  Research in monitoring and control of microgrids has been ongoing for the
last two decades to protect and enhance communities' socio-economic
performance. However, of increasing concern are the possible cyber-physical
threats that could disrupt the provision of macrogrids' energy services to
critical infrastructure and consequently impact the resilience and
sustainability of communities. As cyber-physical systems, microgrids are not
immune to these threats. Advanced monitoring and control are critical for
real-time operations of microgrids and, therefore, directly influence
communities' resilience. Research trends in monitoring have recently shifted
from normal situational awareness in forecasting, state estimation, and
prediction to anomalies' analysis and cyber-physical attacks' detection to
support resilient control systems. In addition, confounding the interpretation
of research findings is the lack of a widely accepted definition, analytical
methods, and metrics to consistently describe the resilience of power grids,
especially for microgrids. This paper provides an overview of current research
in microgrid resilience and presents an outlook for future trends.
