Abstract: | A method for designing feedforward and feedback controllers for
integration of stochastic sources and loads into a nonlinear networked
AC/DC microgrid system is provided. A reduced order model for general
networked AC/DC microgrid systems is suitable for HSSPFC control design.
A simple feedforward steady state solution is utilized for the
feedforward controls block. Feedback control laws are provided for the
energy storage systems. A HSSPFC controller design is implemented that
incorporates energy storage systems that provides static and dynamic
stability conditions for both the DC random stochastic input side and the
AC random stochastic load side. Transient performance was investigated
for the feedforward/feedback control case. Numerical simulations were
performed and provided power and energy storage profile requirements for
the networked AC/DC microgrid system overall performance. The HSSPFC
design can be implemented in the Matlab/Simulink environment that is
compatible with real time simulation/controllers. |
