Abstract
This paper presents the problem of robust H∞ load frequency controller design and robust H¥ based approach called advanced frequency control (AFC). The
objective is to split the task of balancing frequency deviations introduced by
renewable energy source (RES) and load variations according to the capabilities
of storage and generators. The problem we address is to design an output
feedback controller such that, all admissible parameter uncertainties, the
closed-loop system satisfies not only the prespecified H∞ norm constraint on the transfer function from the disturbance input
to the system output. The conventional generators mainly balance the low-frequency
components and load variations while the energy storage devices compensate the
high- frequency components. In order to enable the controller design for
storage devices located at buses with no generators, a model for the frequency
at such a bus is developed. Then, AEC controllers are synthesized through
decentralized static output feedback to reduce the complexity. The conditions
for the existence of desired controllers are derived in terms of a linear
matrix inequality (LMI) algorithm is improved. From the simulation results, the
system responses with the proposed controller are the best transient responses.
