[email protected] com weather condition effects is usually presented in [6] where DC-OPF procedure is used to determine minimal slice sets (MCS) up to a preset order and after that MCSM is employed to determine reliability directories. The appropriate use and presentation of the effects of concern are widely recognized as primary components in the analyses of complex systems [7]. There are two fundamentally several forms of uncertainty in electrical power system trustworthiness assessment [7, 8]. Aleatory and epistemic questions are considered in power system reliability analysis in [9] where unforeseeable uncertainty develops because the analyze system can potentially behave in several different ways. A technique for combining the failures due to ageing in power system reliability evaluation is definitely presented in [10]. It includes the introduction of a computation approach with two possible probability division models for unavailability of aging failures and setup in dependability evaluation. Negative weather just like hurricanes can easily have significant impact on electrical power system dependability [11, 12]. Among the challenges of incorporating climate effects in power program reliability evaluation is to examine how unfavorable weather impacts the reliability parameters of system components. A fuzzy inference system (FIS) built through the use of fuzzy clustering method is combined with the regional weather model to resolve the earlier problem is illustrated in [13]. A brand new computationally successful methodology for calculating the reliability indices of a volume power system using the express enumeration approach is represented in [14]. The approach utilizes topological analysis to determine the contribution of each system state to the frequency and duration directories at both the system plus the bus level. Common trigger outage is usually considered in power program reliability analysis [15]. Power system reliability analysis and quality assessment employing fuzzy common sense and hereditary algorithm happen to be depicted in [16] and [17], respectively. Cumulant method, an extremely fast computational technique is used to evaluate the dependability of BPS in this newspaper. Reliability index ‘LOLP' is definitely assessed in this intention. LOLP gives the likelihood that the obtainable generation ability will be too little to meet the daily maximum loads. The simulation effects show the LOLP of BPS is definitely 2 . 06%.

Abstract—In recent years, power devices are frequently working under very stressed and unpredictable conditions because of not only the market-oriented reform of power devices but likewise the integration of various renewable energy sources. The uncertain factors resulting from the market constraints and the inherent randomness of power set larger requirements within the reliability of electrical networks. This kind of paper presents the stability assessment of Bangladesh Electrical power System (BPS). Reliability index, loss of load probability (LOLP) of BPS is assessed using cumulant method. The rationale for using the cumulant technique is to take advantage of the computational effectiveness. BPS offers sixty one generators and a total installed capacity of 5275 MW. The maximum require of BPS is about 5000 MW. The relevant data in the generators and hourly insert profiles are collected from your National Fill Dispatch Center (NLDC) of Bangladesh and reliability index ‘LOLP' is usually assessed. The simulation effects show which the LOLP of BPS is 2 . 06%. Keywords—cumulant method, convolution, LOLP, forced outage rate, Gram-Charlier series
