for a hybrid renewable micro-grid system?

This paper introduces an energy management strategy for a hybrid renewable micro-grid system. The efficient operation of a hybrid renewable micro-grid system requires an advanced energy management strategy able to coordinate the complex interactions between different energy sources and loads.

What is hierarchical collaborative optimization for multi-energy microgrids?

We propose a hierarchical collaborative optimization configuration framework for the multi-energy microgrids system, which realizes the independent autonomy of the lower layer and the centralized coordination design of the upper layer. In microgrid, the source-load-storage interact and self-balance locally.

Can a hybrid micro-grid system control the energy flow?

The results show that the developed algorithm was able to control the energy flow between the hybrid micro-grid system and the utility grid and also to ensure a proper relation between the charging /discharging rate of the battery based on their operating conditions. In this application, the battery was charged at higher power.

How much power does a hybrid microgrid system generate?

The variable AC load for the developed hybrid microgrid system was fixed to 800 kW and the total generation power from the renewable energy sources was 1 MW.
