| Summary: | 碩士 === 國立中山大學 === 電機工程研究所 === 83 === This research will formulate a new algorithm for the network
senitivity calcultion. This algorithm will be incorporated in
the optimal power flow for testing. A new linear incremental
model will be formulated in the solving process and the linear
programming technique will be applied. There are already many
research works in the LP-OPF area. As a matter of fact, many
energy management systems are running the LP-OPF in real-time
with the fast decoupled DC(FD-DC) model. However, FD-DC model
needs assumptions on (1)negligible line conductances (2)small
angular differences (within a 30 degrees range) (3)constant
voltages (at their nominal values). The above assumptions are
not necessarily true, especially under severe conditions where
the system may undergo severe violations. This research will
try to develop a new model to avoid the above assumptions. The
new model will try to resolve the OPF problem with the
performance similar to the conventional fast decoupled DC
model. However, no assumptions will be needed. A decoupled
version of the new model will be also investigated. The state
variables, power-injections, and current-injections will be
analyzed to investigate the practicality of the new model. The
convergent characteristics, the robustness, storage and
performance will all be tested to see the feasibility of the
new model in handling the real-time energy management functions.
