Multi-time scale identification for multi-energy system
Multi-energy systems have been leaping forward for its various benefits,
e.g., energy conservation and emission reduction. Coupling components are
capable of transmitting energy from one time scale system to another time scale
system, so the multi-energy system exhibits multi-time scale characteristic and
broad bandwidth, thereby causing difficulties in dynamic modeling. In this
work, two-time scale system identification is studied. A method is developed to
solve the problem, which is uses signal pre-filtering and subtraction. The high
and low frequency parts of the two-time scale system are identified separately
and then combined to form the incorporated in parallel structure. The
consistency of the method is proved and case studies are used to verify the
effectiveness of the method
