A multi-contingency analysis is essential to modern power systems that improve system security. It helps to identify and analyse the various possible contingencies that may arise during the operation of a power system. The anticipation of multi-contingency (N-2) cases is a very important task since most of these forced multiple outages can cause serious troubles within a short time, like severe violations of operation constraints, cascading failures, and system blackouts. Identifying these multiple outages will help with planning ahead to reduce the impact of these risks. This paper introduces an algorithm for analyzing the power system under multi-contingency analysis occurrence using the Fast Decoupled load flow method. The proposed algorithm was applied to the IEEE-30 Bus test system under different scenarios of multiple outages including the most severe case represented by the separation of bus-bars. The results show the effectiveness of the proposed algorithm regarding analysing and monitoring bus voltage, line flow, and total system losses. All programs were written in a MATLAB environment.

Analiza wieloawaryjna jest niezbędna w nowoczesnych systemach elektroenergetycznych, które poprawiają bezpieczeństwo systemu. Pomaga zidentyfikować i przeanalizować różne możliwe zdarzenia awaryjne, które mogą wystąpić podczas pracy systemu elektroenergetycznego. Przewidywanie przypadków wieloawaryjnych (N-2) jest bardzo ważnym zadaniem, ponieważ większość takich wymuszonych wielokrotnych przestojów może w krótkim czasie spowodować poważne problemy, takie jak poważne naruszenia ograniczeń operacyjnych, kaskadowe awarie i przerwy w dostawie prądu systemu. Identyfikacja tych licznych przestojów pomoże w planowaniu z wyprzedzeniem i zmniejszeniu wpływu tych zagrożeń. W artykule przedstawiono algorytm analizy systemu elektroenergetycznego przy wystąpieniu analizy wielowarstwowej z wykorzystaniem metody szybkiego oddzielonego przepływu obciążenia. Zaproponowany algorytm został zastosowany w systemie testowym magistrali IEEE-30 w różnych scenariuszach wielokrotnych awarii, w tym w najcięższym przypadku reprezentowanym przez oddzielenie szyn zbiorczych. Wyniki pokazują skuteczność zaproponowanego algorytmu w zakresie analizy i monitorowania napięcia magistrali, przepływu linii i całkowitych strat w systemie. Wszystkie programy zostały napisane w środowisku MATLAB.
