Abstract
To address environmental and climate issues, vigorously
developing new energy sources such as wind and solar energy
has become a common choice for countries around the world to
formulate energy policies and promote clean energy
transformation. The country has clearly proposed to
incorporate “carbon peaking” and “carbon neutrality” into
the overall layout of ecological civilization construction
and to build a new type of power system with new energy as
the main body. Under the paradigm of the new power system,
new energy is the main source of power supply, smart grid is
the hub platform, and source, grid, load, and storage
interaction and multi-energy complementarity are the
support. However, the current problem is that with the
gradual advancement of the construction of new power system,
the system voltage level continues to rise, and voltage
fluctuations become more severe. High frequency and
high-intensity voltage shocks affect the operational
reliability of key equipment; The proportion of new energy
connected to the grid has significantly increased, and more
and more new energy generation units are connected to the
grid through power electronic equipment, which exacerbates
the complexity of harmonic components in the power system,
leading to accelerated insulation aging, overheating of
critical equipment, and even shortening the lifespan of
critical equipment. Based on this background, it is urgent
to propose a new risk assessment method for new power
system, providing a quantitative decision-making basis for
system planning and operation, and ensuring the safe and
reliable operation of the system. To ensure the safe and
stable operation of the new power system, it is necessary to
conduct in-depth research on the control and operational
characteristics of the new power system and overcome
bottleneck issues such as new power system status monitoring
technology, new power system risk assessment technology, and
new power system fault diagnosis technology. This topic aims
to explore the current development status and future
development direction of key technologies that contribute to
the reliable, safe, and stable operation of new power system
from two aspects: system state assessment and fault
diagnosis.
