Abstract
With the current trend of deregulation, more power exchange between GENCOs
and DISCOs in different areas exists in the power system. To mitigate the
unscheduled power exchange meets the common interests of GENCOs and
DISCOs, and avoids the power over-loading on tie-lines. However, in the
current control performance standards (CPS), frequency deviations have priority
in the conventional automatic generation control (C-AGC). Thus, a storagebased tie-line control loop (STCL) on the basis of C-AGC (STCL-AGC) is
proposed in this paper, which makes a better tradeoff in the recovery of the
frequency deviations and the unscheduled power exchange. In STCL-AGC,
utility-scaled battery energy storage systems (BESS) in neighboring areas are
referred to supply and consume the same amount of power and respond to the
unscheduled power exchange. Meanwhile, as the operation of BESS is not
always positive on the recovery of frequency deviations and area control error
(ACE), CPS are involved to ensure the practical use of STCL-AGC. At last, in a
two-area interconnected power system case, promising results are shown that
the unscheduled power exchange is mitigated effectively by STCL-AGC with
small sizes of BESS.
