6 FAQs about [Microgrid Risk Assessment]
What is a microgrid risk assessment?
Assessing risk to a microgrid essentially means finding a way to quantify the relative potential of damage that various threats in the environment can cause. Risk is a function of threats exploiting vulnerabilities to impact the operations and damage or destroy the assets.
How is risk created in a microgrid?
Risk is created when a threat can exploit an already present vulnerability in the microgrid. The magnitude of the risk is determined by the likelihood of the threat and the vulnerability, as well as the scale of damage the vulnerability could cause if exploited.
What is risk analysis for Microgrid deployment?
The process of risk analysis for Microgrid deployment involves first analyzing the business risks associated with economic operations. Next, the risks associated with the microgrid's resilience are identified and quantified.
What is the definition of microgrid resilience?
Microgrid resilience refers to building highly resilient microgrids that require a methodological assessment of potential threats and identification of vulnerabilities, and the design of mitigation strategies. This paper provides a comprehensive review of threats, vulnerabilities, and mitigation strategies and develops this definition for microgrid resilience.
Should microgrids rely on a single energy source?
For microgrids located on islands, diversification of generation resources with renewable energy can decrease the cost of operation. This is due to the high cost and risk associated with transporting generator fuel over long distances.
What physical threats do microgrids face?
Microgrids are typically vulnerable to physical threats such as natural hazards and changing climate, as well as human-induced attacks. Natural hazards and a changing climate pose physical threats to microgrids.
