Energy storage system plays an important role in
operation and control of microgrid. Control strategies of
converters of superconducting magnetic energy storage
(SMES) system/battery hybrid energy storage system (HESS)
in microgrid are studied in this paper. Energy storage
converters are widely used in microgrid for achieving
bidirectional power transmission based on proportional-integral
(PI) method. However, PI controllers are not satisfactory in
robustness due to high nonlinearity and coupling
characteristics. Thus, this paper proposes an energy shaping
(ES) control based on interconnection and damping assignment
(IDA) to improve robustness of HESS converters in microgrid.
Design process includes three steps: construction of
port-controlled Hamiltonian (PCH) model, setting of desirable
equilibrium and solution of energy matching equation. (2018-10-17, PDF, 404KB, 下载38次)
