Currently, major power systems almost invariably operate under interconnected
conditions to transfer power in a stable and reliable manner. Multi-area reliability
evaluation has thus become an invaluable tool in the planning and operation of such
systems. Multi - area reliability evaluation is typically done by considering equivalent
tie lines between different areas in an integrated power system. It gives approximate
results for the reliability indices of a power system as it models each of the areas as a
single node to which are connected the entire area generation and loads. The intratransmission
lines are only indirectly modeled during the calculation of equivalent tie
lines' capacities. This method is very widely used in the power industry, but the
influence of the various approximations and assumptions, which are incorporated in this
method, on reliability calculations has not been explored.
The objective of the research work presented in this thesis is the development of
a new method called Composite system based multi - area reliability model, which does
multi - area reliability evaluation considering the whole composite system. It models the
transmission system in detail and also takes into account the loss sharing policy within an area and no - load loss sharing policy among the areas. The proposed method is
applied to standard IEEE 24 bus Reliability Test System (RTS) and the traditional
equivalent tie-line method is applied to the multi-area configuration of the same test
system. The results obtained by both the methods are analyzed and compared. It is found
that the traditional model, although having some advantages, may not give accurate
results.
