dc.description.abstract | This paper proposes a 2-sliding mode observer to detect and reconstruct a certain class of load altering
faults in a power network. The observer design is based on the recently proposed multivariable super-twisting
structure. The IEEE benchmark power networks used to test the scheme are modelled as a semi-explicit
class of differential algebraic equations (DAEs). For the purpose of developing the detection scheme, only the
phase angles of the generators are measured, which represent a subset of the differential states of the DAEs.
The objective is to estimate the differential states (the phase angles and frequencies of the generators), the
algebraic states (the phase angles of the load bus tensions) and to reconstruct a class of load altering faults
affecting the network. The proposed observer is assessed in simulation on two IEEE benchmarks: the 9-bus
and 14-bus networks, so as to verify its capability to correctly estimate the differential and algebraic states
of the network in spite of its complexity and uncertainty. Moreover, the capability of the proposed scheme
to detect the presence of a load altering fault, to exactly identify its position in the network, and to precisely
reconstruct the shape of the fault itself is shown and discussed. | en_GB |
