“…Electrical distance between buses, based on mutual admittance, is considered as a guide in partitioning a system into a SA and an EA. As contingencies do not result in considerable admittance changes in the EA, it is suggested in [15] that the statistical mean of the admittances to be used in the equivalent network.…”

“…This usually makes component outages ignored in PPF [4]. Mahraby and Allan [25] and Audomovongseree and Eua‐Apron [26] have obtained means and probability density curves of the equivalent injected powers based on the traditional Ward model and Monte Carlo simulation method. The impact of renewable energy, loads and component outages on the equivalent network are considered.…”

“…A major difficulty in adequacy evaluation of large composite generation and transmission systems is the computation time required to perform the analysis [1]. This difficulty can be alleviated using an adequacy equivalent approach which is a practical and effective way to perform detailed or repeated analysis in a selected area of interest (AI) with reduced computation time [2,3].…”

SUMMARYData requirements and large computation times are still major difficulties in bulk electric systems (BES). When small area of BES is noticed as area of interest (AI) in reliability studies, the other parts of the network can be considered as interconnected area (IA). A reduction method based on generations and loads importance of IA is presented in this paper to equivalent the IA. Generation Reliability Importance Factor (GRIF) of generation units and Load Reliability Importance Factor (LRIF) of loads with respect to power system reliability are defined for the generation and load points associated with the IA. Application of graph theory concept is used for obtaining the equivalent network. With some rules based on graph networks, an equivalent network will be obtained for this network and some nodes are remained in final network such as main nodes based on GRIF and LRIF indices. The applicability of the proposed approach is examined using the 3-area IEEE-RTS network and the results are presented and compared for various case studies.
