Why is reliability analysis important in microgrid development?
In the development of microgrid, its security and reliability analysis becomes an important issue in order to ensure reliable power supply. To perform reliability analysis of microgrids is still challenging in the design and evaluation process. The power output from local wind and solar energy resources is random and instable.
How reliable is a microgrid?
The reliability of microgrid includes two facts: security and adequacy. Security is related to the ability of the system to respond to the sudden disturbances arising within the system, while adequacy refers to the existence of sufficient power capacity within the system to satisfy the customer demand.
How to analyze the resilience of complex microgrid systems?
The main conclusions are as follows. Based on the analysis of the resilience of simple microgrid systems, a method for analyzing the resilience of complex microgrid systems considering parameters such as failure rate, repair rate, post-failure performance, post-repair performance, repair time, and average time between failures was proposed.
What happens if a microgrid model is not accurate?
If the modeling is not accurate, the evaluation will be inaccurate and the planning will be unreliable. In the future, the multi-state uncertainty modeling and mechanism analysis of microgrids will be focused on to provide support for reliability evaluation and system planning of microgrids.
